Lithium-ion batteries with silicon electrodes allow batteries to store much more energy than other batteries. The problem, however, is that the batteries degrade and become unusable fairly quick. Fortunately, scientists develop a battery that repairs the damage done to it.
One of the major limitations in tech today is the storage capacity of batteries. Electric cars, solar generators, your cell phone – the performance of all of them is ultimately limited on how much charge a battery can hold. One of the most promising materials for use with lithium-ion batteries is just plain old silicon. Silicon is capable of holding a lot of energy while the battery is charging, lengthening its life.
