In theory, lithium-metal batteries have the potential to store huge amounts of energy at low cost but attempts to develop them in practice keep failing because of a persistent problem. Now, it seems that a team of engineers is very near to solving the problem.

The need for high-capacity energy storage is growing, especially for use with wind turbines, smart grids, and electric vehicles. However, the technology to meet this demand in a stable, effective, and affordable way is lagging.

The idea of lithium-metal batteries is not new – it has been around for more than 100 years.

Unlike their cousins – the lithium-ion batteries that are now widely-used in consumer electronics – lithium-metal batteries have not taken off because their development has been stuck at a practical problem that causes them to overheat and even catch fire.
