Quintus Technologies has introduced a small-footprint isostatic battery press for the laboratory environment. The new system, the MIB 120, has been specifically designed to meet the needs of the research community, with its space-saving profile and minimal need for additional infrastructure. The new press has been engineered to deliver results consistent with larger Quintus battery presses, an invaluable capability for universities and institutes engaged in basic research, feasibility, and prototyping studies of Isostatic Battery Pressing.

“We listened to the cell design engineers and developed the MIB 120 press accordingly,” said Peter Henning, Director of Marketing and Sales at Quintus Technologies. “Now, the parameters chosen for pressure and temperature are consistent throughout the entire Quintus battery press line, from the new small lab model to our large-scale mass production machines. This enables a smooth  transition for scaling up cell or pouch sizes without compromising on process or quality.”

Compared with other compressing technologies, isostatic pressing stands out as one of the most effective methods to address challenges in solid-state battery development. According to Henning, studies have shown that isostatic pressure is the only way to close the porosity in coated composite layers inside solid-state batteries effectively to a degree that creates peak electrochemical performance. This allows for uniform compression of small and large multilayer cells – preserving the internal layered structure of components without creating local defects or inhomogeneities.

The multitude of orders Quintus has received from both start-up and OEM-level customers confirms that the company’s isostatic battery presses are playing a key role in the research, development, and mass production of solid-state batteries.

“Thermal runaways in lithium-ion batteries are a continuing discussion topic with respect to personal safety in the automotive and electronics industry,” said Jan Söderström, CEO and President of Quintus Technologies. “Unlike conventional lithium-ion cells, solid-state batteries do not contain a liquid electrolyte, making them inherently safer whilst offering the added benefits of improved energy density, shorter charging times, and a smaller carbon footprint.”

The MIB 120 can reach pressures of 600 MPa (87,022 psi) and temperatures of 140°C (284°F), which are fully scalable parameters for industrial presses from Quintus Technologies. The press is designed to have a very high-temperature uniformity, which guarantees a high reproducibility of cells, under conditions that can be transferred to mass production once concepts have been proven.

The research model includes a heated pressure vessel, pressurization system, heated fluid reservoir, and all instrumentation controls. The self-contained system is delivered ready for connection to air and electricity.

“As the leader in the production of high-pressure equipment for more than 70 years, we are focused on the development of long-term customer relationships,” said Söderström. “Offerings such as access to global research partners and trials in our Customer Application Centers add significant value, strengthening our partnerships with solid-state battery companies throughout the supply chain. These partnerships also support Quintus’s commitment to using our high-pressure technology to advance sustainability.”
