In nature, lithium is the lightest and least atomic weight metal, with an atomic weight of 6.94g/mol= 0.53g/cm3. Lithium has active chemical properties and is prone to losing electrons and being oxidized to Li+. Therefore, the standard electrode potential is negative, at -3.045V, with the smallest electrochemical equivalent of 0.26g/Ah. These characteristics of lithium element determine that it is a material with high specific energy. Ternary lithium-ion batteries refer to lithium secondary batteries that use nickel cobalt manganese transition metal oxides as cathode materials. It fully integrates the good cycling performance of lithium cobalt oxide, the high specific capacity of lithium nickel oxide, and the high safety and low cost of lithium manganese oxide. It uses molecular level mixing, doping, coating, and surface modification methods to synthesize composite lithium oxide with multi-element synergy, such as nickel cobalt manganese. It is currently a widely researched and applied lithium-ion rechargeable battery.

What is the lifespan of ternary lithium-ion batteries

Regarding battery life, the typical lifespan of lithium-ion batteries is approximately 5 to 20 years, with an average of 8 years. However, at the current level of technology, the service life of lithium-ion batteries in electric vehicles is only about 3-5 years. The cycle times of ternary lithium-ion batteries are around 500 to 1000 times, the theoretical lifespan of ternary lithium-ion batteries is about 800 times, and the lifespan of iron phosphate lithium-ion batteries is about 2000 times. According to the current technological level of ternary lithium-ion batteries, if used properly, they can be used in electric vehicles for at least 5 years.

The service life of ternary lithium-ion batteries is 2000 charging and discharging cycles, which can also be maintained for more than 5 years. If 1000 charging and discharging cycles are conducted, the ternary lithium-ion battery has essentially decayed by 50%, which means that it can only run half of the original mileage when fully charged. In addition, an excellent battery management system can also slow down the decay of ternary lithium-ion batteries.

If the lithium forklift battery is not charged for a long time, it will reduce its lifespan. Ternary lithium-ion batteries need to maintain a flowing state of electrons for a long time in order to achieve their ideal service life. The commercial production technology of ternary lithium-ion batteries worldwide is not very mature, and their current market share is not high. The theoretical lifespan of ternary lithium-ion batteries is about 800 cycles, which is considered moderate in commercial rechargeable lithium-ion batteries.
