New Battery with High Charging Capacity
Battery technology has not seen a significant upgrade for quite some time, but that could be changing now thanks to researchers at the University of California, Irvine who have discovered a new battery with high charging capacity.
The discovery happened by chance, one of the researchers coated gold nanowires in a manganese dioxide shell and encasing the assembly in an electrolyte made of a Plexiglas-like gel.
Nanowires have been long sought for use in battery technology as they are thousands of times thinner than a strand of human hair, are highly conductive and feature a large surface area for the storage and transfer of electrons. The problem is that they are very fragile and do not hold up after repeated discharging, recharging, or cycling.
With this new discovery, the nanowires are reliable and resistant to failure. With this new coating the battery was cycled hundreds of thousands of times without losing any capacity. This research proves that a nanowire-based battery electrode can have a long lifetime and that a battery that does not need to be replaced is one step closer to reality.
