The battery industry has already developed for about 220 years. The world - recognized first battery is the Voltaic Pile invented by the Italian physicist Alessandro Volta. Although the battery industry has developed for more than 200 years, our lithium - manganese pouch battery only began to develop in the early 21st century. So, how much do you know about the lithium - manganese pouch battery? Let's take a closer look at it today.
The lithium - manganese pouch battery uses manganese dioxide as the positive electrode material and lithium metal as the negative electrode material. The positive and negative electrodes are separated by a separator and wound into a cell. The cell is then side - sealed and top - sealed with an aluminum plastic film, and electrolyte is injected. After that, the battery undergoes discharging, aging, secondary vacuum - drawing, cutting, folding and sealing. According to customer requirements, red and black electrode wires are attached and the battery is marked. It is a primary non - rechargeable battery.
Characteristics of Lithium - Manganese Pouch Battery:
-
Stable Voltage: The nominal voltage of lithium - manganese pouch batteries is approximately 3.0v - 3.7v. Generally, the larger the discharge current and the smaller the load, the lower the actual output voltage.
-
High Energy Density: It provides more energy with a smaller volume or weight, significantly increasing the endurance. This leads to more stable energy output efficiency and enhanced user convenience.
-
Customizability: The customization of lithium - manganese pouch batteries is not only reflected in performance parameters and pouch shape, but also in safety and protection, as well as application scenarios.
-
Temperature Resistance: The operating temperature range of lithium - manganese pouch batteries is - 40℃ to 60℃. Even under extreme temperatures, the discharge efficiency and voltage can remain relatively stable.
The pouch design of lithium - manganese pouch batteries uses aluminum plastic film for heat - sealing packaging. It is flexible and less likely to explode. When the temperature is too high, the circuit will be blocked to prevent explosions. The use of a separator and winding method reduces the complexity and cost of the process, greatly enhancing the safety of the battery.
Lithium - manganese pouch batteries have a wide range of applications and are mainly used in smart meters, intelligent transportation, active electronic tags, credit cards, trackers, security and other scenarios.
Domestic manufacturers of lithium - manganese pouch batteries include Huizhou Yuchen New Energy Technology Co., Ltd., Wuhan Fuante Technology Co., Ltd., Hubei Ruiyi Times New Energy Technology Co., Ltd., etc.
