Application Scope

This press is an essential tool for compressing powder materials into pellets or sheets in laboratory R&D and production facilities.

Core Applications in battery materials R&D

In battery research, this press is primarily used to compress mixed powders—including cathode/anode active materials, conductive agents, and binders—into dense electrode sheets or pellets. This is a critical step in developing high-performance batteries such as lithium-ion, solid-state, and sodium-ion batteries.

Key roles include:

Improving Energy Density: High-pressure compaction significantly reduces void spaces between powder particles, allowing more active material to be packed into a given volume, thereby increasing energy density.

Establishing Ion Transport Pathways: Compaction creates tight, continuous physical contact between solid electrolyte and electrode particles, providing smooth pathways for ion conduction—especially essential for solid-state battery operation.

Reducing Interfacial Resistance: Intimate particle contact lowers the interfacial resistance between different materials, enabling more efficient energy conversion within the cell.

Fabricating Multilayer Structures: The press can be used to layer and compress different electrode and electrolyte layers into integrated battery units, such as bilayer or multilayer pellets.

Operational & Selection Tips

To achieve optimal experimental results, consider the following points:

1. Select Appropriate Pressure – Different battery material systems require different compaction pressures. For example, some sulfide solid electrolytes may need 370–400 MPa to reach optimal performance. This 12T press can provide up to 12 tons; users must calculate the actual applied pressure in MPa based on the sample area to ensure it meets experimental requirements.

Quick Pressure Estimation*: Actual pressure (MPa) ≈ Force (tons) × 98.1 / Sample area (cm²). For instance, applying 12 tons on a 1 cm diameter pellet generates much higher pressure than on a 3 cm diameter pellet.

2. Ensure Uniform Pressure Distribution – Uniform compaction is critical. Non-uniform density can cause uneven current distribution within the battery, compromising the reliability of experimental data.

3. Use Compatible Dies – By exchanging dies of different sizes and shapes, the press can produce various sample forms such as pellets, sheets, or rods to suit different analytical tests like XRF or SEM, or for battery assembly procedures.
