What are the materials used in new energy power batteries?
1 Answers
New energy power battery materials mainly include cathode materials, anode materials, electrolytes, and separators. Below is relevant information about new energy power batteries: 1. Introduction to new energy power batteries: The power batteries used in new energy vehicles are lithium-ion batteries, which can be structurally divided into cathode materials, anode materials, battery separators, electrolytes, and other components. From the perspective of cathode materials, new energy vehicle power batteries can be broadly classified into two types: lithium iron phosphate (LFP) batteries and ternary lithium batteries. 2. Relevant information about new energy power battery materials: Among the costs of power batteries, cathode materials account for the largest proportion, reaching 28.27%. The cost of cathode materials is primarily composed of lithium carbonate and various corresponding precursor materials. Anode materials account for 6.85% of the power battery cost, and the main resource required for anode material manufacturing is graphite, with the largest application field of graphite resources being steel smelting. Electrolytes are mainly composed of solutes (lithium hexafluorophosphate), solvents, and additives, with the preparation materials for lithium hexafluorophosphate primarily being lithium carbonate and corresponding fluorine products. Different power battery products have significant differences in the usage of separator materials. Taking lithium iron phosphate batteries as an example, separators account for 7.67% of the battery manufacturing cost.
