Embodiment Construction

[0013] Below in conjunction with embodiment the present invention is further described.

[0014] Such as figure 1 As shown, a non-welded secondary battery includes a battery case 1, a plurality of pole pieces 4 installed in the inner space of the battery case, a diaphragm 3 installed between the pole pieces 4, a number of pole pieces leading out basebands 5, two pole pieces of the battery Polarity lead-outs 8 and 9 are set at the terminals, wherein the polarity lead-out 8 is the positive lead-out, the polarity lead-out 9 is the negative lead-out, a slot hole is set on the polarity lead-outs 8 and 9, and the bolts 7 are respectively installed on the two In the end slot hole, it is connected and fixed by the fixed shaft 10 installed inside the battery. The two ends of the fixed shaft 10 are provided with screw holes that cooperate with the bolt 7; the polarity lead-out ends 8 and 9 are fixed by the bolt 7 and the fixed shaft 10. Tighten the polarity lead-out ends 8, 9, and at t...

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...
