Semi-solid battery developer 24M has developed a novel dual electrolyte system that makes it possible to manufacture Li-ion battery cells with compositionally distinct electrolytes—anolytes and catholytes—at scale, enabling next-generation chemistries capable of providing industry-leading energy density (more than 350Wh/kg), while improving cycle life, safety and cost. 24M DES 24M CTO Naoki Ota will present the Dual Electrolyte System at the International Battery Seminar & Exhibit in Fort Lauderdale, Florida later this month. The 24M SemiSolid electrode platform ( earlier post ) provides the foundation for its Dual Electrolyte System, significantly improving overall manufacturing capital efficiency, while allowing distinct approaches to cell design and chemistry. The novel 24M cell architecture uses an ionically conductive, non-permeable separator to isolate the anolyte from the catholyte, while eliminating solid-to-solid interface issues that have plagued full solid-state approaches to date. 24M says that its work with numerous world-class materials manufacturers has shown this approach […]
