Good news for those addicted to iPhones: Japanese multinational electronics corporation and Apple supplier, TDK, has claimed a solid-state battery breakthrough – 100 hours on a single charge 

The smartphone battery leader claims the new material will boost energy storage for smaller gadgets including wireless headphones and smartwatches.

It’s hoped that the same tech can also be applied to Tesla cars further down the line

How does it charge the battery of small tech and iPhones?

The newly discovered solid-state and all-ceramic batteries contain an oxide-based solid electrolyte and lithium alloy anodes.

They provide an energy density of 1,000 watt-hours per liter.

That’s 100 times greater than the battery offering that TDK has been putting into Apple tech since 2020.

These small solid-state batteries currently offer 50 Wh/l.

Meanwhile, rechargeable coin batteries that use traditional liquid electrolytes can only offer 400 Wh/l.

As well as longer performance and faster charging than liquid electrolytes, solid-state batteries are safer, lighter, and potentially cheaper.

“We believe that our newly developed material for solid-state batteries can make a significant contribution to the energy transformation of society,” TDK’s chief executive, Noboru Saito, explained.

“We will continue the development towards early commercialization.”

While replacing coin-shaped batteries and allowing small gadgets to go further, the oxide also renders the battery more stable and safe.

Prior to the solid-state batties going into mass production, Apple has revealed two basic things everyone can do to make their iPhone battery last longer.

Going a step further, a tech enthusiast revealed their method for ensuring ‘limitless’ iPhone battery life.

But will it work for cars?

Despite offering greater range for EVs, there are obstacles in the way of mass production for larger-sized batteries.

The ceramic material used by TDK means larger batteries would be too fragile for cars or even smartphones

Japanese companies are pushing the technology: Toyota is aiming for 2027, Nissan by 2028, and Honda by 2030.

Sulfide-based electrolytes for long-range electric vehicles have proven a worthy alternative for TDK’s new liquid-electrolyte discovery.

And, if you’re after a powered-up home as well as a car, this new concrete could turn your whole home into a giant battery.
