According to public data, in 2023, China's cumulative exports of power batteries and other batteries reached 152.6 GWh, with power batteries accounting for 127.4 GWh (83.5% of total exports) and a year-on-year growth of 87.1%. In the first four months of 2024, cumulative exports reached 41.5 GWh, up 5.5% year-on-year, with power batteries contributing 37.1 GWh​​ (89.4% of exports).

Power batteries, designed to provide energy for vehicles, have stricter performance requirements compared to consumer electronics batteries. They demand high standards in power output, energy density, and cycle life​​, resulting in higher manufacturing costs.

Power batteries store and release energy through chemical reactions, supplying electricity to electric drivetrains. They are core components of new energy vehicles (NEVs). In hybrid vehicles, they can also collaborate with internal combustion engines to provide additional power. Advanced technologies like regenerative braking allow power batteries to recover and store kinetic energy generated during deceleration or braking, reducing energy waste.

Common types of power batteries include:

· Lithium-ion batteries: Widely used for their high energy density, long cycle life, lightweight design, and eco-friendliness.

· Nickel-metal hydride batteries: Higher energy density than lead-acid batteries, with reliable cycle life, often used in hybrids.

· Lead-acid batteries: The earliest type for EVs, but limited by low energy density and short cycle life.

With the continuous expansion of the New Energy Vehicle market, the power battery industry has grown steadily.
