Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. However, in the PNNL team’s demonstration, the freeze–thaw mechanism of the molten salt is able to circumvent that problem.

That’s because liquified gas has a lower viscosity than carbonate-based electrolytes, which allows the lithium salt to move from one electrode to the other at a faster rate, shortening the time it takes to recharge the battery. Emily Waltz Mining leaves behind piles of waste after the commercially viable material is extracted.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. They gradually lose capacity with each discharge and recharge cycle, and they can be fire hazards.
