Different competition between lithium iron phosphate battery and lithium ion battery

1. Lithium iron phosphate batteries are used as lithium-ion secondary batteries. At the moment, the important preference is power lithium batteries, which have great advantages over NI-H and Ni-Cd batteries. Lithium-ion batteries are a type of batteries that use lithium metal or lithium alloy as the positive electrode material and use a non-aqueous electrolyte solution. The chemical properties of lithium metal are very vivid, making the processing, survival and use of lithium metal very demanding. 2. Lithium iron phosphate battery will not fire or explode after puncture, but the lithium ion battery will. 3. Lithium iron phosphate battery will not catch fire or explode if it is overcharged to 100%; lithium ion battery will gas out and swell when it reaches the specified life value. 4. The typical voltage of lithium iron phosphate battery is 3.2V, and that of lithium ion battery is 3.7V. 5. Lithium iron phosphate battery is resistant to overcharge and overdischarge, and it can recover more than 80% when it reaches zero for a short time. Lithium-ion batteries will show irreversible damage when they are over-discharged to 2.6V. 6. Lithium iron phosphate battery can discharge electricity with high power, 10C20C or above is ok, lithium ion battery can only discharge at 3~5C. However, the energy density of lithium iron phosphate batteries is not as great as that of lithium ion batteries. The voltage is also relatively low. Due to its large discharge characteristics, it is important to use power sources, such as electric vehicles and model airplanes. The large capacity of lithium-ion batteries is important for civilian consumption. Lithium iron phosphate batteries recycle lithium iron phosphate (LiFePO4) as the positive electrode material, and use iron as the battery raw material, which is low in cost and high in safety. The P-O bond in the lithium iron phosphate crystal is very stable and difficult to resolve. Even at high temperature or overcharge, it will not cause layout collapse, fever, or formation of strong oxidizing substances, and it has excellent security.
