Abstract
En 中文
• Controlled benchmarking of half-cell fitting methods using known degradation modes. • Fabricated LFP/Gr cells enable ground-truth validation of loss estimates. • Identifiability of degradation modes shown to depend on optimization choices. • Benchmark extended to ̃4-year aging data from implantable-grade LCO/Gr cells.
