Teams scaling high-nickel cathodes and Si-rich anodes need repeatable electrochemical evidence before committing to large-format builds. This note summarizes a pragmatic workflow built around Princeton Applied Research / Solartron Analytical instrumentation.
Objectives
Align coin-cell insights with single-layer pouch results; accelerate electrolyte additive screening; use impedance trends during early cycling as a process health signal.
Methods
- CV for first-pass rejection of unstable additive packs.
- EIS at fixed SOC with equivalent-circuit fitting to track interfacial evolution.
- Galvanostatic cycling with rest steps for rate and polarization budgeting.
Outcome
Standardizing acquisition templates let R&D and QC discuss the same interfacial language—reducing cycles spent arguing over setup differences. Yixi bundles channel planning, fixtures, batchable software paths, and training so the workflow survives staff rotations.
Specifications and achievable precision depend on cell geometry and environmental control. Contact Yixi Technology for configuration guidance; final performance is defined by OEM documentation and your internal qualification plan.
