Wildcat Develops New Linear Displacement Measurement Device

San Diego, CA – April 20, 2021 – Wildcat Discovery Technologies, a technology company that uses proprietary high throughput methods to rapidly develop new battery materials, announced today that its engineering team has developed a new Linear Displacement Measurement (LDM) Device that measures small thickness changes in pouch cells during cycling.

Developed in partnership with BMW Group, Wildcat’s LDM capability allows new cell performance feedback as part of projects with its collaboration partners. Measurements of electrode thickness changes can help diagnose failure mechanisms, which can then be used to create improved electrode formulations that mitigate expansion and contraction. Examples of relevant project topics include silicon anode development, lithium metal evaluation, and swelling vs. cycle life correlative studies. The device design is flexible and accommodates a wide range of pouch cell sizes and thicknesses made by Wildcat or its customers. The device is sensitive enough to get useful data with both single and multi-layer cells.

Challenges of Lithium-Ion Battery Material Selection

Substantial improvement in the energy density of rechargeable lithium batteries is required to meet the future needs for electric and plug-in electric vehicles (EV and PHEV). Present day Li-ion technology is based on shuttling lithium between graphitic carbon and inorganic oxides. Blends of cyclic and linear carbonates containing lithium salts and additives dominate the electrolyte technology. However, today’s lithium ion battery electrolytes are not reductively stable on graphite anodes at typical operating potentials.

Digital Battery Element Test improves test coverage of SLI Battery Separator Faults

The performance of a lithium ion battery – energy density, power/rate, durability will depend upon the specific components within as well as the battery design. Today’s state of the art lithium ion batteries used for automotive applications use high nickel containing cathodes, graphite dominant anodes, carbonate-based electrolyte formulations, and ceramic coated separators. However, even within the boundaries of a single component – high nickel cathodes – there are myriad commercial options. Yet, selection of the “best” cathode material for your application is critical to maximize performance and minimize cost. How can we do this better?
