When Sony introduced the first lithium-ion batteries in 1991, they knew of the potential safety risks. A recall of the previously released rechargeable metallic lithium batteries was a bleak reminder of the discipline one must exercise when dealing with this high energy-dense batteries system.
Pioneering work for the lithium batteries began in 1912 by G. N. Lewis. It was not until the early 1970's when the first non-rechargeable lithium batteries became commercially available.
Attempts to develop rechargeable lithium batteries followed in the eighties. These early models were based on metallic lithium and offered very high energy density. However, inherent instabilities of lithium metal, especially during charging, put a damper on the development.
The cell had the potential of a thermal run-away. The temperature would quickly rise to the melting point of the metallic lithium and cause a violent reaction. A large quantity of rechargeable lithium batteries sent to Japan had to be recalled in 1991 after the pack in a cellular phone released hot gases and inflicted burns to a man's face.
Because of the inherent instability of lithium metal, research shifted to a non-metallic lithium batteries using lithium ions. Although slightly lower in energy density, the lithium-ion system is safe, providing certain precautions are met when charging and discharging. Today, lithium-ion is one of the most successful and safe batteries chemistries available. Two billion cells are produced every year.
