A Lithium-Ion Battery That You Can Scrunch

Researchers Transmit Energy With A Laser In 'Historic' Power-Beaming Demonstration



An nameless reader quotes a report from IEEE Spectrum: Busan-based agency Jenax has spent the previous few years creating J.Flex, a sophisticated lithium-ion battery that’s ultra-thin, versatile, and rechargeable. With the arrival of so many wearable devices, telephones with versatile shows, and different transportable gizmos, “we’re now interacting with machines on a distinct degree from what we did earlier than,” says EJ Shin, head of strategic planning at Jenax. “What we’re doing at Jenax is placing batteries into areas the place they could not be earlier than,” says Shin. Her agency demonstrated a few of these new prospects final week at CES 2020 in Las Vegas.

The gadgets proven by Jenax included a sensor-lined soccer helmet developed by UK-based agency HP1 Applied sciences to measure stress and pressure of affect; a medical sensor patch designed in France that will likely be embedded in clothes to watch a wearer’s coronary heart fee; and wearable energy banks within the type of belts and bracelets for sufferers who should repeatedly be hooked as much as medical gadgets. To make batteries versatile, firms mess around with the elements of a battery cell, particularly the cathode, anode, electrolyte, and membrane separator. Within the case of Jenax, which has greater than 100 patents defending its battery know-how, Shin says the key to its flexibility lies in “a mix of supplies, polymer electrolyte, and the know-how developed over time.” J.Flex is constructed from graphite and lithium cobalt oxide, however its actual composition and structure stays a secret. “J.Flex might be as skinny as 0.5 millimeters (appropriate for sensors), and as tiny as 20 by 20 millimeters (mm) or as massive as 200 by 200 mm,” the report provides. “Its working voltage is between three and 4.25 volts. Relying on the scale, battery capability varies from 10 milliampere-hours to five ampere-hours, with near 90 % of this capability remaining after 1,000 charge-discharge cycles. Every cost usually takes an hour. J. Flex’s battery life is dependent upon the way it’s used, Shin says — a single cost can final for a month in a sensor, however would not final that lengthy if the battery was powering a show.”
