Features:
Rechargeable Lithium Ion(Li-ion) cells have a negative electrode(anode) made from lithium compounds.Lithium is a highly reactive material and is much lighter than the hydrogen-absorbing metal alloy of the NiMH negative electrode.This leads to higher gravimetric energy densities for the Li-ion cell.Cells can stay in storage for 12 months without requiring maintenance.The expected cycle life of a Li-ion in an application is about >1000 cycles.
Advantages:
1.Higher voltage,high capacity
2.Higher specific energy
3. Long cycle life about 1000+
4.Safety,no memory effect
5.Lower self-discharge,<3%/monthly
6.Fast charging,good discharge performance at high/low temperature
7.Clean and Green energy, no toxic material contained.
8.Can stay storage for 12 months without requiring maintenance.
Applicitions:
1. UPS,Solar,Wind,Mobile generator,Back up power
2.Solar power bank,Solar LED lighting,Solar street light
3.Electric Scooter/motorcycle, E-bike, Golf cart, E-motor, E-tour car, tricycle
4.Electric drill, electric saw, lawn mower and so on
5.Remote control cars, boat, aircraft, toys
6.Medical devices, equipment and portable equipment
7.Blutooth, GPS, Wearable device, Power supply, Wireless ,mobile phone & laptops and other digital products
