History of Batteries

From NiCd to Enevate:
A History of Innovation

Advancements in rechargeable batteries have paralleled innovations in mobile devices, but major capacity advancements have also required changes in manufacturing, power management ICs, charging electronics, and device platforms.

Today, Enevate takes innovation a step further with its HD-Energy® Technology—and it requires no major changes in the manufacturing ecosystem.

  • 1960-70s – Rechargeable NiCd batteries fueled the rise of cordless phones, but were heavy and produced a “memory effect” which ultimately affected performance.
  • 1980s – NiMH batteries had higher capacity and no “memory effect,” but required all new charging and management circuits.
  • 1990s – Dr. John Goodenough substantially increased energy density with Lithium-ion (Li-ion) batteries by tripling voltage, making batteries 40% smaller and lighter, and allowing re-charging in any condition. It also required all new charging and power management electronics, as well as new battery manufacturing processes and factories.
  • 2015 – Enevate’s advanced HD-Energy Technology Li-ion batteries deliver a full charge in 15 minutes and can extend battery runtime by up to 50% longer. Plus, their thin form factor makes them ideal for embedding in next-generation ultrathin electronic devices.
