Panasonic unveils bendable, flexible lithium-ion batteries

Panasonic one of the leading battery providers in the smartphone business has just announced it has developed a flexible lithium-ion battery. The battery can be used in wearable devices or any card-type electronics, as it's only 0.55mm (0.022 inches) thin.

According to Panasonic, the rechargeable battery can withstand bending and twisting beyond the Japanese Standards for identification cards (bending radius R40mm, twisting angle ± 15 degrees/85.6mm. On top of that, the battery is capable of maintaining its characteristics even after being repeatedly bend and twisted. The same goes for the charging and recharging characteristics.

And if you're thinking of safety, Panasonic confirmed that its new flexible battery is safe to use in devices attached to the human body, including smart clothing and wristband wearable devices.

The first shipments of Panasonic's bendable batteries are scheduled to start by the end of October 2016. While the product development will continue with the final purpose of mass production, Panasonic is determined to make its flexible battery even slimmer in order to be included in various IoT devices such as card and wearable devices.

The disappointment comes in the fact that the nominal capacity for Panasonic's flexible lithium-ion battery is as high as 60mAh, which means they're not meant to be included in smartphones. Two smaller models will be shipped next month as well, with a nominal capacity of 17.5mAh and 40mAh.

Hopefully, the new technology can be applied to larger capacity batteries, otherwise we won't see any true flexible smartphones on the market anytime soon.

"makes it difficult" Que: 'look I can bend the battery!' *keeps doing something until it breaks and like anything lithium battery based, goes up in a fireball*

Units? There is only one chinese man who claims his replacement unit exploded. There are several iphones who have exploded aswell, does that mean all are affected?

The ReserveStrap already exists but it would be easier and less bulky

I'm glad batteries are getting safer. I really want a longer lasting battery! The day my s7 or a device of the latest generation can last as long as my Motorola Startac then I will be happy

I'm just waiting for Samsung to get in on this technology and enter the apparel business. I can't say as much about the world as a whole, but such explosive clothing would be wildly popular among Middle Eastern radicals.
