Limits RegistryPUBLIC RECORD
Limits RegistryAmprius Technologies' silicon-anode lithium-ion cell was independently verified at 500 Wh/kg by Mobile Power Solutions in 2023, making it the first commercially available cell verified at that level. It targets niche high-value markets (drones, aerospace, defense) rather than mainstream EVs, which typically run 250-300 Wh/kg.
The question, scope, and sources behind this Registry record.
Amprius Technologies' silicon-anode lithium-ion cell was independently verified at 500 Wh/kg by Mobile Power Solutions in 2023, making it the first commercially available cell verified at that level. It targets niche high-value markets (drones, aerospace, defense) rather than mainstream EVs, which typically run 250-300 Wh/kg.
The highest specific energy (Wh/kg) independently verified for a battery cell that a company sells commercially, as opposed to a lab-only research prototype.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
