Researchers in Australia have developed a polymer-based electrolyte material that significantly improves sodium metal battery design, This new design is intended to replace lithium ion batteries in applications such as electric vehicles and cell phones. Traditionally sodium batteries have provided less energy density and fewer charge/discharge cycles than lithium ion. Sodium batteries built with this …

Iron-air batteries are big and heavy, but relatively cheap per kilowatt-hour. Good for grid storage.Can discharge over a much longer timeframe than lithium-ion. A one megawatt system capable of 100-hour discharge time requires about one acre of land. They also offer a “grid modeling toolkit” which is software to model power grids. Website

When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries’ anodes get sluggish, holding less charge and draining energy quickly. To improve electrical performance in the extreme cold, researchers reporting in ACS Central Science have replaced the traditional graphite anode in …

For stationary applications (mostly power shifting) the question is can Zinc-Bromine from EOS (EOSE) be good enough (ie do they work, can they be produced domestically from abundant materials)? The big negative with Zinc-Bromine seems to be the round trip efficiency is only ~80%, is this a deal breaker? EOS is so cheap it’s a …
