Lineage (every mention in the registry, in order)

idea.md:115

Status: CM-BAT-103 [negative-result] closed as density idea. Fork CM-BAT-103a (fast-charge acceptance) [hypothesis] — charge sweep pending.

idea.md:119

Status: CM-BAT-103a [negative-result]. Residual defensible claim: hierarchical porosity = one step of charge rate (C/3→C/2) at 2× thickness, ~+8 % Wh/kg. Reopen only with graded porosity or kinetic plating submodel.

CM-BAT-103 — [negative-result] closed by CM-BAT-R02. Fork CM-BAT-103a — [negative-result] closed by CM-BAT-R03. Residual: +8 % Wh/kg at 2× thickness with C/2 charging. Reopened as CM-BAT-103b (specie) — R05: weakly supported at 300 cycles (Δretention 0.6 pt, plating +26 %, SEI equal). LITERATURE CHECK 2026-09-27: 103b already established experimentally (Cai 2025 Small Methods τ 3.82→1.67, −91 % plated Li @600 cyc; Chen 2020 JPS 91 %/86 % @600 cyc 4C/6C; KIT Appl. Energy 2021 SOH 85 vs 90–92 % @250 cyc C/2 with post-mortem). 103b → [known, E3]. Fork CM-BAT-103c — [open] the design trade-off curve: at fixed lifetime target, extra thickness (Wh/kg) bought per unit τ reduction, matched loading, C/3–1C, τ up to 4, SEI-on-cracks enabled.
