Lithium-Ion Batteries Have been a Boon for the Modern World -- they've Replaced the Heavier, Single-Use Alkaline Type in Everything from Wristwatches to Jumbo Jets. Unfortunately, these Rechargeable Cells are Already Struggling to Keep Up with our Ever-Increasing Energy Needs. But, a New Type of Aluminum-Ion Battery Developed at Stanford University, is Not Only Less Explode-y than Lithium but also, Can be Built at a Fraction of the Price and Recharges Completely in just Over a Minute. Best of All, "Our new battery won't catch fire, even if you drill through it", Stanford Chemistry Professor, Dai Hongjie, Boasted in a Recent Release. Unlike Earlier Aluminum Batteries, which Generally Failed after Only about 100 Recharge Cycles, Stanford's Prototype, Can Cycle More than 7,500 Times without any Capacity Loss -- 7.5 Times Longer than your Average Li-Ion.
The Aluminum-Ion Cell, Isn't Perfect (Yet), as it Can Only Produce about 2 Volts, Far Less than the 3.6V that Lithium-Ion an Muster. Plus Aluminum Cells only Carry 40 Watts of Electricity per Kilogram, Compared to Lithium's 100 to 206 W/kg Power Density. "Improving the cathode material could eventually increase the voltage and energy density", Said Dai. "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."
