The development of the first commercial lithium-ion battery was a collaborative effort involving Stanley Whittingham, John Goodenough, and Akira Yoshino. It was first commercialized by Sony in 1991. These batteries are rechargeable and have a much higher energy density than traditional lead-acid or nickel-cadmium batteries, meaning they can store more power in a smaller, lighter package. This invention was the essential 'missing link' that allowed for the mobile electronics revolution, enabling the creation of smartphones, laptops, and tablets that could last for hours. Today, lithium-ion batteries are the primary technology powering the global transition to electric vehicles (EVs) and the storage of renewable energy from solar and wind. The inventors were awarded the Nobel Prize in Chemistry in 2019 for their work in creating a 'rechargeable world.'
