LG battery is a ternary cathode material. Generally, the cathode material uses lithium-nickel-cobalt manganate(Li(NiCoMn)O2) or lithium-nickel aluminate ternary cathode material. Cathode composite materials are made of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs.
LG batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in metallic form. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Performance analysis:
It is a relatively balanced material in terms of capacity and safety. Its cycle performance is better than cthey are normal lithium cobalt oxide. For technical reasons, its nominal value. the voltage is only 3.5-3.6V. There are limitations in the scope of use. With the continuous improvement of the formula and the improvement of the structure, the rated voltage of the battery has reached 3.7V and the capacity has reached or exceeded the value. level of lithium cobalt oxide batteries.
The battery using lithium iron phosphate as cathode material has a long charge and discharge cycle life, but its disadvantages are that there are large deviations in density energy, high and low temperature performance and charge and discharge rate. characteristics and the production cost is high.
