U.S. battery maker Aquion Energy Inc. filed for chapter 11 protection yesterday and said that it was in talks to sell substantially all of its operating assets, Reuters reported. Aquion, which makes saltwater batteries for use in electricity grids under the Aqueous Hybrid Ion brand, also said that it laid off 80 percent of its workforce and paused all factory operations. Several potential buyers have shown interest in the company and are conducting due diligence under non-disclosure agreements, Aquion said. Pittsburgh-based Aquion listed assets and liabilities of between $10 million and $50 million in a filing with the U.S. bankruptcy court in Delaware.
