Elon Musk is a leading innovator, likened to Tony Stark, with projects like SpaceX and Hyperloop. His latest venture, the Gigafactory, aims to revolutionize energy storage by mass-producing lithium-ion batteries, reducing costs for electric cars and renewable energy storage. Lithium-ion batteries are popular due to their rechargeability, but they pose safety risks due to combustible electrolytes. Musk is exploring safer alternatives and has patented a lithium-air battery for enhanced performance.
