What could be the Next Breakthrough in Rechargeable Batteries After Lithium-ion Batteries?

was considered a breakthrough in rechargeable batteries industry when it was first released by Sony in the early 1990s as it produces high operating voltage and they have large energy density. It is so good that it is able to replace the nickel metal hydride batteries (NiMH) which was used beforehand.

There are a lot of usages of the lithium-ion battery especially in the electronic world such as it is used to power up the latest Samsung Galaxy smartphones and thus enables the device to have slim design.  However, in the recent years, the popularity has gone down as the lithium-ion battery life is shorter for modern portable devices and also providing limited driving range of electric cars if compared to gasoline powered vehicle. On top of that, there are cases whereby the device powered by lithium-ion batteries has exploded although it is not many, and thus raising safety concern.

As a result, there has been effort in trying to find out the next breakthrough which could replace the current lithium ion battery. There have been experiments in the lab which is using emerging chemistries such as lithium-sulfur or lithium-air which could potentially able to revolutionize portable energy storage applications. However, they are in the research stage which there is no guarantee that they can be released to the public to use.
