Li-ion stands for Lithium-ion, an energy abbreviation also used in technology.
Rechargeable battery in which lithium ions shuttle between a graphite anode and a metal-oxide or phosphate cathode. Li-ion cells power phones, laptops, power tools, electric vehicles and grid storage because they store more energy per kilogram than older chemistries.
Example: Do not pack spare Li-ion batteries in checked luggage; carry them in the cabin.
Usage notes
M. Stanley Whittingham created the first lithium battery concept in the 1970s, John Goodenough developed a higher-voltage cobalt oxide cathode in 1980, and Akira Yoshino made the first practical design in 1985; they shared the 2019 Nobel Prize in Chemistry, Goodenough at 97. Sony commercialized the battery in 1991. Damaged cells can overheat in thermal runaway, and pack prices fell about 90% between 2010 and the mid-2020s.
