Abstract:

A wound cell (1) is formed by winding start ends of a first diaphragm (30), a first electrode plate (10), a second diaphragm (40), and a second electrode plate (20). An outermost periphery of the second electrode plate (20) comprises a second single-sided coating region (22). The surface of the single-sided coating region (22) facing toward the center of the wound cell is a second air current collector region (23) not coated with an active material. The portion of the first electrode plate (10) opposite to the second air current collector region (23) comprises a first single-sided coating region (12). The surface of the first single-sided coating region (12) facing away from the center of the wound cell is a first air current collector region (13) not coated with the active material. A finish end of the first electrode plate comprises a first air foil region (11). The portion of the second electrode plate (20) opposite to the first air foil region (11) comprises a second air foil region (21). The start end of the first air foil region (11) and the start end of the second single-sided coating region (22) are located at two opposite sides of the cell in the thickness direction. Armors are formed on both plane of the cell, so that the safety of the cell is improved.
