![]() Those pesky dendrites are the bane of lithium-ion batteries. NMR measurements reveal that the electrolyte salts responsible for the excellent lithium morphology are slowly consumed during cycling.” The liquid electrolyte enables smooth dendrite-free lithium morphology comprised of densely packed columns even after 50 charge - discharge cycles. “Here, we show that anode-free lithium-metal pouch cells with a dual-salt LiDFOB/LiBF4 liquid electrolyte have 80% capacity remaining after 90 charge–discharge cycles, which is the longest life demonstrated to date for cells with zero excess lithium. Many researchers believe that for lithium-metal cells, the typical liquid electrolyte used in lithium-ion batteries must be replaced with a solid-state electrolyte to maintain the flat, dendrite-free lithium morphologies necessary for long-term stable cycling. “Cells with lithium-metal anodes are viewed as the most viable future technology, with higher energy density than existing lithium-ion batteries. Here’s the abstract of that research report: Research published by Dahn and his team in the journal Nature Energy on July 15 reveals they have created new lithium-ion pouch cells that may outperform solid-state technology battery. ![]() It also reassures the public their shiny new electric cars aren’t going to explode in the garage, as recently happened to the owner of a Hyundai Kona EV in Canada. That in turn means electric car manufacturers can make simpler, less costly cooling systems for their battery packs, driving down the cost of EVs. In addition, solid-state batteries are less like to catch fire or explode if they get too hot. Well, if someone can crack the final code for commercially viable cells. Solid-state batteries are believed to be cheaper to produce, have higher energy density, and have a longer lifespan than conventional lithium-ion batteries. For years, the Holy Grail of battery research has been making solid-state battery cells that replace the liquid electrolyte in conventional cells with solid materials.
