2022-03-24 Thermophotovoltaic Battery R & D @T.U. Madrid
This sounds promising. I’m puzzled by what is used for the photovoltaics and how it can handle such high temperatures – 1000 deg C. The glowing ferrosilicon generates a lot of infrared so in order to have 40% efficiency the photovoltaics must convert a lot of the IR to electricity. https://www.pv-magazine.com/2022/03/23/latent-heat-thermophotovoltaic-battery-for-renewables-storage/ I know a bit

2021-06-22 Battery Storage Information Article
This article gives good information about various types of BESS. Mentions FERC order 2222. Flow batteries. Talks about green hydrogen, electrolyzers, fuel cells and round trip efficiency. Other battery uses. https://www.tdworld.com/distributed-energy-resources/energy-storage/article/21160307/energy-storage-grows-up
2021-05-17 Li-Ion Competitors: Flow, Zinc, Sodium Etc.
This good blog has many links to other articles about competitors to Li-Ion AKA LIBs. But near the end it explains why LIBs may be very difficult to compete against. It points out that as more renewables make up the grid, there is more demand for medium (8 to 24 hours) storage and long term

2021-03-26 Breakthrough Liquid Metal Battery – Sadoway & AMBRI
A tutorial about Ambri’s liquid metal batteries “If you want your battery to be dirt cheap, make it out of dirt!” – Donald Sadoway https://youtu.be/2BlyDVb5L3U LMBs are different. Sadoway says that the designers of Lithium-ion Batteries have to guard against thermal rise; The designers of liquid metal batteries have to guard against thermal fall.
