Among the three major trends in the development of lithium batteries, high energy density is currently the most urgent need. With the increasingly high requirements for range and capacity in electric vehicles, energy storage and other fields, the energy density of lithium batteries has become the focus of industrial development.

Energy storage batteries for wind energy, solar energy and other new energy sources: lead-acid batteries are energy storage batteries for wind energy, solar energy and other new energy generation systems, providing power when the power system is unstable. Other applications: lead-acid batteries also have applications in many other fields, such as
