Electrochemical energy storage devices

This invention describes a battery that uses liquid materials for its electrodes and electrolyte, contained within a housing and a special crucible or coating. It's designed to manage internal pressure and control the interfaces between its liquid components, which helps improve its performance and lifespan, especially for high-temperature batteries.

Why it matters: In 2014, liquid metal batteries were largely experimental, facing significant engineering hurdles for high-temperature containment and interface control. Today, the urgent demand for grid-scale energy storage has spurred advancements in high-temperature materials and manufacturing, making the practical implementation of these battery types more viable.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedHigh-temperature materials, molten salts, liquid metals
