🧪 Understanding 18650 Cell Chemistry
There are multiple chemical variants for 18650 lithium-ion cells, each with its own features and price range:
-
IMR18650: Manganese-based (Low cost, ~1200–1800mAh)
-
ICR18650: Cobalt-based (Higher energy density)
-
INR18650: Nickel-based (Balanced performance and safety)
-
NCR18650: Combination of Nickel, Cobalt, Manganese (NCM) in optimized ratios such as NCM 532 / NCM 523 / NCM 811, offering high energy density and cost-efficiency
In this project, we selected NCR18650 cells, which are widely recognized as a premium choice for commercial electronics due to their excellent stability, reliability, and safety.
