Compared with lead-acid and nickel-chromium batteries, lithium iron phosphate battery’s pollution is very small, but for the environment, chemicals are still harmful. However, despite this, the synthesis and preparation of each material is difficult, and the stability is low, and there are still problems to be solved as practical materials.Īccording to the composition of the lithium battery, lithium iron phosphate in the positive electrode material does not contain heavy metals and basically has no pollution, while lithium manganese, ternary lithium, and lithium cobalt have heavy metal elements (manganese, cobalt, nickel) and have heavy metal pollution. Although the voltage is slightly lower than that of cobalt-based and manganese-based, it can reduce manufacturing costs. At present, most of the ternary lithium-ion batteries have a high proportion of nickel.
The ternary lithium-ion battery is a battery made of three materials, cobalt, nickel, and manganese, in order to reduce the amount of cobalt used. But the voltage is lower than other Lithium-ion batteries. The advantage of the iron phosphate lithium-ion battery is that it is difficult to damage the internal heating structure, has high safety, and uses iron as the raw material, so the manufacturing cost is lower than that of the manganese lithium-ion battery. Use lithium iron phosphate for the positive electrode. The disadvantage is that manganese may melt into the electrolyte during charging and discharging, shortening the life of the battery. The advantage is that the voltage can be similar to that of cobalt lithium-ion batteries, and the manufacturing cost is cheap. Use lithium manganate for the positive electrode. But because cobalt is a rare metal and expensive, it is hardly used in auto parts. Lithium cobaltate is relatively easy to synthesize and easy to use, so the earliest mass production of lithium-ion batteries is lithium-cobaltate batteries. Use Lithium cobaltate for the positive electrode.
