|A water-based, rechargeable battery|

In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves a question: Why not simply use water as an electrolyte? Water is cheap, in abundant supply, doesn’t burn and can conduct ions. But it has one major drawback: It is only chemically stable up to a voltage of 1.23 volts. In other words, a water cell provides three times less voltage than a customary lithium ion cell with 3.7 volts, which makes it poorly suited for applications in an electric car. A cost-effective, water-based battery, however, could be extremely interesting for stationary electricity storage applications.

A research team has created a thermoelectric material with promising performance at room temperature. Ytterbium silicide is a good electrical conductor. It also has a high Seebeck coefficient thanks to Kondo resonance (fluctuation of f-electrons), which increases its power factor. Its layered structure further promotes the thermoelectric effect by blocking heat conduction. This non-toxic, room-temperature thermoelectric material is competitive with conventional bismuth telluride, and could be used for power generation or refrigeration.

The electrical grid in the contiguous United States is a behemoth of interconnected systems. If one section fails or is sabotaged, millions of citizens could be without power. Remote villages in Alaska provide an example of how safeguards could build resilience into a larger electrical grid. These communities rely on microgrids -- small, local power stations that operate autonomously.
