Experts told reporters that there are currently three major problems in domestic lithium battery research.

　　Experts said: "The state attaches great importance to the research of lithium batteries. In the '863' project, the state has invested a total of 66 million yuan, all of which will be used for the research and development of lithium batteries. We are at the forefront of lithium battery research and development with Japan and the United States. Compared with other developed countries, China has a certain gap in the manufacturing precision, equipment, standards and other research and development details of lithium batteries."

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

　　Next is the issue of intellectual property rights. At present, breakthroughs have been made in the research of lithium iron phosphate batteries in China, but because the United States has patents in this area, although we can develop independently in some aspects, we still don’t know how to deal with the issue of intellectual property rights.

　　The third issue is the selection of raw materials. It is impossible to import all the raw materials used for the production of lithium batteries, mainly from domestic sources. However, domestic raw materials must pass international certification before the lithium batteries produced can be internationally recognized. Therefore, there are still some problems in the raw material certification process.
