The history of lithium-ion batteries dates back to the 1970s. In 1970, scientists John Gould and Arkady Arkady proposed the concept of lithium metal as a battery anode. However, due to the safety of lithium metal, research progress has been slow. In the 1980s, researchers discovered that the use of graphite as an anode material could effectively improve safety and performance.
In 1991, Japan's Panasonic company and SONY jointly launched the first commercial lithium-ion battery, which marked the official advent of lithium-ion batteries. The advantages of lithium-ion batteries are their high energy density, long cycle life and low self-discharge rate, which have been widely used in consumer electronics products, such as mobile phones and notebook computers.
Entering the 21st century, with the growing demand for electric vehicles and renewable energy storage, the market for lithium-ion batteries continues to expand. Continuous innovation in technology, such as solid-state batteries and fast-charging technology, has further promoted the development of lithium-ion batteries. Today, lithium-ion batteries have become one of the important technologies for modern energy storage and transmission.
