Scientists have developed a stretchable, breathable, lead-free perovskite/polymer nanofiber composite for hybrid triboelectric and piezoelectric energy harvesting. Essentially a fabric that can produce electricity from movement of the wearer. https://onlinelibrary.wiley.com/doi/10.1002/adma.202200042 Source: Ebatco Nano newsletter
Engineers at MIT and the Technical University of Munich have designed a new kind of glucose fuel cell that converts glucose directly into electricity. The device is smaller than other proposed glucose fuel cells, measuring just 400 nanometers thick, or about 1/100 the diameter of a human hair. The sugary power source generates about 43 …

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 …

Focus on increasing efficiency of the car resulting in more range and faster recharge by using a smaller battery pack. Increased efficiency also allows onboard solar cells to contribute significant miles per day of recharge. The company has over 25,000 reservations (it costs $100 to reserve). Price ranges from $26K – $47K depending on size …

Along the lines of heat, there is also thermal storage and there is a very early stage company in Israel called Brenmiller (BNRG). A recent find, still need to learn more. Website
Heliogen (HLGN) which makes solar concentrators also known as CSP (Concentrating Solar Power) – arrays of mirrors that concentrate sunlight. They can use the resulting heat directly for industrial process that require heat, or to generate electrical power, or to create green hydrogen for fuel. Website From the National Renewable Energy Laboratory (NREL) report Winter …
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 …

Mobility needs a supply of lithium and Standard Lithium (SLI) may have a solution, but they will have to raise money to build a plant. Website
