It is flexible, elastic and allows for greater air flow. A new step for “smart clothing”.
A new lithium battery bag makes clothes more “breathable” than cotton, through a material that resists physical stress.
“This is especially useful for athletes or individuals who use electronic devices for long periods of time – intelligent clothing To follow the physical form, medical monitoring devices and similar applications that require comfort and reliable performance, ”says Lin Xu, one of the authors published this Friday at Matter.
Researchers created a standard of long and rectangular holes in a Bag Battery – A type of lithium battery that resembles a flat beam with a limited degree of folding capacity
“A challenge was to maintain sufficient active material to maintain the energy density of the high battery – too much holes or holes would reduce the energy storage capacity,” the researcher tells. “We had to balance Mechanical stretching capacity with electrical performance“.
The design of Holey battery It was then able to resist physical stress and continue to feed LED lamps. It was tested with 100 folds, and tests were performed in a moisture temperature chamber that proved that the material is, in fact, more breathable than cotton – The battery dissipates the heat quickly.
Now the next step is the marketingand is also the biggest challenge: it will be necessary to produce mass without bad placement of the holes, which would undermine the battery bag (which could suffer a short circuit or an escape).
Still, and even though it takes more tests before production to the sportswear market, it is an innovation that is a step forward to improve the quality of sportsmen’s clothes – and not only.
