Literacy: principle of lithium battery and classification

Source: 2020 - 04 - 06 hits: when time popularize knowledge of lithium battery: the concept and classification of industry and information technology, has launched the lithium ion battery industry standard conditions, explicitly points out that the lithium battery and lithium battery products access principle. We also know that cell phone use in our daily life are lithium batteries, lithium batteries is what? What are the characteristics of lithium battery? What is the classification of the lithium battery? With these questions, the reporter recently interviewed China battery industry association of relevant experts, their concepts, characteristics and classification of lithium batteries for the popularization of the system. First of all, what is a lithium battery: the lithium battery is due to the great inventor Thomas Edison, the application principle of lithium is common chemical oxidation reduction reactions of discharge principle: li + summary = LiMnO2 just because lithium is very active chemical properties, therefore, the processing, storage, use lithium need very stringent environmental requirements, therefore, has long been no lithium battery is applied to the actual production and life. But the development of modern science and technology is very good solve these problems, the lithium battery has become the mainstream of battery products. From what has been discussed above, we can know that the lithium battery is made of lithium metal or lithium alloy anode materials, using nonaqueous electrolyte solution. Again, the main features of lithium-ion batteries: can than is the largest lithium battery characteristics, than can refers to the energy per unit volume or unit weight; Second, the lithium battery products small size, light weight, intelligent portable; In addition, the lithium battery has a stable discharge voltage, low self-discharge rate, wide working temperature range, long service life, pollution-free, no memory effect, etc. At present, new energy vehicles and lithium battery industry is in a critical period of development, is facing unprecedented opportunities, also faces enormous risks and challenges. Since this year, ATL and LG, Japan and South Korea, such as lithium battery industry giant industry in our country, the scale of the expansion, but the lithium battery industry in China in a small scale, scattered distribution and stage of development, low levels of repetitive construction and ATL and LG, Japanese, Korean, lithium battery industry the huge gap is widening, the lithium battery industry giant with tesla has formally signed. However, long-term since, the bottleneck of China's new energy vehicle development is restricted by the development of lithium battery, therefore, increasing the government's attention and attention. Finally, the classification of lithium battery: generally speaking, the lithium battery can be divided into two categories: rechargeable batteries and rechargeable batteries. Rechargeable class is also called secondary battery, i. e. , commonly known as the battery. Do not charge type is known as the disposable batteries.
