Engadget has an interesting look at a flexible battery in the form of a watch strap that was being shown at this years Computex. Able to be seamlessly incorporated into a watch, the battery offers between 300mAh and 500mAh of additional power. This extra power could make a meaningful difference in a wearable device where battery longevity is critical. To put things in perspective the battery on a Pebble is 130mAh and the battery of a Samsung Gear 2 is 300mAh. The 300mAh battery strap would conceivably allow a Pebble to go 16 to 23 days without a recharge. Safety has also been addressed,
the battery makes use of solid state lithium-ceramic cells. These cells are not volatile and can be cut or punctured without fear of injury or explosion. In fact, Engadget claims to have seen a demo of a sliced strip of the band still able to power LED lights. No word when we will start seeing these in wearable devices but the company is already manufacturing the 1.5mm thick batteries..
