Electrode tab strucuture and battery

The present application provides an electrode tab structure and a battery, the electrode tab structure includes: an electrode tab substrate; a current collector connected with the electrode tab substrate, a largest thickness after the electrode tab substrate being welded with the current collector is less than or equal to 1.5 times of a sum of a thickness of the electrode tab substrate and a thickness of the current collector. In the present application, the thickness of the electrode tab structure is suitably limited with respect to the sum of the thickness of the electrode tab substrate and the current collector, which avoids defect of too large welding resistance caused by too large thickness of the electrode tab structure, so as to improve internal symmetry of the cell, increase the reliability of the electrode tab structure, and avoid from deforming, which thereby improving the overall performance of the battery.. ...

Cathode sheet and lithium ion electric roll using the same

A wound bare electric roll includes a cathode sheet, an anode sheet and a separator, the separator being arranged between the cathode sheet and the anode sheet. The cathode sheet has an end and an anti-puncture cushion arranged on a tail exposed zone at the end of the cathode sheet. ... Dongguan Amperex Technology Limited

Secondary battery and method for manufacturing the same

The embodiment of the present application relates to the field of li-ion battery and, in particular, to a secondary battery. The secondary battery includes a cell, a safety component fixed on the cell and thermal conductive adhesive provided between the cell and the safety component, the thermal conductive adhesive contains at least one of hot melt adhesive, silica gel binder or epoxy resin binder, and thermal conductive filling material. ... Dongguan Amperex Technology Limited

Thermal conductive adhesive and secondary battery containing the same

The embodiment of the present application relates to the field of li-ion battery and, in particular, to a thermal conductive adhesive and a secondary battery containing the thermal conductive adhesive. The thermal conductive adhesive is prepared through adding thermal conductive filling material in the hot melt adhesive system, which performs good thermal conductivity and adhering property, and can stably adhere the safety component with the cell, meanwhile transferring, via the thermal conductive adhesive, heat of the cell to the safety component rapidly, so that the safety component cuts off the circuit to protect the cell during overcharge; the thermal conductive adhesive has high initial viscosity, which increases good contact between the protection device and the cell through the adhesion, thereby reduces situations that the thermal conductive adhesive is separated from the cell due to inflation and deformation of the cell.. ... Dongguan Amperex Technology Limited

Li-ion battery electrode piece

The present application relates to a li-ion battery electrode piece, including an electrode piece substrate, a blank foil and an adhesive piece, the blank foil is arranged at one end of the electrode piece substrate along the length direction of the electrode piece substrate, one end of the blank foil away from the electrode piece substrate has a right-angle area, the adhesive piece is adhered at the right-angle area. The li-ion battery electrode piece provided by the present application, through adhering an adhesive piece on the blank foil, avoids the end of the electrode piece from being deformed and folded, and improves the phenomenon of convex in battery core appearance and bad streak.. ... Dongguan Amperex Technology Limited

Insulating tape and li-ion battery adopting the same

The present application relates to the field of energy storage devices and, particularly, relates to an insulating tape and a li-ion battery adopting the same.
