AAA, D, CR32, 1.5V, 9V. It seems like we have been using batteries to store energy forever! Everything takes batteries. Containers of chemicals that keep that power all bottled up until we need it. Well there is finally a new energy storage technology that just might replace the common battery, and maybe even the common hard drive. The new magnetic battery can store more power and charge amazingly fast! The "spin battery" is charged by applying a powerful magnetic field to nano-magnets contained in a device called “magnetic tunnel junction”, or MTJ. This technology could one day be used in hybrid or electric cars, medical equipment or off-grid energy applications. Cool stuff, man!
