Description
The LiMn2O4 Li Ion Cell is a rechargeable lithium-ion battery with a positive electrode material of lithium manganese oxide (LiMn2O4), used in applications such as electric vehicles, power tools, and consumer electronics. Its anode is usually made of graphite, and the electrolyte is a lithium salt in an organic solvent. The nominal voltage of it is 3.7v, the nominal capacity is 7500mAh, and it has a high battery density, so it can achieve multiple charge/discharge cycles. It can store large amounts of electricity and provide high energy output and long-lasting power for your devices as a portable backup power source. However, like all lithium-ion batteries, it is prone to overheating and will decompose at high temperatures of 250-300°C.
Features
1. Safety: This LiMn2O4 Li Ion Cell is equipped with current monitoring and protection functions, which can provide current, voltage and short-circuit protection in real time. It can also determine the status of the device and issue an alarm when an abnormality is detected to protect the safety of users and devices.
2. Portable: This battery has a compact structure and is very easy to move and transport. Its volume is 2/3 of the volume of lead-acid batteries, and its weight is about 1/3 of the weight of lead-acid batteries.
3. Good temperature resistance: The battery is made of lithium manganate chemical composition and can withstand operating temperatures of -20~60°C, ensuring stability in different environments and avoiding lagging.
4. Durable: Its average lifespan is about 1.5 times longer than that of lead-acid batteries. The power supply is stable during use, allowing thousands of cycles during use, and can provide power for equipment for a long time.
