Are liquid metal batteries a promising energy storage technology?

With a long cycle life, high rate capability, and facile cell fabrication, liquid metal batteries are regarded as a promising energy storage technology to achieve better utilization of intermittent renewable energy sources.

Are liquid metal batteries a viable solution to grid-scale stationary energy storage?

With an intrinsic dendrite-free feature, high rate capability, facile cell fabrication and use of earth-abundance materials, liquid metal batteries (LMBs) are regarded as a promising solution to grid-scale stationary energy storage.

What are rechargeable liquid metal batteries?

One representative group is the family of rechargeable liquid metal batteries, which were initially exploited with a view to implementing intermittent energy sources due to their specific benefits including their ultrafast electrode charge-transfer kinetics and their ability to resist microstructural electrode degradation.

What is a liquid metal battery?

A liquid metal battery is a cell containing liquid metal electrodes. In this Outlook, we comprehensively summarize the two types of cell designs: (1) batteries with only liquid metal anodes; and (2) batteries with both liquid metal anodes and cathodes. Figure 1 summarizes the appealing features of liquid metals for energy technologies.

Are liquid metal batteries a novel energy system?

Intermediate and room-temperature liquid metal batteries, circumventing complex thermal management as well as issues related to sealing and corrosion, are emerging as a novel energy system for widespread implementation.

How are liquid metal batteries different from high-temperature batteries?

Different from high-temperature liquid metal batteries invented at General Motors and Argonne National Laboratory 50 years ago, liquid metal batteries were revisited based on the chemistry of fusible alloys.
