Battery technology patents and specialist testing equipment are being offered for sale by business restructuring group BDO, which is handling the assets of Oxis Energy after the company went into administration—a step that precedes sale or liquidation—on May 19. The UK-based company collapsed after failing to secure fresh investment, with the loss of 60 jobs, many of them held by highly experienced engineers.

The sale includes 43 patent families covering technologies such as quasi solid-state batteries, electrolyte systems for lithium-sulfur cells, methods of lithium-sulfur cell construction, and positive and negative electrodes. Specific European patents include a rechargeable lithium-sulfur battery with high specific energy, connecting contact leads to lithium-based electrodes, and a battery management system.
