CM-BAT-103

CM-BAT-103 Murray-law electrode [E2] (003 + 006 + 013)

CURRENT IDEAS: CM-BAT-103.

• R01b: mass accounting caps thick-electrode gain at ~+10 % cell / ~+8 % pack. Corrects my +15-25 % claim for CM-BAT-103. Status: [challenged] — stays open only if a Newman-model run shows ≥80 % capacity at 300 µm, 1C, tortuosity ~1.2.

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

• 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.
