Vacuum pumps for lithium batteries

Development of Lithium Batteries

China is currently the second largest CO2 emitter in the world, and shows an upward trend. It is predicted that China will become the world’s largest CO2 emitter in many years. Therefore, China is facing increasing pressure to reduce carbon emissions. According to the statistics of OICA, automobile exhaust has accounted for 16% of the total CO2 emission. Therefore, it is imperative to promote the use of clean energy vehicles.

Batteries are the biggest bottleneck in the technology and cost of new energy automobiles. They are also the most profitable link in the new energy automobile industry chain, and the profitable profits will be maintained for a long time. The power battery industry is growing from scratch, and its market capacity is about 32.5 billion from the current billion to 2018. It will grow rapidly in the next few years. The huge growth space will benefit the whole industry chain.

There is a complete domestic lithium battery industry chain. BYD, Bike and other companies are in the forefront of the global lithium battery industry, and they are not lagging behind foreign manufacturers in the key battery composition areas of power batteries (BYD is the first commercial plug-in hybrid vehicle F3DM in the world, Tianjin Lishen will cooperate with Meyer to produce power batteries). The overall scale and technical competitiveness of the industry is not high. Obviously lagging behind foreign countries.
