New Flexible Lithium-ion Battery developed by Panasonic


With all the negative exploding and bulging battery articles these days, it’s time for some pretty cool news on the lithium-ion battery front. It turns out that Panasonic has been working on a thin, twistable, bendable, Flexible Lithium-ion battery for use in card devices, devices attached to the human body, smart clothing, wristband wearable devices, and more.

Panasonic’s Flexible Lithium-ion Battery has the following features:

  • The battery can maintain its characteristic even with repeated bending and twisting.
  • The battery contributes to longer life of devices as it retains charging and discharging characteristics even with repeated bending and twisting.
  • The battery can be used reliably for devices attached to the human body because of excellent safety.

The batteries have a thickness of just 0.55mm (0.022 inches), and can retain their characteristics even after repeatedly getting bent into a radius of 25mm or twisted to an angle of 25 degrees. In addition, Panasonic’s testing has shown that the batteries have an 80% initial capacity retention based on a test that consists of a charge and discharge cycle followed by either bending or twisting a total of 1,000 times. The company is using a newly-developed laminated outer body and internal structure that keeps the batteries from leaking or overheating during repeated twisting and bending.

Given the size, they are fairly low capacity as well, with capacities of 17.5mAh, 40mAh, and 60mAh depending on the size. The smallest has dimensions of only 28.5mm x 39.0mm and weight just 0.7 grams, while the largest has dimensions of 40.0mm x 65.0mm and weighs just 1.9 grams.

The batteries will be on display at CEATEC JAPAN 2016 from October 4 to 7 at Makuhari Messe, with samples for product development being shipped out at the end of October.
