Bendy smartphone dream moves closer thanks to Panasonic’s new batteries

Panasonic has revealed a new fully flexible lithium-ion battery unit that could one day pave the way for bendable smartphones and wearable devices.

The company plans to show off a battery that can be bent and twisted a thousand times while still retaining 99 per of its charge.

That’s possible due by a new means of proprietary lamination that’ll prevent the fluid from leaking, meaning it can be worn close to the skin.

In its current guise, the batteries offer between 17mAh and 60mAh of power, so it’s nowhere near ready for the modern mobile device. However, it seems perfect for smart clothing.

“The battery can be used reliably for devices attached to the human body because of excellent safety,” Panasonic says (via SlashGear).

Many items of fitness clothing currently feature smart low-powered sensors, so this development could up the game somewhat.

The largest 60mAh battery is just 40mm x 25mmm in size so it could comfortably be added to the inner lining of a shirt without being too obvious.

Panasonic says suitable applications include “card devices, devices attached to the human body, smart clothing, wristband wearable devices, etc.”

The firm reckons samples will be heading out next month, but it may be a good while before we start seeing them in consumer devices.
