Introducing CR1225: The Versatile Lithium Manganese Button Cell

Among a variety of batteries, the CR1225 lithium battery stands out as a reliable and efficient energy source for a wide range of electronic devices. And in this part, we will delve into the intricacies of the CR1225 battery, exploring its basic structure, working principles, features, usual applications, and market presence.

Overview Of The Construction Of CR1225

CR1225, also known as the Lithium Manganese Button Cell, is a member of the 3V lithium-manganese battery family, whose name is derived from its physical specifications: a diameter of 12.5mm and a height of 2.5mm.

This portable and compact size makes it become an ideal opportunity for space-constrained devices, where every millimeter counts. Moreover, the CR1225 batteries will boast a nominal voltage of 3.0V, which is double that of standard alkaline batteries, ensuring a robust power supply for various electronic components.

CR1225's construction is meticulously designed for optimal performance and safety for different types of electronic devices. Its exterior is crafted from stainless steel, which is specifically chosen for its durability and corrosion resistance. And this kind of material not only protects the internal components but also contributes to the battery's overall structural integrity.

At the heart of the CR1225 lies its electro-chemical system, comprising a stable manganese dioxide (MnO₂) cathode, a high-energy lithium metal anode, and an electrolyte composed of lithium salts dissolved in a mixture of organic solvents, such as propylene carbonate (PC), dimethyl carbonate (DMC), and dioxolane (DOL). This configuration enables CR1225 batteries to deliver consistent power over extended periods, together with a low self-discharge rate.

Working Principles Of CR1225 Battery

CR1225 button battery has compact structure and excellent design. Its shell is made of stainless steel strip special for lithium batteries, which not only is equipped with mechanical strength that can resist corrosion, but also effectively protects the internal composition of the battery from the external harsh environment. The cathode material of the battery uses manganese dioxide (MnO₂), which is extremely stable in chemical properties. This kind of material not only ensures the high energy density,  but also extends the service life of the battery. Then, as the negative electrode uses lithium metal (Li), which provides strong power support for the battery, it enables the CR1225 lithium battery to offer high specific energy and lightweight characteristics.

The electrolyte is an important component of the battery interior. And the CR1225 series all use lithium battery electrolytes. The main component is lithium perchlorate (LiClO₄). And the solvent is a mixture of Propylene carbonate (PC), DMC and dioxopentyclic acid (DOL). The electrolytic liquid system not only has good electrical conductivity, but also can effectively inhibit the side reaction inside the battery in order to ensure the stable operation.

Characteristics Of CR1225 Battery

One of the most notable features of CR1225 battery is its width of operating temperature range, which can span from -20°C to 60°C. While most manufacturers recommend using the bottom battery within a narrower range of 5°C to 60°C for optimal performance, some advanced CR1225 variants, can operate even in sub-zero temperatures down to -40°C. And this versatility makes CR1225 lithium battery suitable for harsh working environment and applications.

The capacity of CR1225 rates at 50mAh, which may seem modest compared to other larger batteries, but it is sufficient for powering small electrical devices for extended periods. And the CR1225 lithium battery can typically deliver a continuous current of up to 1mA and a maximum pulse current of 5mA, allowing it to meet different demands of various electronic components without overheating or draining too quickly.

For a more precise and clear explanation of the basic features of the CR1225 battery, here is a table for your consideration.

Features	Functions
High voltage	The CR1225 battery has a nominal voltage of 3.0V, which is twice that of normal dry batteries, making it more suitable for many electrical devices that require high voltage drives.
Longer service life	Due to the application of chemically stable materials, the annual self-discharge rate of the battery is less than 2%. As the storage life is longer, the battery can maintain a good state of electricity even if it is not used for a long time.
Wider temperature range	The CR1225 battery has a wide operating temperature range from -20℃ to 60℃. It can work normally in a harsh industrial environment. Although in practical applications, the performance of some brands of batteries will be reduced at a temperature below 5 ° C, CR1225 batteries produced by some high-end brands such as Panasonic can even be powered down at a low temperature of minus 40 ° C, greatly expanding the application scenarios of the battery.
Safety	CR1225 battery applies a reasonable sealing structure and materials. Correspondingly, it has good air tightness, and can effectively prevent electrolyte leakage and internal short circuit and other security risks. At the same time, the battery is specially designed, and the production process of CR1225 is strictly complied with the relevant safety standards, ensuring the safety of users and the environment.
Higher energy density	Due to the use of specific energy metal lithium as negative electrode composition, the CR1225 battery has a higher energy density than other versions of batteries and can store more energy in a smaller volume to meet the needs of various portable devices for longer services.
