New energy vehicles have eliminated the pollution of the atmosphere brought by the exhaust emissions of traditional fuel trucks, but the pollution of the environment caused by batteries after waste has brought new problems to the society The policy has spared no effort to provide various subsidy programs and guidance, but there is still a long way to go.

12 Lithium-ion batteries(also known as rocking chair batteries) refer to two different secondary battery systems that can reversibly insert and remove lithium ions from the lithium ion embedded lithium compounds as positive and negative batteries So what is the principle of lithium-ion batteries? The following small editor to introduce the principle of lithium-ion batteries.

The prologue of the new energy passenger car industry may be openedRecently, Hebei Yinlong, located in the Wu'an New Energy Industrial Park in Hebei Province, is experiencing a decline in orders and production stoppages.

The reporter learned from the new energy and materials chemistry Research Office of Tsinghua University's Institute ofspecial and new energy technology that the industrialization of catalyst production of key fuel cell materials has been overcome by the joint research and development team of the hydrogen fuel cell laboratory of Tsinghua University and a technology company in Wuhan At present, the catalyst has 17 patents, with a capacity of 1200 grams per day, and the price is only half that of imported products.

The electrolyte is an Ionic conductor that acts as a conduction between the positive and negative poles of the battery It is composed of lithium electrolyte salts, high-purity organic solvents, and necessary additives and other raw materials in a certain proportion.

According to a report released by the Australian Mining and Exploration Association, the proportion of countries in different sectors of the global lithium industry value chain in 2017 is as follows:Mining: Australia 51 %, Chile 29 %, Argentina 14 %, China 5 %, United States 1 %Refining processing: 89 % in China and 11 % in ChileElectrochemistry: 75 % in China, 10 % in South Korea, 10 % in Japan, and 5 % in other countriesLithium batteries: 50 % in China, 20 % in South Korea, 20 % in Japan, 8 % in the United States, and 2 % in the restBattery assembly: 53 % in Japan, 20 % in China, 14 % in South Korea, 9 % in the United States, and 4 % in the restThe page contains the contents of the machine translation.

Overcapacity of power cells is likely to worsenOn November 16, 2017, Liuyanlong, Secretary-General of the China Chemical and Physical Power Industry Association, put forward the above views at the second International Summit on Power Battery Applications.

Recently, the state's policy of encouraging individuals to purchase new energy vehicles is about to emerge, which has caused the already hot new energy car related industries to heat up again In this regard, experts said that even with car purchase subsidies, the market acceptance of new energy vehicles, especially hybrid and pure electric vehicles, also requires a certain amount of time to "pre-heat", but, the new energy vehicle supporting industry, In particular, power lithium-ion batteries(hereinafter referred to as lithium-ion batteries) have shown a trend of overcapacity worldwide.

How long do different types of rechargeable batteries need to be recharged? If the charging time is not long enough, will it affect the battery's service time? If the charging time is too long, will it cause a fire?How long the battery will be filled depends on the nominal capacity of your battery The larger the capacity, the longer the charging time required.

Experts said: "The state attaches great importance to the research work on lithium batteries In the '863' project, the state has invested a total of 66 million yuan, all of which are used for the research and development of lithium batteries.
