Solid-state battery coin cell mold-Constant pressure model with sping

This mold is designed for in‑situ pressure testing of battery cells. It features a constant‑pressure mechanism and universal indenters compatible with both positive and negative electrodes. The compact, robust construction ensures reliable sealing and easy operation, making it ideal for materials research, electrochemical analysis, and high‑pressure performance evaluation.

Key Features

1. Five colour‑coded springs
   Different colours indicate different load ratings, allowing quick visual identification and matching to experimental requirements.

2. High‑precision indenters

   • Mirror‑polished finish; the same indenter works for both positive and negative electrodes – simply check the polarity mark on the cavity.

   • Made of newly formulated steel with an exclusive heat‑treatment process, achieving a hardness of HRC 55–58 while offering excellent corrosion resistance.

   • The current collector is also mirror‑polished for optimal contact.

3. Hexagonal locking caps (top and bottom)

   • Designed for use with a standard wrench.

   • Effectively solves the problem of difficult unscrewing after charge/discharge cycles, prevents rolling, and improves sealing performance.

4. Protective design

   • PEEK protective sleeve combined with a zirconia ceramic liner ensures high pressure resistance, chemical inertness, and long‑term stability.
