By most accounts, it looks as though it will be 2025 or so. Then we’ll start seeing mass production of the next big thing: “solid-state” batteries, or ones that use materials like ceramics, instead of liquid, for the electrolyte.

Solid-state batteries, which will charge up to six times faster and have no flammable liquid, will have twice the energy density and a life span of up to 10 years.

That’s the mainstream breakthrough on the horizon. But plenty of companies are researching batteries that are thin, stretchable and bendable for applications like wearable devices, skin patches and smart packaging.

That’s it for this briefing. See you next time. — Melina
