The battery of the future will be measured in millimeters and recharged in seconds. Researchers at the University of Illinois at Urbana-Champaign have designed a new lithium-ion battery that’s 2,000 times more powerful than current storage technology and can be recharged 1,000 times quicker:
The batteries owe their high performance to their internal three-dimensional microstructure. Batteries have two key components: the anode (minus side) and cathode (plus side)…[Researchers] developed a new way to integrate the two components at the microscale to make a complete battery with superior performance.
With so much power, the batteries could enable sensors or radio signals that broadcast 30 times farther, or devices 30 times smaller…imagine juicing up a credit-card-thin phone in less than a second. In addition to consumer electronics, medical devices, lasers, sensors and other applications could see leaps forward in technology with such power sources available.
“Any kind of electronic device is limited by the size of the battery – until now,” [lead researcher William P.] King said. “Consider personal medical devices and implants, where the battery is an enormous brick, and it’s connected to itty-bitty electronics and tiny wires. Now the battery is also tiny.”
It won’t be revolutionary until it’s proven capable of commercial production. Nonetheless this is an extraordinary breakthrough that has countless important applications. Imagine jump-starting your car with your cell phone, and then recharging your phone battery in a matter of seconds. We can’t wait to own our own superbattery-powered devices.
