This liquid metal battery could revolutionize energy storage

Ambri, a company spun out of MIT Lab (Massachusetts Institute of Technology), the large-scale deployment of liquid metal batteries will begin. A promising solution for storing intermittent energy from renewable sources.

One of the current challenges for research is to find a solution for storageRenewable energyRenewable energybecause intermittent production rarely matches demand. battery lithium-ionbattery lithium-ion are too expensive and riskySwellingSwelling Too much for this type of use. Many researchers are working on alternatives, such as molten salt batteries, metal-air batteries or simply sand.

Embry Company, founded by researchers from MIT (ButSAchusets Institute of Technology), has already made headlines for its molten salt battery. However, it has announced the next deployment of a new battery based on liquid metals, antimonyantimony at calciumcalciumFrom 2024 onwards.

non memory effect battery

Batteries are made of three layers of liquids that can overlap due to different densities, such as oil and vinegar. is the lowest layer cathodecathode, is made of molten antimony (Sb). l’anodeanodeAt the top of the heap, is calcium (Ca). The middle electrolyte is composed of a solution of calcium chloride (CaCl2). During discharge, the anode releases calcium ions, which pass through the electrolyte Metal AlloysMetal Alloys calcium-antimony at the cathode, until the anode is completely consumed. Reverses the charging process.

The simplicity of the process avoids the memory effect of the battery, and there is no risk of fire. It should retain 95% of its capacity after 20 years of operation, a figure impossible to achieve with lithium-ion batteries. Moreover, its cost should be much lower than that of the latter. Ambri’s batteries cost between $180 and $250 per kWh, a price expected to drop to $21 per kWh by 2030. For comparison, a 100 MW installation with lithium-ion batteries costs $405 per kWh. The first full-scale test of the battery will be a 300 kWh installation in Colorado in partnership with Accel Energy early next year.
