Lithium-ion batteries are secondary battery products with large development potential. According to the “China Lithium-ion Battery Industry Development White Paper (2023)” released by EV Tank, the overall global lithium-ion battery shipments will be 957.7GWh in 2022, representing a significant year-on-year growth of 70.3%. Compared with traditional secondary batteries such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and other traditional secondary batteries, lithium-ion batteries have the advantages of high operating voltage, high specific energy, small self-discharge, long cycle life, no memory effect, good cycling performance, and long service life, etc., and they have been widely used in the field of consumer electronics, and are mainly used in the field of consumer electronics in the field of tablet PCs, laptops, cellular phones, electronic nebulizers, and power tools. The global small lithium-ion battery market revenue reached RMB 151.189 billion in 2022, and the Chinese small lithium-ion battery market size reached RMB 70.484 billion. According to the development environment of small lithium-ion battery industry and the overall development trend of the industry, the small lithium-ion battery market is expected to reach a compound annual growth rate of about 8.81%, which foresees that the global small lithium-ion battery market size will reach 250.988 billion yuan in 2028.
