With battery anxiety been a heavy topic of late and how can it be solved going forward this gives some light on what lies ahead,given that manufacturers like to sell extras along with their device such as power bars and wireless chargers this is also a revenue stream for them so how likely they will uptake on this is another days work,but nonetheless its what the consumer wants as today battery life is still a problem especially for power users..
Aluminum has long been an attractive material for batteries, mainly because of its low cost, low flammability and high-charge storage capacity. For decades, researchers have tried unsuccessfully to develop a commercially viable aluminum-ion battery. A key challenge has been finding materials capable of producing sufficient voltage after repeated cycles of charging and discharging.
“We have developed a rechargeable aluminum-ion battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford. “Our new battery won’t catch fire, even if you drill through it.”
“In our study, we have videos showing that you can drill through the aluminum battery pouch, and it will continue working for a while longer without catching fire,” Dai said. “But lithium batteries can go off in an unpredictable manner – in the air, the car or in your pocket. Besides safety, we have achieved major breakthroughs in aluminum-battery performance.”
“Our battery produces about half the voltage of a typical lithium battery,” he said. “But improving the cathode material could eventually increase the voltage and energy density. Otherwise, our battery has everything else you’d dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life. I see this as a new battery in its early days. It’s quite exciting.”
