Grader A: miss

No commercial lithium-air battery existed by 2025; work remains at prototype stage (IIT/Argonne 2025 prototype, CATL 2026 lab claim), with cycle life and electrolyte problems unsolved. Window closed.

Test: D37 Horizons: Li-air battery products buyable by ordinary customers by 2022 for a hit; miss if not available by 2025.

Lithium-air battery (Wikipedia) (2025): Power and cycle life need significant improvement before any market niche; only prototypes reported through 2025-2026.

Grader B: miss

No lithium-air battery was commercially available by 2025 (or 2026); work remains at prototype stage (Argonne 2025 prototype, CATL 2026 announcement).

Test: Li-air battery products could be bought by 2022; partial if limited or by 2023-2025; miss if not available by 2025.

Lithium-air battery (2026): Practical power and cycle life still need improvement before any market niche; only prototypes.
