The limited capacity of accumulators is one of the major hurdles for the introduction of electric propulsion of vehicles. A lot of energy and intellect and money is thrown at the problem, with promising results.
A Korean team has discovered a method to increase the storage capacity of anodes in Lithium-Ion accumulators quite dramatically. The capacity of a cell is proportional to the number of ions that can be stored in anodes when charged. They have found a way to use silicon to create highly porous structures that can withstand the stress of charging and de-charging. Zoomilife is very optimistic, but even a 3-4 fold increase would propel EV’s into the mainstream of car manufacturing.
