Battery Processing Systems

Solid-state battery (SSB) 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 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 solid-state batteries (SSBs), 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 SSBs, 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 SSBs, 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

We are open for different approaches, but focusing more on the pouch cell format. Concepts featuring a lithium metal anode or in situ lithium metal anode are very interesting for us on a production level of testing. We are testing solid-state electrolyte systems featuring sulfides, oxides and composites on a daily basis in our application centers in Sweden and the US.

That depends on the cells design for an in-situ (or anode-free) lithium metal anode concept Quintus proposes a densification step of whole pouch cells. This position would fit the isostatic press after stacking and pouching.

The upfront investment seems high, but is rather low compared to other machinery used in today’s battery manufacturing. Calculations with a realistic cost-model we established, put isostatic pressing in the lower cent area per KWh. The calculation model fits different parameters, the ones that show a high impact are pouch dimensions and vessel size, which can be adapted to customers preferences.

The batch characteristic is an important topic for discussion. Our simulation shows that automation of the loading, unloading and densification won’t be a challenge for the implementation of isostatic pressing in the overall process. Additionally, the speed of stacking/winding is limiting the process speed before densification.
