The 21700 battery is a lithium-ion cell that measures 21mm in diameter and 70mm in height. Larger than its predecessors, like the 18650 battery, the 21700 has gained popularity due to its higher energy density and improved longevity. It’s designed to meet the growing demands for energy storage, specifically in high-drain applications such as electric cars and portable power banks.
Various technologies play a crucial role in 21700 battery production. Each technological approach has its unique advantages:
NMC technology combines nickel, manganese, and cobalt in varying ratios to enhance performance. Known for its balanced power and capacity, NMC provides efficient power delivery and is frequently employed in electric vehicles. As manufacturers optimize NMC formulations, battery life and weight can be improved without sacrificing safety.
LFP technology is renowned for its stability and safety features. While it may not offer the same energy density as NMC, its thermal stability reduces the risk of thermal runaway, making it a preferred choice for stationary energy storage systems. LFP batteries tend to have a longer cycle life, making them an ideal option for applications requiring longevity.
Lithium titanate batteries are distinct in their ability to charge rapidly and operate efficiently at high temperatures. Although they come with lower energy density, their extended cycle life and fast-charging capabilities make them suitable for applications where quick energy replenishment is essential.
Several brands dominate the 21700 battery manufacturing landscape, each with its unique selling points. Here are some notable names:
