A government decision halted the operations of a Hungarian battery supplier after a nearby watercourse became discolored.

Production at Volta Energy Solutions Hungary Kft. has been suspended due to environmental concerns following reports of water discoloration. The decision came after inspections revealed potential hazards. The company, owned by Solus Advanced Materials Co., Ltd., specializes in manufacturing copper foil for lithium-ion batteries. They stated that no contaminants have been released since October 31 and are actively addressing the leak's source while keeping authorities informed.
