Lithium batteries mainly refers to the use of lithium in the electrode material as the main active substance of a class of batteries. In this definition, lithium batteries refer to a class of batteries, including lithium primary batteries and lithium secondary batteries. A battery can not be recharged again, the secondary battery can be used repeatedly charge and discharge. Lithium batteries mainly lithium manganese batteries, lithium-sulfur batteries (of course, there are secondary lithium-sulfur batteries), lithium thionyl chloride batteries, lithium sulfuryl chloride batteries. Watches, calculators, computer motherboard CMOS used in the three lithium batteries, mainly lithium manganese batteries. Other lithium battery in the civilian as if rare. We usually say lithium batteries, such as mobile phone lithium battery, laptop lithium battery, are lithium secondary battery. Lithium secondary batteries also have a variety of, but the most common lithium-ion secondary battery, referred to as lithium-ion battery.
Currently on the market using secondary batteries are mainly nickel-metal hydride (Ni-MH) and lithium ion (Li-ion) two types. Lithium-ion batteries have been mass production of liquid lithium-ion battery (LiB) and polymer lithium-ion battery (LiP) two. So in many cases, the battery marked Li-ion, must be lithium-ion battery. But not necessarily a liquid lithium-ion battery, there may be a polymer lithium-ion battery. Lithium-ion batteries are improved products for lithium batteries. Lithium batteries have long ago, but lithium is a highly active (remember its position in the periodic table of the elements?) Metal, it is not safe to use, often in the charge when the combustion, burst (Such as cobalt, manganese, etc.) so that lithium really achieved a safe, efficient and convenient, and the old lithium battery also will be the same as the lithium-ion battery, Basically eliminated. As for how to distinguish them from the battery logo can be identified on the lithium battery Li, lithium-ion battery for Li-ion. Now, the use of laptop and mobile phone so-called "lithium battery", in fact, are lithium-ion battery. The basic structure of modern batteries, including positive, negative and electrolyte three elements. As a kind of battery, lithium-ion battery also has these three elements. General lithium-ion technology uses liquid or inorganic colloidal electrolytes, and therefore requires a strong shell to contain combustible active ingredients, which increases the weight and cost of the battery, but also limits the size and shape flexibility. In general, the minimum thickness of a liquid lithium ion secondary battery is 6 mm, and it is more difficult to reduce it And the so-called polymer lithium-ion battery is in the three main structures at least one or more than the use of polymer materials as its main battery system. A new generation of polymer lithium-ion battery in the degree of polymerization has been very high, so the shape can be thin (thinnest 0.5 mm), any area and any shape, greatly improving the flexibility of the battery design Sex, which can meet the needs of the product, made of any shape and capacity of the battery. At the same time, the polymer lithium-ion battery unit energy than the current general lithium-ion battery increased by 50%, its capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance and other aspects of lithium-ion batteries are larger Increase the range. Lithium ion (LiB) batteries currently sold on the market are likely to cause the safety valve to rupture in the event of overcharging, which is very dangerous, so it is necessary to install a protective IC line to ensure that the battery will not be over Charge the situation. The polymer polymer lithium-ion battery, this type of battery relative to the liquid lithium-ion battery has a good charge-discharge characteristics, so the protection of IC lines on the requirements can be appropriately relaxed. In addition, the polymer lithium-ion battery can use the IC constant current charging, and lithium-ion secondary battery used by the CCCV (Constant Currert-Constant Voltage) charging method compared to the time required to shorten the number of waiting time.
Graphite export no added value, corporate R & D investment microblogging Graphite is a strategic non-metallic mineral resources, can be widely used in new materials, machinery, energy and other fields, is also following the rare earth, China has another advantage of mineral resources. "Similar to the rare earth industry, graphite is China's traditional export commodities, China has about nearly a thousand graphite enterprises, the main production of low-grade high-carbon graphite, high purity graphite, differential graphite and expandable graphite and other products, these graphite products are mainly exported The United States, Japan, the European Union and other countries, but the export price is very low, about 2,000 yuan / ton -4000 yuan / ton.After foreign purification processing can be sold to 100,000 yuan / ton -20 million / ton, the price The gap is huge. "Yesterday, a brokerage analyst said. Rare earth industry is also the case, China's exports of rare earth products are mostly raw materials, and there is no number of value-added products in recent years by the policy and the protection of rare earth resources, China's rare earth exports are decreasing year by year, But still based on raw materials. According to customs statistics show that the current export of natural graphite products are mainly graphite powder, the same is the raw materials, the number of exports in 2013 and 2013 were 440,000 tons, 250,000 tons and 250,000 tons. "The reason why the export products to produce the main raw materials such as the situation, mainly due to China's enterprises by the financial constraints, shortage of talent and foreign technology monopoly, making China's lack of innovation in the graphite industry, high-tech application product development is slow, Science and technology content is not high, industrial advantages are not strong.As the main product research and development of graphite enterprises, the lack of technological research and development awareness of innovation, scientific research funds into a serious shortage. "Industry experts said. According to public information, according to China's graphite capital Jixi, for example, in the survey of 37 graphite enterprises, there are only four R & D costs, R & D costs only 3.8% of all the main business income. "China's graphite industry as a whole the rapid development of the market, but more low-end products, and the existence of the expense of the environment at the expense of the use of cheap labor to produce low-quality products to profiteering the phenomenon of low-end market chaos." Some analysts pointed out.
The new wireless charging station developed by the European Union can exchange charging data with the car, including user code, supplier code, charging duration and power meter. This information exchange process is controlled by a tablet computer placed in the car, thus simplifying direct communication between the driver and the charging station. Researchers at the project said they were also developing a new application that could alert the driver about the location of the charging station and ensure that the charging station and the vehicle were able to communicate. In fact, the major manufacturers have launched a support for wireless charging electric vehicles. As early as 2013, Nissan will choose the world's best-selling pure electric car hear the wind as a promotion of wireless charging technology models. July 2014, Mercedes-Benz and BMW jointly announced to cooperate in the development of electric vehicle wireless charging technology. Mercedes-Benz will be based on the new S-level test, and BMW plans to take the lead in the application of i8 body. Audi at the 2015CES show, showing the latest Audi wireless charging equipment, this can automatically lift the power supply coil wireless charging technology, enough to deal with the chassis of the higher SUV. Under the road buried in the grid, to achieve side of the side of the charge Of course, for the electric car wireless charging technology is not without any drawbacks, such as the case of wireless charging is usually slower than the cable charging half of the beat, electric car mileage is inherently limited, if the charging speed and then slow down, no doubt affect its use The In order to solve this problem, EU researchers are also developing wireless charging technology in the state of car driving, hoping to help significantly increase the mileage of electric vehicles and reduce the size of the vehicle energy storage system. Researchers believe that if you can plan along the road with a sensor panel, for the travel of electric vehicles in charge, it is expected to extend the mileage of electric vehicles. This way of using the road surface for electric vehicle wireless charging is likely to be the future direction of development, compared to the charging station and other facilities on the ground, it does not need to take up the ground space, and electric cars do not need to stop to charge, you can save time. In the driving process, the electric car power diminished, this is really a cool thing. In fact, the "charging for electric vehicles in the car," the concept of wireless charging, before the EU has been put forward and tested. In fact, Volvo started a project called "Grid Road System" as early as 2012 and built a test road about 400 meters at the H-llered test center in Sweden. The road is covered with a cable, when the test truck through this road, the vehicle will automatically start with the cable connection, 750V DC will charge the vehicle. While the electric car wireless charging has entered the Korean people's daily life. 2013, South Korea Gumi City, laying a 12 km long radio charging section, pure electric bus driving on the road while driving side of the charge. In August of this year, England Highway and British Transport Minister Andrew Jones also announced that the "dynamic wireless power transmission" technology test is expected to start later this year, the test period of 18 months. The system connects the transmission line to the coil under the road surface and transmits the power to the receiving coil inside the vehicle. The electric car or hybrid vehicle with the appropriate equipment installed can charge the battery only by traveling on this road surface. The EU said that from October 2014 to October 2015, the research team in the northern French city of Duai on the new charging station to test, and after the end of the test to assess the efficiency and feasibility of wireless charging, and its to the electric car The benefits of the user and the impact on the grid. Wireless charging technology has been used in many areas, such as electric toothbrushes, remote control, and mobile phone wireless charging. At present, electric vehicles must first check the charging pile, and then connected to the cable charging, and wireless charging will be more convenient. Image to say that the charging pile and other cable charging method as a cable router, a network cable can only guarantee a computer network, and wireless charging can be used as multiple terminals at the same time to provide network traffic WiFi. The use of wireless charging method, a parking lot of a charging base station, you can charge a number of electric vehicles within a certain range.
Industry Overview Because of its special structure, graphite has many characteristics such as high temperature resistance, thermal shock resistance, electrical conductivity, lubricity, chemical stability and plasticity. It has been indispensable for military industry and modern industry and high, new and sharp technology development. The important strategic resources, industry, the Government of graphite strategic resources are increasingly valued, so that the rapid rise in the price of graphite products. At present, due to the rapid development of China's world lithium-ion battery, pulling the demand for graphite materials, not only a substantial increase in the benefits of the graphite industry, but also makes a large number of social funds continue to pour into the graphite and its derivatives industry. The main reason is that the graphite can be surface modification and structural adjustment of the original material, so that part of the disorder or in the formation of various types of materials in the nano-hole, hole and channel structure, increase the lithium ion embedded and de-embedded Reaction, as its anode material, so that lithium-ion battery with high pressure, high capacity, long life and other characteristics. Lithium batteries mainly by the cathode material, anode materials, diaphragms and electrolytes, etc., its performance depends largely on the anode material, the material in the lithium-ion battery cost ratio of 5% -15%. Industry market size Lithium ion battery industry prospects and lithium battery development status of solidarity, according to China Electronic Information Industry Development Institute CCID Zhi library recently released "lithium-ion battery industry development white paper (2015 Edition)" data show that: 2014, the global electric car, Electric bicycles, energy storage and other markets for rapid development, led the global lithium-ion battery industry scale steadily expanded to 24.9 billion US dollars, an increase of 12%, an increase of more than 9 percentage points decline in 2013. By capacity, the global lithium-ion battery market size reached 53.6GWh, an increase of 21%. The development of the global lithium-ion battery industry presents four characteristics: First, the driving effect of power battery appears; Second, the focus of industrial development to further transfer to China; Third, the pace of technological innovation gradually accelerated; Fourth, industry consolidation efforts continue to strengthen. The global lithium-ion battery industry is currently concentrated in China, Japan and South Korea, the three occupy about 95% of the global market share. In 2014, the global lithium-ion battery industry pattern has not changed. Japan's growth rate began to pick up, South Korea's growth rate fell significantly, China's steady growth momentum, and China's negative material industry continues to benefit from the downstream demand for lithium battery growth, while its own situation of the situation rose prices. According to media research shows that in 2014 China's lithium battery anode material production of about 51,600 tons, up 35,000 tons in 2013 increased by 47.33% in 2015 China's negative material production 72,800 tons, an increase of 42.7%, while its output value of 3.88 billion Yuan, up 35.2% year on year in 2014. But with the gradual popularization of new energy vehicles, the future market demand for negative materials will still be a huge gap, its structure is also constantly optimized. One of the fastest growing demand for negative materials will be artificial graphite, the current average price of artificial graphite anode material has been higher than the natural graphite.
