Lithium batteries can be generally divided into two varieties: Lithium metal battery and lithium ion battery. Lithium ion battery does not contain lithium in metal state, and can be charged, but due to its own high technical skills, only a few countries’ companies have the ability to produce, Lithium metal battery is most widely used at the market.
How lithium iron phosphate battery works:
Lithium iron phosphate battery (LiFePO4) generally refers to lithium ion batteries that use lithium iron phosphate as the cathode material. The negative terminal consists of graphite, the separator is in the middle which commonly uses PP/PE/PP (PE: polyethylene; PP: polypropylene). The electrolyte can add a variety of substances, such as the using of tri-n-butyl phosphate (TBP).
During the process of charging lithium iron phosphate battery (LiFePO4) power battery, Li ions constantly come out from the positive terminal, and then move to negative terminal; when the capacity is about to be saturated, the Li ions are almost embedded in the cathode entirely, forming the overcharge protection voltage, therefore the safety of performance and stable working ability is beyond doubt.
Mainly advantages:
Outstanding high-temperature performance and stability:
Lithium iron phosphate battery has excellent safety with a safe and reliable structure and does not burn or explode.
With excellent cycle life and using experience:
Its discharge capacity can still surprisingly reach up to 80% after 3500 times cycles; low cost; traditional nickel batteries have memory effect (Long-term charging and discharging can easily reduce the capacity of the battery), nevertheless the lithium iron phosphate battery requires no discharge before its charging.
With excellent portability:
Using lithium iron phosphate battery on the vehicles can greatly reduce the weight, improve the cruising capability and mileage. From the above inductive characteristics we can very easily find its performance is extremely suitable for power applications, it is widely used in electric vehicle industry, such as the recently hot BYD electric car and very common electric vehicle, even in some surveys in dangerous sites and emergency equipment. The core power source of a lithium iron phosphate material can provide stable and efficient output while ensuring unparalleled security.
