Properties of different lithium iron phosphate battery: lithium iron phosphate lithium ion battery with lithium iron as a positive electrode material. Ternary lithium battery: The cathode material of lithium lithium nickel cobalt manganate or lithium nickel cobalt aluminate is a ternary cathode material. Main materials different lithium iron phosphate battery: lithium ion batteryThe main cathode materials are lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate and so on.
Ternary lithium battery and lithium iron phosphate battery is different in nature, the main material is different, the energy density is different, the application is different and the temperature resistance is different. The lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate as the positive electrode material. The cathode material in the ternary lithium battery is nickel-cobalt lithium manganate or nickel-cobalt lithium aluminate ternary cathode material.
Different properties Lithium iron phosphate battery: lithium iron phosphate is used as a positive electrode material lithium ion battery. Ternary lithium battery: The cathode material uses nickelLithium cobalt manganate or lithium nickel cobalt aluminate ternary cathode material lithium battery. The main materials are different lithium iron phosphate batteries: the positive electrode materials of lithium ion batteries are mainly lithium cobalt, lithium manganese, lithium nickel, ternary materials, lithium iron phosphate, etc.
Different materials. Lithium iron phosphate battery refers to the lithium ion battery using lithium iron phosphate as a positive electrode material, and ternary lithium battery refers to the lithium ion battery using nickel cobalt manganese oxide lithium as a positive electrode material. The energy density is different. The energy density of the lithium iron phosphate battery cell is about 110Wh/kg, and the energy density of the ternary lithium battery cell is about 200Wh/kg. temperature
1, if you want to make the battery life long, we should make the battery power as much as possible at more than 40%. For lithium batteries, if often from a full state to completely used up not only does not help, there will be some small damage. In addition, there is a trick, is to remove the battery before it is full, the battery will last longer, and if the battery is full, but also continue to plug in the charger, which will lead to the degradation of the battery.
2, after the mobile phone is fully charged, it is recommended that you unplug the charger to avoid long-term charging or long-term high power state to accelerate the aging of the battery to extend the batteryService life. (2) If the mobile phone is idle for a long time, it is recommended that the mobile phone is shut down and not regularly charged to maintain about 50% of the electricity. If the mobile phone is not used or charged for a long time, the battery may trigger over-discharge protection, resulting in abnormal charging or no charging.
3, the current smart phone uses lithium batteries, compared with the previous generation of nickel-metal hydride batteries, lithium batteries have a longer life. Under normal circumstances, mobile phone lithium batteries can still maintain more than 80% of the battery capacity after 300-500 cycles of charging. If the phone battery is full, the power is only less than 80% of the design capacity, the battery should also be eliminated. In other words, the life of the mobile phone battery is determined by the number of cycles of charging.
4, the phone battery is charged and discharged times, so it may have a certain impact on the battery life.
