Matt ‘Undecided’ Farrell YT Channel From print OCR Quote: “”The first production under the Naxtra brand will be of a new sodium-ion battery with an energy density of 175 watt-hours per kilogram, nearly equivalent to the lithium iron phosphate (LFP) batteries popularly used in electric vehicles and grid energy storage systems. Sodium-ion batteries may have

Matt / Undecided tells us about the current state of the sodium ion battery market. Some of the new developments.
The cost of Lithium-ion batteries is still dropping and sodium-ion batteries use even lower cost materials, so it’s likely that the long duration energy storage – LDES – will not catch up for some time. One LDES is green hydrogen, and hydrogen LDES systems seem to have stagnated, partly due to the falling prices of

Article about recycling EV batteries versus using EV batteries for stationary storage. At this time, recycling is not very efficient. Quote: ““Today we are not very good at recovering metals, loosing almost all the lithium, silicon, phosphorus, aluminum, and graphite, while recovering only copper, cobalt, and nickel which are more expensive,” he says.”” This suggests

This link to the article is supposed to be free, and *not* behind a paywall. This well-researched article is a good article, with some statements that are disputable. One example is that they state that lithium batteries are flammable. The LFP cells now used in battery storage systems are low to not flammable. There are

Natron enters low volume production. The article says 70 Wh/kg, less than half of lithium. “”…advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative…”” https://newatlas.com/energy/natron-sodium-ion-battery-production-startt/
This article gives good explanations of how batteries are made and what advantages and disadvantages they have. The top three battery chemistries coming soon to EVs – and none of them are solid-state
The EU is going to prohibit new gas cars by 2035. But they question whether there will be enough batteries for EVs in 2035. They mentioned Lithium iron phosphate and sodium ion batteries. But they failed to state the obvious! The law doesn’t say everyone must buy a battery EV. They failed to even mention

Watson’s Buzz Beeper I built this Buzz Beeper to find out if an audible tone could be used for sending simple commands, like turn on. Recently I built a microphone preamp with a bandpass filter that can detect my whistle. But it can be triggered by loud noise. So how about I generate a tone

Article gives Wh/kg for new LFP and cobalt free batteries. The recent excessive high price of nickel is causing the industry to reduce or avoid it. Also eliminating cobalt. The future batteries may become dependent on phosphate, of which 70% of the world supply is in Morocco. https://cleantechnica.com/2022/03/31/lfp-battery-news-is-the-end-of-nickel-in-sight/
