The Battery Is Ready to Power the World
After a decade of rapidly falling costs, the rechargeable lithium-ion battery is poised to disrupt industries
Rechargeable lithium-ion batteries were first commercially used in hand-held camcorders in 1991. Laptops soon followed. A decade later, batteries enabled the rise of tech titans such as Apple Inc. by powering smartphones and wearable devices, then made their way into electric vehicles. The basic technology throughout remained pretty much the same: Lithium ions move through a liquid from the cathode to the anode, and back again.
This, however, was just the beginning. After a decade of rapidly falling costs, the battery has reached a tipping point. No longer just for consumer products, it is poised to transform the way the world uses power.
