A battery top cover assembly structure includes a top cover sheet and an electrode column arranged thereon. The top cover sheet is provided with a mounting hole for mounting the electrode column. An insulating part and a plastic part are sleevedly arranged on the electrode column in sequence. The plastic part is embedded in a bottom of the mounting hole. A bottom of the electrode column is fixedly provided on a bottom surface of the plastic part.

A battery receptacle system for a rail-style battery pack that is useful for vibrating tools and devices includes multiple resilient members anchored in grooves of the battery receptacle's base. The grooves are positioned below arms that extend from the receptacle's opposing lateral walls. Between each arm and groove, a rail recess accepts rails on a cooperating rail-style battery pack. The resilient members are configured to extend into the rail recess and provide support and resistance against the battery pack's rails when it is engaged with the battery receptacle. The resilient members counteract any excess force and rapid movement caused by the vibrations of the power tool or device coupled to the battery receptacle and battery pack.

The battery provided in this application and having at least two ports is obtained by winding a first electrode and a second electrode that have a novel structure (for example, a plurality of tabs separately protrude from a first long side and a second long side of an electrode, and the tabs are disposed on a non-edge area). In addition, in the terminal device including the battery, the battery and another charging/discharging component may form at least two charging/discharging links, so that the terminal device can have a stronger fast charging capability, and heat dissipation pressure of each charging/discharging link can be relieved. Moreover, stress inside the battery is evenly distributed, so that interface deterioration of the electrode that is caused by stress unevenness can be alleviated. This effectively reduces a risk of shading and lithium plating generated in a cathode charging/discharging cycle, and improves performance of the battery.

A non-aqueous electrolyte secondary battery includes: an electrode assembly; a rectangular outer casing; a sealing plate; an electrode terminal on the sealing plate; a first current collector connected to the electrode terminal; a second current collector connected to the first current collector; and a tab group connected to the second current collector. The second current collector is a flat plate, and includes a fuse portion having a slit extending in a lateral direction of the flat plate. The tab group is connected to the second current collector at a position closer to one side in the lateral direction, and is bent at a connection portion with the second current collector such that the bent tab group extends parallel to the side wall. The fuse portion includes a portion with a large sectional area on the other side of the slit in the lateral direction.
