Ternary Lithium Batteries: Pros, Cons, and Tips for Longer Life

Compared to conventional batteries, lithium batteries have a long life, energy savings, environmental protection, no pollution, low maintenance costs, complete charging and discharging, and are lightweight. There is always a saying that lithium batteries have a long life, so how many times are three lithium battery life cycles? How long does the ternary lithium battery last?

How do ternary lithium batteries work?

Lithium ternary batteries use Ni, Co, and Mn transition metal oxides as cathode materials. With lithium manganese, it integrates the excellent cycling performance of lithium cobalt, the high specific capacity of lithium nickelate, and the high safety of lithium nickelate. Synthesis of lithium embedded oxides of nickel, cobalt, and manganese was achieved by molecular level mixing, doping, coating, and surface modification. It is one of the most widely studied and used lithium-ion rechargeable batteries.

A ternary lithium battery’s cycle life

After a period of use, the lithium battery’s capacity will decrease to 70% of its nominal capacity (at 25°C, normal atmospheric pressure, and 0.2C discharge capacity), which can be considered the end of its life. Typically, the cycle life of lithium batteries is calculated by their full discharge cycle times. The lithium battery will undergo irreversible electrochemical reactions during use that will reduce its capacity, such as decomposition of electrolyte, inactivation of active materials, collapse of positive and negative electrodes, reducing the number of lithium ions embedded and unembedded. When the discharge current is low, the battery voltage will be close to equilibrium voltage, allowing the battery to release more power. Higher discharge rates lead to faster capacity decay.

The theoretical life of ternary lithium batteries is about 800 cycles, which is comparable to that of commercial rechargeable lithium batteries. It is believed that lithium titanate can withstand 10,000 cycles compared to lithium iron phosphate’s 2,000 cycles. Currently, mainstream battery manufacturers are committed to manufacturing three core specifications over 500 times (under standard charge and discharge conditions), but the core in the battery pack, due to consistency problems, mainly voltage and internal resistance, cannot be exactly the same, thus its cycle life is approximately 400 times.

It is recommended that the SOC use window be 10%~90%. Battery electrode structure will be irreversibly damaged if deep charge and discharge is carried out. Using shallow charge and shallow discharge, at least 1000 cycles can be calculated. Further, lithium-ion batteries’ battery life decreases to less than 200 times if they are frequently charged at high power levels and temperatures.


  1. How long does it take to charge a ternary lithium battery?
    A: The charging time of a ternary lithium battery depends on several factors such as the charging current, depth of discharge, and state of charge. It typically takes a few hours to fully charge a ternary lithium battery.

  2. How many cycles can a ternary lithium battery undergo?
    A: Ternary lithium batteries can undergo hundreds of charge and discharge cycles before their performance starts to degrade. They typically have a longer cycle life than other types of lithium-ion batteries.

  3. What is the recommended charging temperature for ternary lithium batteries?
    A: Ternary lithium batteries should be charged at temperatures between 10°C and 30°C to ensure optimal performance and longevity. Charging at higher temperatures can cause thermal runaway and reduce the battery’s cycle life.

  4. Can charging a ternary lithium battery too quickly damage it?
    A: Yes, charging a ternary lithium battery at a higher current than recommended can lead to overheating and damage to the battery. It’s important to follow the recommended charging current specified by the battery manufacturer.

  5. What is the recommended depth of discharge for ternary lithium batteries?
    A: The depth of discharge for ternary lithium batteries should be kept below 80% to ensure optimal battery performance and cycle life. Discharging the battery too deeply can reduce its lifespan and increase the charging time.
