Application of INR 21700 Cells
Electric Vehicles (EVs): such as electric cars, electric bicycles, electric scooters, etc., provide strong power support and longer driving range.
Portable Electronics: such as laptops, smart wearable devices, mobile power supplies, etc., ensure long-term use without frequent charging.
Energy Storage Systems (ESS): used for home or industrial energy storage to improve energy efficiency and reliability.
Power Tools: such as electric drills, lawn mowers, vacuum cleaners, etc., provide efficient and long-lasting power output.
Medical Devices: such as portable medical monitoring equipment, ventilators, etc., ensure stable operation and safety of equipment.
High Capacity 21700 Battery excels in capacity and safety:
Capacity:
Energy density: High energy density means more energy can be stored in the same volume, providing longer battery life.
Cycle life: After more than 1,000 charge and discharge cycles, it can still maintain a high capacity retention rate, ensuring stable performance in long-term use.
Safety:
Built-in protection circuit: Including overcharge protection, over-discharge protection, short circuit protection and temperature protection, effectively preventing safety problems caused by improper use of the battery.
Material selection: High-quality positive and negative electrode materials and electrolytes are used to reduce the risk of internal short circuits and thermal runaway.
Strict quality control: International standards are strictly implemented during the production process, and multiple safety certifications (such as PSE, CB, BIS, CE, TUV, IEC 62133-2, RoHS 2.0, UL2580, etc.) are passed to ensure the safety and reliability of the product.
Temperature management: Good thermal management design ensures that the battery can work normally under extreme temperature conditions and extend its service life.
A 21700 Lithium Power Battery is a type of lithium-ion rechargeable battery. The numbers "21700" refer to the battery's dimensions: it is 21mm in diameter and 70mm in length. 21700 batteries are commonly used in high-performance applications such as electric vehicles, power tools, and high-powered flashlights. They offer a higher capacity than 18650 batteries and are known for their high energy density, long lifespan, and relatively low self-discharge rate.
