Batteries come in different shapes, sizes, and compositions, each designed to meet specific power requirements and usage scenarios. While traditional alkaline batteries are commonly used in everyday devices like remote controls and flashlights, rechargeable lithium-ion batteries are preferred for high-performance electronics such as smartphones and laptops. The advancements in battery technology have led to the development of more efficient and long-lasting power sources, enabling the transition towards a more sustainable and energy-efficient future.
