The invention relates to an asymmetric mixed pole plate same-direction
electrode type porous current collection disc type winding type storage battery. The winding type storage battery comprises a battery shell and a
battery cell. The winding type storage battery is characterized in that the
battery cell is a cylindrical body formed by a positive plate, a negative plate and a diaphragm through the winding of a battery core reel, the diaphragm is located between the positive plate and the negative plate, and a
positive current collection disc and a negative current collection disc are respectively arranged on the tops of two ends of the battery core; a lug, namely a positive continuous lug, having the same length with the positive plate is arranged on the top end of one side, close to the
positive current collection disc, of the positive plate, and a spiral groove, namely a positive plate clamping groove, is formed in the
positive current collection disc; a negative terminal is guided to the direction of a positive end of the battery through an
electrode terminal protecting sleeve arranged on the side surface of the battery shell; and the negative plate is a mixed
electrode,
metal oxide coating layers are distributed on the mixed electrode in a point manner, and substances of the
coating layers are
ruthenium oxide and the like. The winding type storage battery has the beneficial effects that by utilizing a special end surface current collection structure and the mixed electrode, the
current conduction capacity is effectively improved, and meanwhile, the battery has high-rate charging and discharging properties of a super-
capacitor.
