Background
The alkaline zinc-manganese battery has the characteristics of wide application range as a daily consumer product, and the discharge performance and the storage performance of the alkaline zinc-manganese battery are particularly emphasized by manufacturers and consumers. The cylindrical alkaline zinc-manganese dioxide battery is composed of a steel shell, an anode ring, a diaphragm tube, a cathode zinc gel, a current collector and the like. In the prior art, a diaphragm tube is generally rolled into a tube by special fiber paper, one end of the paper tube is folded and ironed, and then the paper tube is inserted into a central hole of a positive electrode ring in a battery body. The other end face of the paper tube abuts against a seal ring attached to the current collector of the battery when the battery is sealed. After alkaline electrolyte is injected into the diaphragm tube and cathode zinc gel is injected into the diaphragm tube, the diaphragm tube wall plays the role of an ion channel between the anode and the cathode of the battery in the electrochemical reaction process of the battery, and the direct conduction of electrons between the anode and the cathode is blocked. During electrochemical reaction in the battery, ions between the positive electrode and the negative electrode can be efficiently transferred in the diaphragm tube wall, and direct conduction of electrons between the positive electrode and the negative electrode can be reliably blocked, so that the direct conduction is an important guarantee for obtaining good discharge performance and storage performance of the battery.
The above structure has the disadvantage that since the electrolyte absorbed and stored in the diaphragm tube contains charged particles, and since one end of the diaphragm tube, which is attached to the sealing ring, is not sealed, the charged particles can move mutually between the positive electrode and the negative electrode of the battery along the inner and outer wall surfaces of the diaphragm tube and the opening end surface of the diaphragm tube due to brownian motion, which is equivalent to that a micro electronic path is formed between the positive electrode and the negative electrode inside and outside the diaphragm tube of the battery. The long-term action will reduce the capacity of the battery and affect the storage performance of the battery. This phenomenon of electron drift across with particle brownian motion is exacerbated by the increased degree of swelling of the electrolyte on the membrane tube.
It is known that the content of electrolyte has an important influence on the discharge performance of the battery, and higher electrolyte content in a certain range can have better high-current discharge performance. However, in the existing structure, the content of the electrolyte in the battery must be strictly controlled, otherwise, the quality problems of battery leakage, poor storage performance and the like are easily caused. It is thought that if the drift of charged particles between the inner and outer walls of the diaphragm tube can be blocked, it will help to solve such a conflict, which is of practical significance in providing the overall performance of the battery.
