What are the characteristics of ternary lithium batteries and lithium iron phosphate batteries? What are their advantages and disadvantages?

Lithium-ion battery is composed of anode material, cathode material, separator and electrolyte, in which the cost of anode material reaches 30%, which is also the key to improve battery performance at present. According to the different materials used, it can be divided into six types: lithium titanate, lithium cobaltate, lithium manganate, lithium ferrous phosphate, nickel cobalt manganese and nickel cobalt aluminum, of which the latter two are the famous ternary lithium batteries, also known as ternary polymer batteries.

Insiders pointed out that the performance indicators of power batteries mainly include five dimensions: energy storage density, cycle life, charging speed, high and low temperature resistance and safety, among which energy storage density and safety are two major requirements. Lithium titanate battery and lithium manganate battery were abandoned due to low energy storage density, while lithium cobalt oxide battery was shelved due to poor safety, leaving lithium iron phosphate battery and ternary lithium battery to enter the mainstream market, which were applied to passenger car market and passenger car market respectively.
