Abstract

The invention provides a battery cover plate assembly, a battery core, an assembling method of the battery core and connecting pieces. The battery cover plate assembly comprises a cover plate, a coverplate upper plastic, cover plate lower plastic and terminals, wherein terminal holes are respectively arranged on the cover plate upper plastic, the cover plate and the cover plate lower plastic, theterminals comprise terminal end plates and terminal bosss arranged on the terminal end plates, the terminal bosses of the terminals sequentially penetrate into the terminal holes of the cover plate upper plastic, the terminal holes of the cover plate and the terminal holes of the cover plate lower plastic, the terminal bosses of the terminals are provided with connecting sheet guide grooves for thconnecting sheets to pass through, and the connecting sheets wrap tabs on a roll core. The battery cover plate assembly is advantaged in that a utilization rate of the interior of the battery core inthe height direction can be improved, and then the energy density of the battery core is improved.

Description

technical field [0001] The present application relates to the field of lithium-ion battery equipment, in particular to a battery cover assembly and an assembly method thereof, a battery cell and an assembly method thereof, and a connecting piece applied to the battery cell and the battery cover assembly. Background technique [0002] With the rapid development of new energy battery technology, the penetration rate of new energy vehicles in the market is also gradually increasing. The most concerned issues about new energy vehicles are the mileage and the safety of electric vehicles. In response to the above problems, for power battery manufacturers, how to improve the safety characteristics of the battery cell and increase the energy density of the battery is the top priority. [0003] In the existing power battery design scheme, the connection between the inner winding core of the battery and the top cover terminal is mostly adopted by bending tabs and welding with connecti...
