They created a battery that can last for centuries

Battery pack can have a huge impact on key consumer products such as smartphones and tablets, and the growing popularity of electric cars - if they were not so easily susceptible to damage, says io9.

In an attempt to address this, researchers from Stanford University have developed a battery that can repair itself when recharging, which in turn significantly increases life.

The anode of the so-called. Healing battery consists of silicone polymers, which act as chemical patches, filling all cracks, obtained as a result of dilution and overcharging of the battery. The capacity of the new battery is many times greater than that of any conventional cathode. If you gather with such ordinary cathode, the new battery can store 40 percent more energy; if you gather with other cathode high capacity, the total storage of energy can be doubled and tripled.

The new battery can withstand up to 100 cycles of recharging, but scientists from Stanford this still is not enough. They want to increase the capacity of 500 cycles for mobile devices and up to several thousand electric cars.

According to Professor Ind Cui, he and his team "just beginning" development work in this field and hope that ultimately will be able to create batteries that can withstand enormous number of cycles before they are fully discharged.
