What is the history of silver oxide button battery?

Silver oxide button battery was first used commercially in the 1960's and mainly contributed to micro power supplies. The silver oxide battery, with silver oxide as the positive electrode and zinc as the negative electrode, has a very high energy-to-weight ratio, meaning that a battery of the same weight will contain much more energy. Silver oxide batteries can take the form of small buttons. Silver oxide button batteries are used in hearing aids, photographic applications, toys, medical devices, watches and other low power devices. Larger silver oxide batteries can be used for military applications including missiles, torpedoes, and submarines. It is worth noting that traditional silver oxide batteries are non-rechargeable and they have been replaced by others in many areas in recent years as the price of silver has increased.

What is the difference between silver oxide button battery and lithium battery?

Lithium battery is a type of battery that mainly consists of lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.

Silver oxide battery is made of silver oxide as the positive electrode, zinc metal powder as the negative electrode, and potassium hydroxide or sodium hydroxide as the electrolyte solution. Electricity is generated through the chemical interaction of zinc and silver oxide.

The lithium battery cell voltage is 3.7V, the resistance is small, the current is stable, the self-discharge rate is extremely low, and the discharge voltage is very smooth, which is generally used for small portable appliances or home appliances such as cell phones and computers.

Silver oxide battery has the advantages of smooth discharge and high energy to weight ratio, but because of the high cost of silver, it is generally used mainly as silver oxide button battery, or used in some specific occasions that require higher requirements and can withstand this high cost, such as some torpedoes or submarines.

What are the features of silver oxide button battery?

There are two series of silver oxide button battery, "SR××" and "SR××SW". The difference lies in the content of silver oxide in the battery: the "SR××" series has a low silver content, while the "SR××SW" series has a high silver content. In terms of battery performance, the main difference is that the time on the 1.5V discharge platform is significantly different, with the "SR××" series having a short discharge time; and the "SR××SW" series having a long discharge time, with about 90% of its life being spent on the 1.5V platform. 1.5V platform or more.
