2021-07-04 UEP’s BESS Lowers Costs $50/kWh

This is very interesting. A BESS that takes up less room than a lead-acid battery, can hold more kWh’s and is cheaper. They have a demo 2 MWh system in racks indoors.

2021-05-07 Relithiation To Make Old Batteries Like New

If the old cells were made easier to take apart and reassemble it would be helpful. I think that someday the battery makers may do what Eagle Picher did for batteries on spacecraft. There is a container of electrolyte inside the battery. To activate the battery a small charge blows the electrolyte out of the

2021-04-03 Sand Battery To Store Heat

This is a novel idea. Heat up sand during the daytime with solar energy. After sunset circulate the hot sand through a steam generator to run a turbine and generator. Short 2 min video.

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 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.

2021-02-28 3 kW Solar + LiFe Battery For Under $3000

This is the kind of setup I would like to have. I would use it to run my heat pump / air conditioner and maybe a few other things like the microwave oven. And it would be used for charging my EV when it’s at home. The two solar PV panels are 800 watts total.

2021-02-25 New Home Hydrogen ‘Battery’ Good For 3 Days

This was developed by the University in Australia. It seems to be two or three separate parts. It takes solar electricity and converts it to hydrogen. The H2 is stored in metal hydride ?cartridges? Then the H2 is made into electricity by fuel cells. It says that it also has a 5 kWh lithium battery

2021-02-18 EV Batteries Charge In 5 Minutes

They say the problem is ‘range anxiety.’ The batteries can charge 100 miles in 5 minutes. This is one of Hashem’s videos. The references are in the pinned comment.

2021-02-13 Article Talks Trash Re: EVs and Lithium Batteries

My replies to article cited by an “electrical engineer with 34 yrs experience”. << Ned Goldston Thanks for the link to the article. The article is written with false information (e.g. li-Ion batteries cannot be recycled), the reference used is at least 8 years out of date, and the most telling is the last

2020-11-17 Tesla Batteries And Supply Constraints

The manufacturing of Electric Vehicles and grid scale storage are constrained by the amounts of batteries that can be supplied by the battery makers around the world. The early Tesla EVs used the ubiquitous 18650 lithium ion cells, something like 6000 per vehicle. In order to reduce costs and weight Tesla went to the larger

2020-11-11 Redox Flow W/O Vanadium; Chinese Anti-Capitalism Economics

Researchers have come up with a redox flow battery that uses organic chemicals in place of toxic and expensive vanadium. They cost less than half as much, too. We need to have millions of these made and deployed over the whole world to solve the intermittent renewables problem. Chinese Anti-capitalist economics The capitalist way
