A research to produce efficient aluminum batteries carried out by students at Stanford claims to produce batteries that can be charged in a minute and can power a smartphone.
The battery is not the first of its kind to use aluminum ions to power the battery. Earlier we have lithium, lithium polymer and nickel-cadmium batteries. The battery has seen to have far better life then previous aluminum batteries.
Stanford’s new battery can be recharged around 7,500 times. Typical lithium-ion batteries used in everything from smartphones and laptops to electric cars last around 1,000 recharge cycles.
The new aluminium-ion batteries are far from being available for commercial use in electronics, as they produce just half the voltage of lithium-ion batteries.
“I see this as a new battery in its early days. It’s quite exciting,” said Ming Gong, one of the authors of the study published in Nature. “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.”
The new aluminium battery technology is not the only one vying to solve our battery life crunch – the primary issue holding back current electronic devices.
