CELL WINDING PROCESS, CELL WINDING DEVICE, CELL, BATTERY, AND POWER CONSUMING DEVICE

Abstract

A cell winding process, a cell winding device, a cell, a battery, and a power consuming device. A heating portion is arranged to heat a separator layer, such that a PCS polymer of the separator layer is melted at a high temperature, to bond a cathode electrode plate to an anode electrode plate, and the cathode electrode plate is thus closely bonded and fixed to the anode electrode plate, thereby preventing the electrode plates from being retracted due to stress release after winding, which otherwise results in a gap.
