•Nanobatteries are created by coating the surface of an electrode with nano-particles. This increases the surface area of the electrode, thus allowing more current to flow between the electrodes and the chemicals inside the battery.
•The nanosurface hold the batteries’ electrolytes away from the reactive metal when no power is needed, and releases it when its time for the battery to turn on.
•This allows the battery to have an extremely long shell life when compared with the current traditional battery.
•Nanotechnologists are trying to reinvent the way that the batteries’ electrodes work by using silicon nanowires, rather than carbon, to store the lithium ions in the anode.
•Silicon can hold a large amount more ions than lithium can. Interestingly, silicon is so great at storing lithium ions that during charging it actually swells and contracts during use. This property of the silicon nanowires allows the anode to absorb and release lithium without breaking down, and so when the battery is charging, it can expand to four times its original size.
•This means that these nanobatteries could be used to greatly increase the amount of time electronics have before they need to be recharged again.
•For example, if your laptop currently gets two hours of battery life, using these nanobatteries they would get almost 20 hours
