Batteries Made from Trees A Startup's Plan for Sodium-Ion Anodes

Lucas and Luna dive into the chemistry and economics of sodium-ion batteries, focusing on one startup's surprising choice: using carbon from wood waste as the anode material. The episode opens with the announcement that a Swedish battery company has secured $100 million in Series C funding to scale production of sodium-ion cells for grid storage. Lucas explains why sodium-ion matters — sodium is abundant and cheap compared to lithium — and why the anode material has been a bottleneck. Luna questions whether wood-based carbon can compete on performance and cost. The hosts walk through the startup's process: how they pyrolyze paper-mill waste into hard carbon, the energy density trade-offs, and the potential to undercut lithium-ion on cost by 30-40% for stationary storage. They also touch on the bigger picture: this is one of several startups racing to commercialize sodium-ion for applications that don't need the highest energy density. The listener learns exactly why the anode is the hardest piece and how one company thinks wood waste is the answer. #SodiumIon #BatteryTechnology #GridStorage #WoodWaste #HardCarbon #Anode #EnergyStorage #ClimateTech #Startup #SeriesC #SwedishTech #RenewableEnergy #LithiumAlternatives #Business #Technology #FexingoBusiness #BusinessPodcast #ClimateTechPodcast Keep every episode free: buymeacoffee.com/fexingo
