Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material currently used in most lithium-ion batteries.
Working principle: The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery, called lithium iron phosphate battery. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery. Some people also call it a “lithium iron (LiFe) battery”.
The requirements forrechargeable battery are: high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, capable of charging and discharging large current, electrochemical stability and safety in use (not due to overcharge, overdischarge and short circuit may cause combustion or explosion due to improper operation), wide operating temperature range, non-toxic or less toxic and no pollution to the environment. Lithium iron phosphate batteries using LiFePO4 as positive electrode meet these performance requirements, especially in terms of high discharge rate (5-10°C discharge), stable discharge voltage, safety (no combustion, no explosion) and lifespan (number of cycles), no pollution for the environment, it is the best, and it is currently the best battery in phigh current output power.
