Battery technology has come a long way since the first battery was created by Alessandro Volta in 1800. Early batteries, like the lead-acid battery, were bulky and inefficient, offering limited energy storage. Over the years, advancements such as the nickel-cadmium and nickel-metal hydride (NiMH) batteries brought improvements in capacity and rechargeability. However, it was not until the development of lithium-ion (Li-ion) batteries in the 1990s that significant breakthroughs in energy density, lightweight design, and longevity were achieved. These lithium-based batteries became the standard for many portable devices and electric vehicles due to their superior performance and energy efficiency.
