Triangle molecule charges up aluminium batteries
Cathode made from triangular macrocycle hosts complex metal cations in a rechargeable aluminium battery
Scientists have designed a triangle-shaped molecule to make the first rechargeable aluminium battery, getting one step closer to cheap and powerful batteries that could outperform lithium-ion systems.1 The battery – which can be recharged thousands of times – is the first to run on aluminium cations. This solves a conundrum in existing aluminium-ion systems: they work with complex anions and consume a lot of electrolyte.
