History of Lithium-Ion Batteries
Rechargeable battery evolution accelerated as the world transitioned to instruments enabled by
silicon microchip technology from those of bulky electrical components. Mobile devices were
designed to be powered by lightweight energy storage systems. The development of batteries for
this rapidly evolving market was challenging:
• The nickel cadmium battery had been the only option for modern electronics for many years. It
was a great improvement over carbon batteries.
• Later, nickel-hydride batteries became the technology of choice.
• Lithium-ion batteries became available in the 1990s, offering higher energy densities. This
technology won out nickel-hydride.
The lithium-ion rechargeable battery offered advantages that were previously unavailable:
• Lithium is the lightest of all metals
• It had the largest electrochemical potential
• It provided the greatest energy content per unit volume
• It had no memory effect
• Its energy leakage rate was less than half that of NiCd and NiMH
