Which power lithium battery material is better?

Batteries, as the source of power for electric vehicles, are naturally one of the most important components. The battery life, charging and discharging and other uses of electric vehicles are also inextricably linked to the performance of the battery. At present, domestic power lithium-ion batteries are mainly divided into two factions, which are divided into lithium iron phosphate and ternary materials based on the difference of cathode materials. Although both are secondary batteries, they can be used repeatedly for charging and discharging, but due to the difference in materials, there is still a big difference in the performance reflected in the use level. The global layout of the power lithium-ion battery industry is clear, and my country's market will become an important area for competition, but the level of internationalization of my country's battery processing companies is relatively low. With the expansion of the industrial scale, battery companies’ demand for upstream resources has increased sharply. The company’s warfare has stretched from the competition for supporting customers to upstream materials and resources. Lithium, nickel, and cobalt resources around the world are very hot, and they are the first to deploy power lithium ion. Battery companies will have the initiative. Lithium metal battery: Lithium metal battery is generally a battery that uses manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and uses a non-aqueous electrolyte solution. Lithium batteries: Lithium batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte. Although the energy density of lithium metal batteries is high, theoretically it can reach 3860 watts/kg. However, due to its insufficient stability and inability to charge, it cannot be used as a power lithium-ion battery for repeated use. The lithium battery has been developed as an important power lithium-ion battery due to its ability to be recharged repeatedly. However, because of its combination of different elements, the composition of the cathode material has very different properties in various aspects, which has led to increased disputes over the cathode material route in the industry, so both sides have their own advantages and disadvantages.
