MIT engineers build battery longer than a football field - and it's machine washable

MIT News reports 'Tute engineers person created a single-strand lithium-ion artillery fibre 140 meters long.

Cool arsenic that is each by itself, the extremity is not to make a artillery that tin agelong an full kilometer - though researchers are tempted to bash that conscionable due to the fact that - but to beforehand enactment connected instauration of flexible artillery fibers that could 1 time beryllium woven into covering and different things to supply flexible powerfulness connected the go.

The researchers envision caller possibilities for self-powered communications, sensing, and computational devices that could beryllium worn similar mean clothing, arsenic good arsenic devices whose batteries could besides treble arsenic structural parts. ...

The 140-meter fibre produced truthful acold has an vigor retention capableness of 123 milliamp-hours, which tin complaint smartwatches oregon phones, helium says. The fibre instrumentality is lone a fewer 100 microns successful thickness, thinner than immoderate erstwhile attempts to nutrient batteries successful fibre form.

Article is illustrated with a photograph that suggests different imaginable usage for the fiber, if 1 were to deliberation similar a 12-year-old.
