1. The Importance of Electrochemical Performance of Solid-state Electrolyte

Driven by the rapid development of the lithium-ion battery (LIB) industry, improving the energy density and safety of the battery is an important research direction of for the LIB researchers. All-solid state battery is considered to be the most promising secondary battery with high safety and high specific energy in the future. Solid electrolyte (SE) is the most important core component, and the most important performance indicators used to judge the performance of solid electrolyte are ionic conductivity,Li-metal interface stability and full cell performance. On the one hand, the density, roughness and integrity of the pressed solid electrolyte sheet determine the conductivity of the solid electrolyte and the cycle performance of the full cell. On the other hand, the accuracy of the test results can only be guaranteed by the stable and uniform stress application and the accurate thickness measurement during the experiments. Therefore, the production and testing system that can exert stable and standardized pressure plays a key role in the development of solid electrolyte and lithium metal battery.

2. Limitations of Conventional Tablet Fabrication & Testing

  • Pellet Pressing Process: Ceramic pellets are prone to fracturing or edge chipping, which disrupts experimental workflows and lowers R&D efficiency.

  • Testing Process: Simple fixture clamping causes uneven stress distribution and offers limited force magnitude, resulting in poor measurement consistency and low repeatability.

  • Condition Exploration: Inability to deliver uniform, stable, or dynamically controlled pressure required for solid electrolyte pellet preparation and testing parameter exploration.

  • Measurement Mode: Restricted to constant unquantified pressure, narrow force application range, and unstable load maintenance during testing.

Solid electrolyte testing comparison: ceramic pellet defects (depression, edge falling, fragmentation) caused by traditional tablet press and manual test fixtures.
