Its key takeaway is that bulk ionic conductivity is no longer the main obstacle for sulfide electrolytes; interfaces, mechanics and stack pressure now dominate the remaining development effort, and most 2026 evidence is still at preprint stage.","version":1,"published_at":"2026-10-30","updated_at":"2026-10-30","stats":{"words":3533,"citations":61,"claims":29,"timeline":18,"benchmarks":2,"open_problems":5,"key_papers":15,"glossary":10},"verification":{"status":"verified","method":"automated figure and citation-relevance triage against cited abstracts, targeted AI review with web checks of flagged statements, and a close-out pass hedging or removing unconfirmed statements; automated citation resolution","claims_checked":29,"issues_fixed":3,"verified_at":"2026-10-30"},"ai_assisted":true,"price":{"usd":"0.20","protocol":"x402","network":"eip155:84532","asset":"USDC"},"url":"https://space-kitty.com/dossiers/next-gen-batteries","preview_url":"https://space-kitty.com/api/v1/dossiers/next-gen-batteries/preview","purchase_url":"https://space-kitty.com/api/v1/dossiers/next-gen-batteries","toc":[{"level":2,"text":"Executive summary","anchor":"executive-summary"},{"level":2,"text":"Background and core concepts","anchor":"background-and-core-concepts"},{"level":2,"text":"Timeline of key milestones","anchor":"timeline-of-key-milestones"},{"level":2,"text":"State of the art","anchor":"state-of-the-art"},{"level":3,"text":"Inorganic solid electrolytes: sulfides, oxides and halides","anchor":"inorganic-solid-electrolytes-sulfides-oxides-and-halides"},{"level":3,"text":"Interfaces, interphases and mechanics","anchor":"interfaces-interphases-and-mechanics"},{"level":3,"text":"Lithium-metal anodes and dendrites","anchor":"lithium-metal-anodes-and-dendrites"},{"level":3,"text":"Silicon and other anodes","anchor":"silicon-and-other-anodes"},{"level":3,"text":"Sodium-ion and other post-lithium chemistries","anchor":"sodium-ion-and-other-post-lithium-chemistries"},{"level":3,"text":"Polymer and composite electrolytes","anchor":"polymer-and-composite-electrolytes"},{"level":3,"text":"Computational and machine-learning approaches","anchor":"computational-and-machine-learning-approaches"},{"level":3,"text":"Quantitative benchmarks","anchor":"quantitative-benchmarks"},{"level":2,"text":"Open problems and active debates","anchor":"open-problems-and-active-debates"},{"level":2,"text":"Major programs and players","anchor":"major-programs-and-players"},{"level":2,"text":"Outlook: what to watch (next 12-18 months)","anchor":"outlook-what-to-watch-next-12-18-months"},{"level":2,"text":"Key papers","anchor":"key-papers"},{"level":2,"text":"Glossary","anchor":"glossary"}],"sample_claims":["Li10GeP2S12 (LGPS) was reported in 2011 by its authors with a room-temperature bulk Li-ion conductivity of 12 mS per cm, an early benchmark for sulfide solid electrolytes.","A sulfide superionic conductor was reported by its authors in 2016 with a room-temperature bulk conductivity of 25 mS per cm, the highest bulk value among the sources cited here."],"includes":["markdown","claims","timeline","benchmarks","open_problems","key_papers","glossary","bibliography"],"citation_count":61,"how_to_buy":"GET https://space-kitty.com/api/v1/dossiers/next-gen-batteries with an x402 client ($0.20, USDC on Base Sepolia (testnet))."}
