The difference between lithium iron phosphate battery and ternary lithium battery

Lithium iron phosphate battery Lithium iron phosphate battery refers to a lithium battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium batteries include lithium cobalt acid, lithium manganese acid, lithium nickel acid, three materials, lithium iron phosphate and so on. Lithium cobalt oxide is the negative electrode material for most lithium batteries. Regarding the cathode material of LiFePO4, the source of raw materials is wide, the cycle life is long, the safety index is high, and the environmental pollution is small, and it has a strong comprehensive function in many cathode materials. When the lithium iron phosphate lithium battery is charged, the positive lithium ion lithium moves to the negative electrode through the polymer membrane. During the discharge process, the lithium ions in the negative electrode move to the positive electrode through the separator. Lithium batteries are named after lithium ions move back and forth during charging and discharging. Advantages of lithium iron phosphate batteries 1. Lithium iron phosphate batteries have a long life, with a cycle life of more than 2000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years. 2. Safe to use. Lithium iron phosphate batteries have undergone strict safety tests and will not explode even in traffic accidents. 3. Fast charging. Use a dedicated charger, 1.5c charge for 40 minutes to fully charge the battery. 4. The lithium iron phosphate battery is resistant to high temperature. The hot air value of lithium iron phosphate battery can reach 350~500℃. 5. The lithium iron phosphate battery has a large capacity. 6. The lithium iron phosphate battery has no recall effect. 7. Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, and cheap in raw materials. Ternary lithium battery A ternary lithium battery refers to a lithium battery that uses lithium nickel cobalt manganate as the positive electrode material and graphite as the negative electrode material. Different from lithium iron phosphate, the ternary lithium battery has a high voltage path, which means that for the same volume or component, the ternary lithium battery has a higher specific energy and power. In addition, ternary lithium batteries also have great advantages in terms of charging rate and low temperature resistance. Compared with lithium iron phosphate batteries, ternary lithium batteries are more suitable for current and future household electric vehicles. Ternary lithium batteries have better low-temperature resistance. It is the first low-temperature lithium battery manufacturing technology road. At 20C to below zero, ternary lithium batteries can release 70.14% of the output, and lithium iron phosphate batteries can only release 54.94 of the output. %, because under low temperature conditions, the way the ternary lithium battery discharges is much higher than the way the lithium iron phosphate battery voltage starts faster. Lithium iron phosphate batteries are superior to lithium ternary batteries. The theoretical life of the latter is 2000 cycles, but when it reaches 1000 cycles, its capacity drops to 60%. Even the best brand in the industry, Tesla, after 3000 cycles, the battery capacity is only 70%, while the lithium iron phosphate battery after the same cycle, the capacity is only 80%. The above is the difference between lithium iron phosphate battery and ternary lithium battery. As for which battery to choose, the appropriate lithium battery should be selected according to the actual situation.
