Battery Processing Systems

All-solid-state battery (ASSB) technology has been under development for years, offering significant improvements in safety, charging times, and energy density. Quintus has been at the forefront of this innovation, providing advanced isostatic pressing solutions to support all-solid-state battery production from the lab to full-scale manufacturing.

Benefits of Warm Isostatic Pressing for Battery Processing

Several challenges have hindered the commercialization of all-solid-state batteries (ASSBs), including residual porosity in components, inadequate particle contact, and changes in cell volume during charging and discharging. However, Warm Isostatic Pressing (WIP) has emerged as a critical solution to address these issues.

Reduced Internal Resistance

WIP lowers internal resistance by reducing porosity and improving particle contact, especially in sulfide-based ASSBs, where it decreases ionic grain-boundary resistance and overall porosity.

Increased Cycle Life

By enhancing material density and structural integrity, WIP increases the cycle life of ASSBs, ensuring better long-term performance and stability.

Enhanced Coulomb Efficiency

WIP optimizes particle density and homogeneity, leading to better charge-discharge efficiency and higher Coulomb efficiency, while also enabling uniform pressure sintering even for multilayer cells.

Flexibility in Cell Sizes and Geometries

WIP can process cells of various sizes and shapes, applying uniform pressure and temperature, overcoming challenges faced by other methods like uniaxial pressing.

Testimonials

“Using solid ceramics instead of liquid electrolytes in batteries is expected to increase safety, as well as energy density and charging capabilities. However, work with new layers of electrolyte materials indicates that the common uniaxial methods such as calendaring, or hot pressing, lead to insufficient electrode density and lower electrochemical performance. Therefore, warm isostatic pressing is labeled a key technology in creating sufficient particle-to-particle contact.

Additionally, the equipment (MIB 120) is manufactured to the latest ASME pressure vessel code for high pressure operation, ensuring the operators’ safety, which is paramount in my research group. With this equipment-supplier/academic-research strategic partnership, we will be able to achieve greater advancements for all-solid-state batteries and move towards commercialization at a faster pace.”

FAQ

While we are open to different approaches and chemistries, the current focus is on sulfide solid electrolyte cells and the pouch cell format as these appear to have highest industrialization momentum.

Concepts such as “anode-free” designs, lithium metal anodes and dry-coated electrodes are very interesting for us on a production level of testing.

Most commonly the warm isostatic processing step is located after pouching and sealing of the cell, enabling the press to be located outside of dry room conditions.

Although the battery industry is focused on pressing complete multilayer cells, it is also possible to press electrodes and solid electrolytes by themselves before stacking.

The cost of warm isostatic cell processing in GWh scale production is projected to be in the lower EUR cent area per kWh.

Given the horizontal press design enabling one-directional material flow, the available range of large vessel volumes and existing automation solutions of our integration partners, the throughput of a high-volume production line will not be bottlenecked by the Warm Isostatic Pressing (WIP) process if sized correctly.
