Samsung showcases bendable, rollable batteries for future wearables
Samsung has showcased its new battery solution for future wearables, a bendable battery that is flexible enough to be rolled up into a hoop. The South Korean tech giant made the introduction at InterBattery 2014 in Seoul, dubbing it the “world’s first truly flexible battery”. It can be laid flat, bent into a U shape and even rolled up, and still operate normally. This could see future product designs become more daring and comfortable for the wearers, reports Digital Trends.
The flexibility in the new batteries is said to stem from changes in structural design and improved materials. With Samsung and its rival OEMs paying increasing attention to curved screen devices ranging from TVs, smartphones to wearables, the innovation is expected to feature heavily in upcoming wearable technology from the company. Even though Samsung claims that the development stage is complete, the technology will still need time to mature and the company has not given a time frame as to when it might be used in actual commercial products other than a lose term of “years”.
Understandably, technologies as such do take time to ensure both safety and reliability can be increased. With the reliability of the cells apparently still low, even if they do work when deformed, it suggests that the performance will not be up to scratch.
“As we secured winding manufacturing technology – a key process to cut production costs – and related patents, we will be able to become a leader in the wearable era,” said spokesman Seo Hae-su according to the Korea Times.
Samsung revealed a 210mAh curved battery back in April, which can now be found in its Gear Fit smartwatch. During the tradeshow, an unusual pill-sized battery was also revealed by the company, measuring 3.6mm across and 20mm long, but holds a capacity of just 10mAh.
