A New 0.4-MM-Thick ‘Paper Battery’ Can Power a Small Fan for 45 Minutes
Biodegradable paper-thin batteries by NTU Singapore scientists
Powering up with paper batts: #NTUsg scientists have developed paper-thin #biodegradable zinc #batteries that could one day become a more #ecofriendly option for powering smart devices and #wearableelectronics such as foldable smart phones. Once expended, the #ecofriendly batteries break down in soil within weeks.
Scientists from Nanyang Technology University (NTU) in Singapore developed paper-thin biodegradable zinc batteries, a press statement reveals. They believe the new material could sustainably power flexible wearable electronics of the future.
The new zinc batteries are made up of electrodes that are screen-printed onto both sides of a sheet of hydrogel-reinforced cellulose paper. A layer of gold thin foil is coated on the electrodes to increase the conductivity of the battery. The battery is about 0.4mm thick, which is roughly the thickness of two strands of human hair.
