Feature of RJ lithium battery


(1) High operating voltage

Taking graphite as the negative electrode and selecting a suitable electrolyte can make the lithium battery have a higher working voltage, which is much higher than that of the aqueous system battery.

(2) Large specific capacity

(3) High energy density

(4) Good safety performance and long cycle life

(5) Small self-discharge rate

The lithium battery adopts a non-aqueous electrolyte system, so that the electrode electrode active materials in different charged states are in a relatively stable state, and thus have a low self-discharge rate.

(6) Clean and pollution free

Lithium batteries do not contain toxic substances such as lead, blessings, mercury, etc., and no gas is released during use, and it does not pollute the environment.

(7) High current efficiency

Unlike any secondary battery of an aqueous solution system in the past, a lithium battery does not generate gas during normal charging and discharging, and the current efficiency is close to 100%. This property is particularly suitable for use as a battery pack for power storage and conversion.



RJ produce LiFePO4 Prismatic Battery Cell from scratch with various capacity, from 10ah up to 320ah single cells. Perfectly for solar energy storage, electrice golf cart, electric forklift, robotic system AGV, electric vehicles, UPS etc.

RJ battery features its long lifecycles which reach 6000cycles, and we offer 5years Warranty up to 10years, RJ LiFePO4 Lithium Iron Phosphate battery cells also has excellent perfermance in discharge and charge. We are looking for long term business partner all over the world, we will be very supportive on price to help develop your local market on mutual benefit. contact us for a latest pricelist now!
