LG HE4 18650

High Discharge IMR Chemistry

The LG HE4 IMR 18650 features an IMR Li-ion chemistry, also known as Lithium-ion Manganese Oxide (LiMn₂O₄), which is popular for use in applications that require high-discharge currents. IMR batteries utilize a cathode made from Lithium Manganese Oxide, in a three-dimensional spinel structure that allows for improved ion flow. This results in lower internal cell resistance, which allows for expedited charging and for high-current discharging. While rechargeable IMR batteries offer a lower capacity than other Li-ion types, these cells are utilized specifically for use in high-drain devices and applications, such as within the power tool and medical device industries. Battery packs made with IMR cells have been widely adopted for flashlight, vape, and e-cig applications.
