Experts say there are three major problems in the study of lithium batteries in China

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. Compared with the developed countries such as Japan and the United States, which are at the forefront of the development of lithium batteries, China has a certain gap in the manufacturing accuracy, equipment and standards of lithium batteries. "

Experts told reporters that there are currently three major problems in the domestic lithium battery research. The first is the issue of consistency in manufacturing. Due to the gap in the manufacturing process and equipment of lithium batteries, the production process of lithium batteries in China is uneven, and the manufacturing standards are not yet consistent. Lithium batteries used in electric vehicles are all in series or in parallel. If the consistency problem is not solved, the lithium batteries produced can not be applied to electric vehicles on a large scale.

The second issue is intellectual property rights. At present, China has made breakthroughs in the research of lithium iron phosphate batteries. However, because the United States has patents in this area, although we can independently develop some links, we still do not know how to deal with the issue of intellectual property rights.

The third is the screening of raw materials. It is not possible to import all the raw materials used for lithium battery production. It is mainly taken from China. However, domestic raw materials must pass international certification and the lithium batteries produced can be internationally recognized. Therefore, there are still some problems in the raw material certification process.
