Does lithium iron phosphate battery count cobalt free battery? What is a cobalt-free battery? Cobalt is a chemical element whose chemical symbol is Co. The pure element is a hard, shiny silver-gray metal. Read More »

Lithium iron phosphate​ has an olivine structure and is densely packed hexagonally (slightly twisted). LiFePO4 consists of FeO6 octahedron and PO4 tetrahedron to form a spatial skeleton. P occupies the tetrahedron position, while Fe and Li fill the octahedron gap. Fe occupies the coangular octahedron position, and Li occupies the coedal octahedron position. Read More »

LiLithium iron phosphate​ battery is a lithium ion battery which uses lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of single cell is 3.2V and the cut-off voltage of charge is 3.6V~3.65V. There are four main production materials of lithium iron phosphate battery: anode material, anode material, electrolyte and diaphragm. Read More »

In terms of power lithium battery, in terms of passenger cars, foreign countries take modified lithium manganate and ternary lithium battery as the main materials. In China, lithium iron phosphate is mainly used as the main material, but due to the low energy density of lithium iron phosphate, the current trend to ternary lithium battery. Read More »

Lithium battery materials are mainly composed of cathode materials, cathode materials, diaphragm and electrolyte, in addition to packaging and other parts. Lithium battery materials mainly consist of: anode materials, anode materials, diaphragm, electrolyte. Read More »

The competition of automobile power battery fluctuates several times under the big stick of new energy financial subsidy policy. First ternary lithium batteries knocked lithium iron phosphate batteries out of the "iron throne", and now it is the turn of lithium iron phosphate​ batteries, ternary lithium batteries in the underdog.
