Example Embodiment

[0013] The present invention will be further described below in conjunction with embodiments.

[0014] Such as figure 1 As shown, a non-welded secondary battery includes a battery casing 1, a plurality of pole pieces 4 installed in the internal space of the battery casing, a diaphragm 3 installed between the pole pieces 4, a plurality of pole pieces leading out of the base tape 5, and two of the battery Polarity lead-out ends 8 and 9 are provided on the terminals. The polarity lead-out end 8 is the positive lead-out end, the polarity lead-out end 9 is the negative lead-out end, and the polarity lead-out ends 8, 9 are provided with a slot hole, and the bolts 7 are respectively installed in the two The end slot hole is connected and fixed by a fixed shaft 10 installed inside the battery. Both ends of the fixed shaft 10 are provided with screw holes matching with the bolt 7; the polarity leading ends 8, 9 are fixed by the bolt 7 and the fixed shaft 10. Tighten the polarity lead-out ...

Abstract

The invention relates to a non-welded secondary battery comprising a battery housing (1), a plurality of pole plates (4) arranged in the inner space of the battery housing, and a plurality of pole plate out-leading basebands (5). Polarity out-leading terminals (8) and (9) are arranged on two ends of the battery. A slot is arranged on each of the polarity out-leading terminals (8) and (9). Bolts (7) are respectively arranged in the slots on the two ends, and are connected and fixed through a fixing shaft (10) arranged in the battery. Two ends of the fixing shaft (10) are provided with bolt holes matching the bolts (7). The pole plate out-leading basebands (5) are respectively pressed against the polarity out-leading terminals (8) and (9). According to the invention, the positive and negative poles are directly connected with a pole set, such that battery internal resistance is greatly reduced, and battery internal heat out-leading speed is effectively improved, especially during large-current charging and discharging.

Description

technical field [0001] The present invention relates to a non-welded secondary battery. Background technique [0002] At present, the pole piece and the positive and negative terminals (especially the positive pole) of the secondary battery are generally connected by tabs, and the connection between the tab and the positive and negative terminals and the pole piece is generally realized by spot welding or laser welding. On the one hand, some parts that are not effectively welded during mass production will produce high internal resistance, which will affect the consistency of the battery; The internal resistance of the battery is greatly increased, and at the same time, the heat conduction speed of the internal heat of the battery is reduced, especially when charging and discharging with a large current. The tabs inside the battery are connected to the positive and negative terminals by welding, such as spot welding, wire welding, surface welding or laser welding. Due to t...
