Lithium Ion Battery
A lithium-ion battery (Li-ion) stands as a modern marvel in rechargeable energy storage, revolutionizing portable electronics, electric mobility, and grid-scale energy management. Guiding lithium ion movement through charge and discharge cycles, it harmonizes electrochemistry with precise engineering. Featuring a graphite anode facilitating lithium ion intercalation during charging, coupled with a cathode of lithium metal oxide like LiCoO2 or LiFePO4, this synergy unfolds within a porous separator, optimizing ion transport. Governed by a non-aqueous electrolyte housing a dissolved lithium salt, the Li-ion battery delivers unparalleled energy density, lightweight design, and enduring longevity. Mitigating thermal runaway risk remains crucial, propelling ongoing advancements in thermal management and Li-ion battery technology.
