Comparison of performance and cost of lithium-ion batteries and lead-acid batteries

　　Lithium iron phosphate battery is the preferred choice for lead-acid battery replacement, which is the general trend.

　　Global lead-acid battery shipments exceed 500GWh per year. In 2019, China’s lead-acid battery output was 202.5GWh. The downstream lead-acid batteries are mainly used for low-speed vehicles such as electric bicycles, automobile starting power supplies and other portable devices. At present, light-power batteries account for 33%, car start-up batteries account for 45%, and industrial batteries account for 22%. At present, lithium iron phosphate is mainly used in the light power market represented by electric two-wheelers and some industrial fields, replacing normal Accelerate the progress, and the penetration rate is expected to reach 40-50% next year.
