More Details on Fast-Recharge Batteries

This week's New Scientist has a few more details about the rapid-recharge battery technology developed by Altair Nanotechnology we mentioned recently. Two interesting tidbits from the piece: the improved charge rate comes from increasing the effective surface area of the anode at the nanoscale; and the technology for improving the charge rate also translates into faster discharge rates, making the new type lithium-ion batteries suitable for rapid-discharge uses.

The new design also gives the batteries a greater reuse life, up to 20,000 recharges before becoming useless, as compared to ~400 charging cycles for current Li ion batteries.
