The Ministry of Industry and Information Technology of the People's Republic of China has revised the Regulatory Conditions for the Lithium Ion Battery Industry and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry, forming the Regulatory Conditions for the Lithium Ion Battery Industry (2018 version) and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry (2018 version), which will be formally implemented from February 15, 2019. This method greatly strengthens the management of the lithium-ion battery industry, guides the transformation and upgrading of the industry, vigorously cultivates strategic emerging industries, and promotes the healthy development of the lithium-ion battery industry. There is no doubt that the new national standard for electric vehicles has had a significant impact on lead-acid batteries

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

The lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the negative electrode material and carbon as the negative electrode material. During the charging process, part of the lithium ions of the lithium iron phosphate will escape, pass through the electrolyte to the cathode, and intercalate the cathode carbon species.

At present, power battery mainly includes lithium iron phosphate battery, lithium manganate battery and lithium ternary battery. And lithium iron phosphate battery supports half of China's lithium ion battery material industry. What is the working principle of lithium iron phosphate battery?
