The low temperature in button cell is somewhat ineffective.

The low temperature in button cell is 40 degrees below zero. The performance of the battery is closely related to the ambient temperature. The discharge capacity and discharge capacity will drop sharply at low temperature, and will drop when heated, and the characteristics of steel shell button battery will weaken when cold, which greatly hinders the application of battery in cold and high temperature environment.

Zinc-air button battery is special, and its only civilian market is high-grade cochlear implant and electronic hearing aid. This battery is a primary battery with zinc as the negative electrode and oxygen in the air as the positive depolarizer. Because the positive active material is stored in the atmosphere, it is inexhaustible, so this battery has the characteristics of high energy ratio and is the first series of chemical power supply.

Its capacity is three to ten times that of other batteries, and it is the highest among all practical battery systems. This battery also has the advantages of very stable working voltage and very low noise. It is the best power supply for advanced hearing AIDS of tympanic membrane, inner ear and ear canal. In addition, it also has the advantages of energy saving, material saving, environmental protection and ecological pollution-free.
