product features
●pollution-free:lithium ion battery does not contain heavy metal pollutants such as cadmium, lead, mercury and so on.
●long cycle life: charge and discharge cycles are ordered more than 500 times (with 80% capacity remained)。
●low self-discharge: self-discharge less 10% per month.
●no memory effect:the state of charge before charge does not affect the discharge capacity.
●high energy density: the energy density of lithium battery is higher than that of lead-acid battery, nickel-cadmium battery and nickel-hydrogen battery. the volume capacity density oflithium battery is 320ah/l and the weight capacity density is 150ah/kg.
●high operating voltage: the average working voltage of single cell is 3.7v.
batterysafety
●external short circuit test:after fully charged, the battery is short-circuited by conductor with the resistance of less than 5 0mω; the battery does not cause fire orexplode.●pinpricking test:the battery should be fixed on the fixture of the safety device and beaten forcefully by the steel nail with the diameter of 2.5 mm, so that it is fullypenetrated; the battery leaks and generates heat; the battery does not cause fire or explode.
●thermal shock test:after fully charged, the battery is put into the oven and heated to 150℃at the rate of 5℃/min, which should bepreserved for 30 minutes; the battery bulges and generates heat; the battery does not cause fire or explode.●overcharge test:battery should be charged under the condition of 3cmagnification and 5v voltage; battery does not cause fire or explode.
