Energy storage technology batteries belong to the type of lead-acid batteries, which are the cheaper metal materials in rechargeable battery materials. In China, electric forklifts widely use this type of lead-acid battery as the material, with electric forklifts with traction belts as the driving force. Traditional energy storage technology batteries and nickel cadmium batteries have low energy density and both contain excessive heavy metals (lead, cadmium). Lead acid battery batteries are not suitable for deep battery charging, and nickel cadmium batteries have significant memory. Therefore, traditional rechargeable batteries are difficult to consider the regulations of various power consuming equipment with rapid development trends; Energy storage technology batteries are relatively early materials, and currently there is no cheaper alternative available. Lithium metal has the most negative electrode potential and a relatively small atomic mass. Therefore, using lithium as the negative stage of rechargeable batteries is expected to achieve the maximum working voltage and high energy density. In addition, it also has the characteristic of low lithium battery life rate, with an annual lithium battery life rate of less than 2%.
