The differences between lithium iron phosphate batteries and lithium batteries are: ① The main direction of lithium iron phosphate battery is power battery. ②Lithium iron phosphate battery uses LiFePO4 and carbon as positive and negative electrode materials; lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive electrode material and uses non-aqueous electrolyte solution. ③The lithium iron phosphate battery will not catch fire and explode, but the lithium battery will. ④Lithium iron phosphate is resistant to overcharge, and will not catch fire and explode to 100%, and the lithium battery will swell when it reaches the specified value.
