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

What is Ternary (NCM) lithium battery?

Ternary lithium batteries, or ternary lithium-ion batteries, are a type of rechargeable battery that utilizes a cathode material made from a combination of three different transition metal elements. The term “ternary” refers to the presence of three components in the cathode.

The cathode is the positive electrode in a lithium-ion battery, and it is crucial for the overall performance of the battery. The three metals typically used in ternary cathodes are nickel (Ni), manganese (Mn), and cobalt (Co). These metals are combined in varying ratios to form a ternary compound.

What is Ternary (NCM) lithium battery?

Ternary lithium batteries are known for their improved energy density, which results in higher capacity and longer-lasting battery performance compared to some other cathode materials. These batteries find applications in various devices, including electric vehicles, portable electronics, and energy storage systems, where high energy density and reliable performance are essential.

How do Ternary (NCM) 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.

Ternary (NCM) lithium battery’s cycle life

Lithium batteries have a lifespan, typically considered to end when their capacity decreases to 70% of the nominal capacity. Here are key factors influencing their life:

Ternary (NCM) lithium battery's cycle life

  1. Cycle Life:

    • Calculated by full discharge cycle times.
    • Irreversible electrochemical reactions occur during use, affecting capacity.
    • Theoretical life varies, with lithium titanate enduring 10,000 cycles compared to lithium iron phosphate’s 2,000 cycles.
  2. Mainstream Specifications:

    • Battery manufacturers aim for over 500 cycles (under standard conditions).
    • Inconsistencies in battery pack cores, like voltage and internal resistance, impact cycle life (approximately 400 times).
  3. State of Charge (SOC):

    • Recommended SOC use window is 10% to 90%.
    • Deep charge and discharge can irreversibly damage the battery electrode structure.
    • Shallow charge and discharge enable at least 1000 cycles.

Understanding these factors helps optimize lithium battery life, ensuring longevity and efficient performance.

Is Ternary lithium battery safe?

Ternary lithium batteries, like those used in Tesla cars, are generally safe with the inclusion of a protection plate. This plate helps control factors like overcharging and overheating. However, it’s essential to understand specific safety considerations associated with ternary lithium batteries.

Is Ternary lithium battery safe?

  1. Material Composition and Safety Features:

    • Ternary lithium batteries use nickel, cobalt, and manganese in their cathode, and safety is enhanced by a protection plate.
    • They require careful handling, as they can be vulnerable to overheating or fires, especially when damaged or abused.
  2. Comparison with LiFePO4 Batteries:

    • In contrast to lithium iron phosphate (LiFePO4) batteries, ternary lithium batteries have a lower thermal runaway temperature, making them more prone to catching fire at high temperatures.
    • LiFePO4 batteries are recognized for superior safety, better high-temperature performance, and a longer cycle life.
  3. Charging Guidelines:

    • Charging a ternary lithium battery necessitates following specific guidelines, including using a charger designed for lithium-ion batteries and adhering to the manufacturer’s specifications.
    • Monitoring the charging process, setting appropriate parameters, and avoiding overcharging are crucial steps for safe charging.

In summary, while ternary lithium batteries are generally safe when handled correctly, it’s crucial to be aware of their characteristics, especially in comparison to alternatives like LiFePO4 batteries. Adhering to charging guidelines and safety precautions ensures the responsible use of these batteries.
