The Silicon Valley startup shutters its building as funding dries up, but the world may not have seen the last of its proprietary formula for lithium-ion batteries.
Menlo Park, Calif.-based Imara is looking for buyers of its patents and technology, after abruptly shutting its doors yesterday. The company made rechargeable lithium-ion batteries that used nickel manganese cobalt chemistry.

Silicon Valley Bank has taken possession of the company's five to eight other patents and technology that are in process, Maguire said. The company's research and development team is "working to package those up" for potential buyers. Those patents are related to its scientists who have the "know how, the trade secret-type stuff," he said.
