So, I learned a lot this #SolarPunkSunday! #BokashiComposting , #LacticAcidBacteria uses, new breakthroughs with #Sandbatteries, #Piezoelectrics, and #Renewables! And all the sharing of tips and tricks and events! I hope folks join us next weekend! Share your #RepairCafes, #ToolLibraries, #CommunityBuilding, #Gardening pics, #SolarPunk stories and art, etc., etc. Together we can BUILD a better future!

Fast-charging #SodiumIon battery uses anodes made from trees
By C.C. Weiss
June 09, 2024"A month after #NatronEnergy began its first-of-kind sodium-ion battery mass production, Swedish sodium-ion developer #Altris has identified a means of making the LithiumFree batteries even more sustainable. Together with partner #StoraEnso, it's adapting tree pulp-sourced carbon toward use as an anode material.
"A byproduct of wood pulp manufacturing, #lignin has long been investigated for possible use as a more sustainable electrode material. Finnish renewable materials company Stora Enso made headlines in 2022 when it partnered up with Swedish battery manufacturer #Northvolt toward using its proprietary #Lignode material in lithium-ion battery anodes. Stora Enso describes Lignode as a hard carbon material refined from lignin.
"By teaming with Altris, Stora Enso looks to go even more sustainable while further localizing the European battery supply chain. As we looked at when Natron Energy kicked off production a few weeks ago, sodium-ion batteries eliminate the need for rare minerals like lithium, cobalt and nickel, relying on abundant sodium that can be sourced locally without harmful #mining. "

Feb 20, 2026 06:59 AM EST"A new sustainable method turns discarded #MobilePhoneBatteries and industrial lignin into a powerhouse material for #SodiumIon batteries.
"It is a stunning example of circular economy innovation. Rather than letting these materials sit in #landfills or go up in smoke, the team from China is giving the waste a high-tech second life.
"When tested as a sodium-ion battery anode, this composite of #nickel-#cobalt sulfides and #lignin-derived carbon delivered electrochemical results."

What's on my mind? Why, thinking about how #TrumpSucks is the #AntiSolarPunk! He's trying to get rid of solar, making the super-rich even richer, cutting funding to libraries (#LibraryOfThings), causing more #FoodInsecurity and #HousingInsecurity, allowing corporations to destroy #NaturalPlaces, etc., etc. What #SolarPunk promotes is everything that Trump is trying to destroy!
