Lithium-ion Batteries: High Energy Density & Long Cycle Life Solutions

The movement of lithium ions between electrodes occurs during charging and discharging in lithium-ion batteries. They utilize commercially available energy sources such as cars and offer a good balance between power and price. Li-ion (Lithium Ion) batteries have various advantages like relatively high energy density, long cycle life, and low self-discharge rate in comparison to other types of batteries. A Lithium-metal battery (LiMb) substitutes the anode with a metal lithium, thus possessing greater energy potential by default. LiMb batteries, however, pose serious security issues, such as dendrite branches which short circuit readily during charge/discharge cycles; unlike Li-ion batteries that are preferable for primary commercial applications. Metal lithium batteries are still being developed for more practical usage.
