Apple seeks patent for battery that could run devices for weeks

A recent patent application filed by computer giant Apple reveals what might be the company’s next big thing: hydrogen batteries.

Hydrogen batteries work by splitting water into its core chemical components, then using those chemicals to generate electricity, but for many years the reaction was too volatile for most commercial applications.

Scientists announced in 2008 that they had finally discovered a way to conduct the reaction in a much smaller container, free from the corrosive effects that marred previous attempts. They also learned how to create hydrogen batteries that can store vast amounts of electricity in very small containers.
