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. The thermal conductive adhesive in the secondary battery performs good thermal conductivity and adhering property, which 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, thereby avoid situations that the thermal conductive adhesive is separated from the cell due to cell inflation and deformation.

Secondary battery and method for manufacturing the same

The present invention belongs to the technical field of lithium ion battery production equipment, and particularly relates to a double-folding device for softly-packaged lithium ion batteries, comprising a rack, and a loaded-material positioning mechanism, a primary folding mechanism and a secondary folding mechanism which are arranged on the rack in turn. A bonding layer arrangement mechanism is further provided between the primary folding mechanism and the secondary folding mechanism. In comparison to the prior art, in the present invention, by providing, between the primary folding mechanism and the secondary folding mechanism, a bonding layer arrangement mechanism which is configured as a mechanism capable of online monitoring the arrangement of a bonding layer and automatically adjusting the glue dispensing position and glue volume, the real-time adjustment of the dispensing position and volume of glue is realized.
