Abstract

The invention discloses a button cell with a base. The button cell with the base comprises a negative electrode cover, a positive electrode shell, a sealing ring, a positive electrode, a diaphragm, anegative electrode and electrolyte; the sealing ring is in sealed connection with the negative electrode cover and the positive electrode shell; furthermore, the negative electrode cover and the positive electrode shell form a sealing cavity; the positive electrode, the diaphragm, the negative electrode and the electrolyte are arranged in the sealing cavity; the button cell further comprises an energy gathering ring arranged in the positive electrode shell; the energy gathering ring comprises an outer annular wall, an inner annular wall and a top wall used for connecting the outer annular wallto the inner annular wall; the outer annular wall, the inner annular wall and the top wall form an annular cavity; the top wall and the sealing ring are in abutting joint; a first through hole, through which electrolyte and / or gas go / goes in and out, is arranged on the annular cavity; and the positive electrode part is positioned in the inner ring of the energy gathering ring. According to the button cell with the base, because the energy gathering ring with the annular cavity is arranged, the capacity and the discharging power of the cell are improved; the working temperature range is expanded; the global stability, the storage property, the consistency and the leakproof property of the cell are improved; and the service life of the cell is prolonged.

Description

technical field [0001] The invention relates to the field of button batteries, in particular to a button battery with a base. Background technique [0002] Button batteries are widely used as power sources in various miniature electronic products due to their light weight and small size. Usually, a button battery includes a positive electrode casing, a negative electrode cover, and a battery cell and electrolyte in a sealed cavity formed between the positive electrode casing and the negative electrode cover. Batteries. However, relative displacement and liquid leakage between the positive electrode and the positive electrode casing usually occur during the packaging process of the positive electrode casing and the negative electrode cover of the above-mentioned button battery, which not only reduces the battery life Overall stability and leak-proof performance, and shortened battery life. Contents of the invention [0003] In view of this, the embodiment of the present ...
