Finding a new way to store power in our mobile devices has been a problem for quite some time. We’ve been stuck with Lithium-Ion batteries for a while now, and unless a device is using ULV or is a netbook, chances are the battery life could be a lot better. There’s been promises of several types of new battery tech recently, but none has really taken off. Now yet another new possibility has come as the replacement for the Lithium-Ion.
The new technology is called Metal-Air Ionic Liquid. It works by conducting electricity through an ionic liquid salt. Without getting into too much detail, it means that batteries can be made with metals heavier than the zinc used in zinc-air batteries. To put it into perspective to Lithium-Ion batteries, one kilogram or MAIL can hold about 11 times more watt-hours than the same weight of Lithium-Ions. The main idea of MAIL batteries will be for cars, but they could easily benefit our laptops can netbooks.
The promise of being able to hold up to about 11 times the charge of a Lithium-Ion battery could easily mean that our laptops and netbooks can last for close to a day, or even multiple days. It will probably be a while before we start seeing anything with MAIL batteries, but it might be worth the wait. With Intel pushing it’s ULV chipsets, it wouldn’t be all that surprising to see standard laptops running for days at a time when combined with MAIL. We can only hope that this, like so many other battery improvements, doesn’t end up falling away into obscurity or becomes to unfeasible.
