This is one of Roadmap's ready-made topic templates — a starting point for tracking something over time without writing a tracking brief from scratch.
Roadmap is an AI-assisted document editor: markdown with a live preview, a discussion panel where you can ask the AI about a specific section and apply its suggested edit straight to the text (you choose exactly what goes into each request's context), version history with restore, and export in multiple formats. Its "AI Update" button, on any document, searches the web for what has changed since you last checked and updates the document — with dates and sources — only when it finds something genuinely new.
To use this template: click "Open in Editor" above to copy it into your own documents, then press "AI Update" whenever you want to check for news. Browse the sidebar for more topics and categories.
Renewable Energy: Solid-State Batteries
Brief
Tracking breakthroughs in solid-state battery technology: claimed efficiency/capacity figures, specific facilities going into operation, major grants and investments. Not needed: press releases without concrete technical numbers.
Description
Genuine solid-state batteries remain economically uncompetitive at scale, but the gap between lab announcements and real commercial deployment has narrowed meaningfully, with China setting the pace on manufacturing scale-up.
First Commercial Deployment
Verge Motorcycles became the first production vehicle to feature solid-state battery technology, using Donut Lab's all-solid-state cells on the road starting Q1 2026 — charging in under 10 minutes for up to 60 km of range per minute of charging.
China's Aggressive Push
China's solid-state battery standard launched in July 2026, alongside multiple manufacturers beginning pilot production. Greater Bay (backed by GAC) rolled out all-solid-state A-sample cells reaching a single-cell energy density of 260–500 Wh/kg — well above traditional liquid lithium-ion — targeting gigawatt-hour-level mass production within the year.
Industry Reality Check
Broader industry consensus remains cautious: true all-solid-state batteries face a 3x–5x production cost premium and remain confined to pilot-scale testing, while semi-solid-state (solid-liquid hybrid) batteries are considered the only technology realistically scalable for vehicles in 2026. High-volume, cost-competitive all-solid-state production is more realistically expected in the early 2030s.
