Original DMEGC INR18650-29E 18650 Battery 1000 Cycles 3.7V 2900mAh
Li-ion Battery
Lithium ion Battery Features Overview
Lithium-ion battery, as a relatively mature and widely used battery
technology, its core principle lies in the migration of lithium
ions between the positive and negative electrodes of the battery.
This migration process enables the storage and release of
electrical energy, providing continuous and stable power for many
electronic devices.
Ternary lithium battery, as an improved type of lithium-ion
battery, its biggest feature is the use of lithium nickel cobalt
manganese oxide (LiNiCoMnO2, NMC for short) as the cathode
material. The introduction of this material has significantly
improved the performance of ternary lithium batteries.
