An Irish company has developed a long-life battery that stores electrical energy in liquid form. Red-T, the company behind the flow battery technology, said its battery can store energy for much longer than conventional batteries and could potentially provide electricity for people in remote locations. The battery relies on a vanadium electrolyte to transport electrons through the battery cell. John Ward, chief executive officer of Red-T, explained to the The Engineer that vanadium is ideal because its unique valences make it very stable. He said: 'Batteries such as the lithium-ion bat- tery seen in electric cars can charge/discharge around 1,500 times. After this they degrade very quickly and they cannot be re-used. They are also not great with partial charges.
