Battery can be charged 40.000 times and lasts 10 years

The big problem with gadgets is the battery. Even if they start lasting enough, after 12 months they begin to weaken. But a new material can change that.

A team of researchers at Stanford University developed a new battery electrode that can survive 40,000 cycles of load. This is 100 times more than a standard battery Li-ion, and enough to make it usable by a period of 10 to 30 years.

How does it work? It all boils down to the material with which it is made: the copper hexacyanoferrate. The structure of the material allows the ions, which give energy to the battery, and disembarking from the electrode more easily. And it's pretty tough, then it falls apart at a rate much lower than Li-On batteries. This means that it can be loaded faster, and still last for years. Great!

Just one problem. A cathode high voltage needs a very low anode voltage. Only they have not discovered that part, so for now it's impossible to create batteries sealed and ready for commercial use. But this is the next phase for the team. Couple this with the battery technology that load 10 times faster and have a capacity 10 times greater, and I'll be happier with my gadgets.
