But, as published in the current issue of the journal Angewandte Chemie International (1), a team of scientists from South Korea has discovered a way to bulk produce these nano-silicon sponges so that they can withstand repeated charging and discharging cycles. Not only does this new material have a much higher charge capacity, the nature of its nano-structure allows for rapid charging and discharging.
The storage capacity of current generation lithium ion batteries remains a bottleneck for the widespread adoption of electric cars due to a perceived limited driving range. Although we could argue whether a 100-130 mile range really is that much of a limitation or not, perhaps the better solution is to be able to ignore that argument altogether by increasing battery capacity.
