Lithium-ion Battery Quality and Performance Testing with Isothermal Microcalorimetry

Over the past decade, battery research, development, and quality control have adopted in-situ and in-operando isothermal microcalorimetry (IMC) as the leading method to evaluate heat flow during lithium-ion battery cycling. While cycling a cell to failure can take many months, emerging diagnostic tests are able to predict long-term behavior in a matter of weeks.

The Road to U.S. Electric Vehicle Battery Production

Consumer interest and sustainability goals are driving soaring demand for electric vehicles. The U.S. aims for electric vehicle sales to reach 50% of the total market by 2030, yet 99% of the raw and component materials for EV batteries are produced externally.1, 2 Sourcing foreign-made materials and batteries has already created challenges in the industry. Russia’s invasion of Ukraine led to market instability that caused the price of nickel, a key battery material, to skyrocket in March 2022.

Rheology of Paints and Coatings

From shiny cars to streak-free walls, we demand a lot from our coatings and paints. A high-quality paint not only needs dazzling color, but also must offer the right material properties for a smooth application and drying process. Consistency is crucial: too thin and the paint will run and drip; too thick and it will clump and not dry evenly. Spray paints and coatings also need to be applied smoothly without clogging the spray device.

Rheology of Hydrogels

Hydrogels are three-dimensional porous strctures that can absorb large amounts of water. They can be made up of polymers, protein, peptides, colloids, surfactants, or lipids.1 Hydrogels’ ability to uptake large amounts of water is useful for many biological applications, including drug delivery and tissue engineering. Since a hydrogels’ properties change as it absorbs water, scientists must accurately characterize its behavior at different saturation amounts and in varying conditions.
