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.

Lithium ion batteries have been widely used in notebook computers, video cameras, mobile communications and other portable appliances due to their unique performance advantages. At present, the large capacity lithium ion battery developed has been put into trial use in electric vehicles, and is expected to become one of the main power sources of electric vehicles in the 21st century, and be applied in artificial satellites, aerospace, energy storage and other fields. So, what are the main advantages of lithium batteries for electric vehicles?

The power recovery decision-making consultation salon co sponsored by the Beijing Association for Science and Technology and the Literature and Information Center of the Chinese Academy of Sciences was held in Beijing Green Space Center yesterday. Fei Weiyang, academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of pure electric drive has made great progress, and the core technology of electric vehicles represented by lithium ion has made a major breakthrough. However, the massive application of lithium batteries will also lead to the retirement of a large number of lithium batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for lithium battery recycling to achieve safe and efficient disassembly and overall recovery of valuable metals and prevent secondary pollution.

Instead of a set time in months, lithium polymer (Li-ion) batteries are rated for charge cycles. This means a full discharge and recharge cycle counts as one unit. Here's a breakdown of how long a Li-ion battery might last:
