From Maximum PC: It seems that we're always learning about promising new battery technologies, most of which make big claims but are years from becoming a mainstream product, if it even gets that far. So, we're a little jaded. We're also admittedly excited about a new aluminum-ion battery prototype developed by researchers at Stanford. Among the battery's many benefits, it's capable of fully recharging a smartphone in only a minute.
This isn't the first time a laboratory has created an aluminum battery, though in other cases, they usually died after just 100 charge-discharge cycles. The Stanford-created battery was able to withstand over 7,500 cycles without any loss of capacity, whereas most lithium-ion batteries last 1,000 cycles. According to the researchers who created it, this is the first time an ultra-fast aluminum-ion battery was constructed with stability over thousands of cycles.
Aluminum-ion cells are cheaper lithium-ion. They're also not as flammable and have a high storage capacity, all of which are reasons that researchers have spent decades trying to develop affordable aluminum-ion batteries that meet the needs of consumers.
One of the challenges has been finding materials that can produce enough voltage after multiple charge and discharge cycles.
