High voltage Single battery operating voltage up to 3.7-3.8V (lithium iron phosphate, 3.2V), Ni-Cd, Ni-H battery 3 times times Energy Currently can achieve effective energy for 555Wh/kg or so, that material can reach more than 150mAh/g capacity (3--4 times Ni-Cd,2--3 times Ni-MH), is close to the theoretical value of about 88%. Long cycle life Can reach more than 500 times, even more than 1000 times, can reach more than 2000 of lithium iron phosphate. For small current discharge of electrical, battery life, double electric competition. Good safety performance No pollution-, no memory effect. as Li-ion predecessor of lithium battery, for metal lithium easy formed branch Crystal occurred short-circuit, reduced has its application field: Li-ion in the not containing CD, and lead, and mercury, on environment has pollution of elements: part process (as sintering type) of Ni-Cd battery exists of a big ills for "memory effect", serious bound battery of using, but Li-ion fundamental not exists this aspects of problem. Low self discharge Fully charged Li-ion storage at room temperature about 1 month after the self discharge rate of 2%, significantly lower than Ni-Cd 25-30%,Ni, MH 30-35%. Fast charging and discharging 1C charge for 30 minutes capacity up to 80% per cent of the nominal capacity, now iron phosphate batteries can be charged up to 10 minutes to the nominal capacity of the 90%. High operating temperature range Operating temperature of -25~45 ° c, as the electrolyte and cathode improvements, expected to expand to -40~70 ° c.
