Active Wake record · Pilot
Solid-state battery dendrite deflection
A laboratory technique redirected a destructive failure instead of eliminating it. Replication and scale will decide whether that geometry travels beyond one cell architecture.
Current reading
Where the record stands
The peer-reviewed laboratory result is real within its tested system, but manufacturability, pack-level safety, lifetime, and independent replication remain open.

- Review for independent replication, larger-format cells, manufacturing integration, or end-to-end safety and lifetime measurements.
Point zero
What was known when we noticed it
Researchers reported that biaxial compression redirected lithium dendrites perpendicular to the electric field in a garnet solid electrolyte, allowing many internal dendrites to form without immediately short-circuiting the cell.
Supported at the time
- The team used a heated shape-memory-alloy ring to apply compression.
- Imaging supported lithium initiation at pores and grain-boundary junctions.
- The reported cells continued for thousands of cycles while horizontal dendrites accumulated.
Still uncertain
- The strategy was demonstrated in a laboratory system using one garnet electrolyte, not a production battery architecture.
- Manufacturability, pack-level behavior, energy cost, safety, and independent replication remained unknown.

Admitted to The Wake pilot
Admitted because it provides a clean laboratory baseline against which replication and practical scale-up can be compared.
Lifecycle: EmergingEvidence: PreliminaryAttention: Unmeasured
Unresolved
Open questions
- Will an independent group reproduce the deflection mechanism?
- Can the applied stress be integrated into practical cell manufacturing and cycling conditions?
- Does the strategy improve safety and lifetime at commercially relevant scale?
Future evidence
What would move the record
Independent replication or critique
Another research group tests dendrite deflection under biaxial stress.
UnknownLarger-format or manufacturable cell demonstration
A study reports practical architecture, scale, lifetime, and full-system tradeoffs.
UnknownProvenance
Source trail
A lineage identifies sources that ultimately descend from the same paper, announcement, interview, wire report, or other evidentiary ancestor. Repetition within one lineage is not counted as independent corroboration.
