The chemical element commonly used in batteries is lithium, particularly in lithium-ion batteries. Lithium is known for its high energy density, lightweight properties, and ability to undergo many charge cycles without significant degradation. These features make lithium-ion batteries the preferred choice for powering many devices, from smartphones and laptops to electric vehicles. As the world shifts toward sustainable energy solutions, lithium's role in battery technology has gained even more significance, driving interest in lithium mining and recycling technologies.
