One of the main drawbacks of NCM batteries is their higher cost compared to other battery types, such as lead-acid or even some lithium iron phosphate (LiFePO4) batteries. The use of cobalt, in particular, contributes to this expense due to its limited availability and fluctuating market prices.
2. Safety Concerns
While NCM batteries are generally safe, they can pose safety risks if not managed properly:
-
Thermal Runaway: Like all lithium-ion batteries, NCM cells can experience thermal runaway if subjected to extreme conditions or damage.
-
Cobalt Content: The presence of cobalt raises concerns about ethical sourcing and environmental impact.
3. Limited Availability
As demand for NCM batteries grows, sourcing the necessary materials can become challenging. This limited availability may affect production timelines and costs.
Tips for Maximizing the Lifespan of NCM Batteries
To ensure that your ternary lithium batteries last as long as possible, consider the following tips:
1. Optimal Charging Practices
-
Avoid Overcharging: Always use a charger designed specifically for NCM batteries to prevent overcharging, which can lead to reduced lifespan.

Charge at Moderate Temperatures: Charging at extreme temperatures can harm battery health. Aim to charge your NCM battery within the recommended temperature range.
2. Maintain Proper Storage Conditions
-
Cool and Dry Environment: Store your NCM batteries in a cool, dry place away from direct sunlight and moisture.
-
Partial State of Charge (SoC): If storing for an extended period, maintain the battery at a partial state of charge rather than fully charged or fully discharged.
3. Regular Maintenance Checks
Conduct regular inspections to identify any signs of wear or damage. Monitor voltage levels and overall battery health to address any issues promptly.
