Flexible Battery Breakthrough In Quest For A Bendable Phone

South Korean researchers have unveiled a way to create flexible battery.

The breakthrough is the latest step forwards on the quest to create a bendable phone, which everyone seems to want for no specific reason.

The usual method involves pouring liquefied electrolytes into square-shaped cases, according to a report by Korea Joongang Daily.

But according to the South Korean government, Professor Lee Sang-young of the Ulsan National Institute of Science and Technology led a team which has now succeeded in finding another way.

Their method involves using "imprintable, fluid-like polymer electrolytes", whcih can bend and are more stable, reducing the risk of an explosion during manufacture.

The scientists describe the new process "like spreading jam of bread". The electrolytes are spread onto electrodes and exposed to ultraviolet light for 30 seconds.

"Conventional lithium-ion batteries that use liquefied electrolytes had safety problems as the film that separates the electrolytes may melt under heat, in which case the positive and negative elements may come in contact, causing an explosion," said an official, according to the Korean Paper.

The idea of a 'bendy' phone has always captured the imagination, and recent breakthroughs in building flexible displays was an important step forward.

But without a way to power it, the phone wasn't going to set the world alight. This breakthrough could change that - look for it at a Samsung Galaxy S6 announcement in a few years time.
