Disclosed are a conductive hot melt adhesive, a conductive insulating tape, and a battery, where the conductive hot melt adhesive includes a matrix and a conductive filler. A Vicat softening temperature of the conductive hot melt adhesive ranges from 60? C. to 130? C., and the conductive hot melt adhesive is solid in a first state and may soften and flow in a second state. The conductive hot melt adhesive is disposed between a positive electrode component and a negative electrode component of a battery. When a temperature is lower than the Vicat softening temperature of the conductive hot melt adhesive, the positive and negative electrode components cannot be conducted via the conductive hot melt adhesive; when the temperature is higher than the Vicat softening temperature, the conductive hot melt adhesive softens and flows, thereby conducting the positive and negative electrode components.

A braided thermoplastic ribbon is disclosed having fully impregnated filaments. The ribbon is formed by a thermoplastic prepreg having a plurality of continuous fibers that are substantially oriented in a longitudinal direction, the continuous fibers constituting from about 30 wt. % to about 40 wt. % of the prepreg, a first resinous matrix that contains a first set of one or more thermoplastic polymers and within which the continuous fibers are embedded, wherein the thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg, and a second resinous matrix that contains a second set of one or more thermoplastic polymers, wherein the second set of thermoplastic polymers constitute from about 30 wt. % to about 40 wt. % of the prepreg.
