【山东省潍坊市2022-2023学年高三上学期期中试题】Electronics woven (编织) into fabrics promise to open up all kinds of interesting possibilities, from clothing that monitors muscle activity and tracks breathing, to garments that can talk to one another. Developing pliable power sources to go with them is an equally important field of research, so scientists at the University of British Columbia have put forward a particularly impressive solution that they say could be the first ever battery that is both stretchable and washable.
To develop a battery with such capabilities, the scientists reimagined the way these devices are put together. Rather than forming a lithium-ion battery packed with hardened materials inside a rigid exterior, the team turned to an alternative chemistry in zinc-manganese (锌锰) dioxide, which is appealing for its low cost and safety. These materials were ground down into tiny pieces and inset in a polymer (聚合物) to form very thin and stretchable layers.
“We went with zinc-manganese because for devices worn next to the skin, it’s a safer chemistry than lithium-ion batteries, which can produce deadly compounds when they break,” says Nguyen.
The resulting battery is flexible and can be stretched to twice its normal length, has a specific capacity of 160 mAh g-1 and keeps 75 percent of its capacity over 500 charge and discharge cycles. Impressively, the team found the battery to withstand 39 wash cycles so far.
The team is now working to improve the power output and lifetime of the battery, and says the creation has already attracted commercial interest, with the cost expected to be similar to a standard rechargeable battery. They imagine it being put to use in watches and patches that measure vital signs, and in smart clothing that does much the same thing.
