Power Lithium-ion Batteries vs. Capacity Batteries: Relationship and Differences

Power batteries and capacity batteries both belong to the lithium-ion family. The core difference is design orientation: power batteries emphasize high-rate discharge and instantaneous power output, while capacity batteries emphasize high energy density and stable long-duration supply. They differ noticeably in cathode material, electrode coating thickness, separator and electrolyte formulation.

Understanding this distinction helps customers clarify their own requirements: scenarios dominated by power surges (power tools, jump starters) should prioritize power-type cells, while scenarios focused on range and storage duration (residential storage, telecom backup) should choose capacity-type cells.
