TOKYO -- Fast-charging energy storage devices that outlive lithium-ion batteries will have a new distributor in Asia, where they are expected to find a broad range of uses including electric vehicles and power infrastructure.

Japanese trading house Marubeni this week took a stake of several percent in Estonian startup Skeleton Technologies, which develops ultracapacitors. Marubeni will serve as a sales agent for Skeleton's ultracapacitors in Asia, including Japan, and work with customers to develop products suited to their needs.
