Panasonic develops flexible batteries for wearables and smart cards

Date: 01/10/2016
Japanese electronics device maker Panasonic has developed a flexible thin Lithium-ion battery of thickness 0.55 mm/0.022 inches. The immediate application suggested for this battery include wearables and card type devices. The newly researched batteries can withstand multiple bends and twists up to 25.

Panasonic uses stacked electrode construction and laminated outer layer to resist bending and twisting, last longer, and produce less heat while charging and discharging.

The new battery has shown 80% initial capacity retention based on the company's unique testing of 1,000 times of charge and discharge cycle following either 1,000 times of bending or 1,000 times of twisting.

Smart cards and card keys can use these batteries so that user no need to worry about failure of the device due to bending inside the wallets and pockets or when they are kept in tight spaces. Other interesting areas of application are body worn devices and smart clothing. Panasonic claims this battery can retain its characteristics even if the device is frequently bent or twisted.

The visitors at the ongoing event named "CEATEC JAPAN 2016" up to October 7 at Makuhari Messe can see this technology where Panasonic is displaying.

These batteries meet JIS Standard for Cards (JISX6305-1) equivalent bending radius R40mm, twisting angle 15/85.6mm

The samples of the flexible batteries are available by end of October 2016.
