The Laboratory for Energy Storage and Conversion at the University of Chicago, led by Prof. Shirley Meng, has developed the world's first anode-free sodium solid-state battery. This breakthrough innovation aims to create inexpensive, clean, and fast-charging batteries for electric vehicles and grid storage. By utilizing sodium instead of lithium, the battery becomes more affordable and environmentally friendly. The research, published in Nature Energy, showcases a new sodium battery architecture with stable cycling for hundreds of cycles. The team's approach involves a novel current collector made of aluminum powder that can flow like a liquid, addressing challenges typically faced by anode-free batteries. This advancement not only contributes to the science of battery technology but also plays a crucial role in transitioning the global economy away from fossil fuels. The ultimate goal is to provide a variety of clean and cost-effective battery options to store renewable energy efficiently. Prof. Meng and her team have filed a patent application for their work, emphasizing the potential impact of their innovation on the energy storage landscape.

21 comments“ The lithium commonly used for batteries isn’t that common. It makes up about 20 parts per million of the Earth’s crust, compared to sodium, which makes up 20,000 parts per million.
This scarcity, combined with the surge in demand for the lithium-ion batteries for laptops, phones and EVs, have sent prices skyrocketing, putting the needed batteries further out of reach.”

Sayeth Wikipedia, "Instead, it creates a metal anode the first time it is charged."
Ok. I'm still not entirely clear on it but it makes some kinda sense.
Chromium is 5 times more abundant than Lithium in earth crust (0.01% vs 0.002%). Better, but not that much ?
"Regular" sodium-ion batteries with prussian blue has, it seems, the great advantage of not using any scarce elements. It would be nice to have a comparison between this solid state chemistry and the regular one.
Lithium extraction is also environmentally damaging, whether from the … brine extraction that pumps massive amounts of water to the surface to dry.
can you use existing factories and manufacturing techniques or do you need to invent or build those. we've started hearing about solid state batteries about 15 years ago and we still dont have any at a big enough scale. if solid state batteries do takeoff it will probably takeoff first in electric aviation and supercars which can hide the cost due to a more expensive products and the need for higher density
