8/23/2023 0 Comments Solid state battery vs lithium ion![]() In fiscal year 2021, the office reported 159 deals finalized with 236 technologies signed, 394 disclosures received and 187 issued U.S. Services provided by this office support the economic development initiatives of Purdue University and benefit the university’s academic activities through commercializing, licensing and protecting Purdue intellectual property. The Purdue Research Foundation Office of Technology Commercialization operates one of the most comprehensive technology transfer programs among leading research universities in the U.S. Ībout Purdue Research Foundation Office of Technology Commercialization See how Purdue never stops in the persistent pursuit of the next giant leap at. Committed to affordability and accessibility, Purdue has frozen tuition and most fees at 2012-13 levels, enabling more students than ever to graduate debt-free. Committed to hands-on and online, real-world learning, Purdue offers a transformative education to all. News & World Report, Purdue delivers world-changing research and out-of-this-world discovery. Ranked in each of the last five years as one of the 10 Most Innovative universities in the United States by U.S. Purdue University is a top public research institution developing practical solutions to today’s toughest challenges. Pol’s work on the new composite material has been funded by the Office of Naval Research and Purdue Research Foundation Office of Technology Commercialization’s Trask Innovation Fund. Industry partners seeking to further develop this innovation should contact William Buchanan, about reference numbers 20. He disclosed the innovation to the Purdue Research Foundation Office of Technology Commercialization, which has applied for a patent on the intellectual property. Pol’s research has been published in the November 2020 and July 2021 issues of the peer-reviewed Chemical Engineering Journal. Pol and his team have continued their research to make the material even safer via electrolyte composite optimization, battery overcharging, and nail penetration and thermal abuse testing. “We have further developed advanced electrolytes with fire-retardant molecules as a quasi-solid-state battery, enhancing the lithium-ion battery safety.” And low-energy-density batteries can cause quick energy depletion and short operating times of devices, considering the limited space for a battery in electronics or electric vehicles. “Their ionic conductivity is limited to low temperatures, which can reduce energy efficiency and lifetime. “They have poor thermal stability, which can cause battery thermal runaway and lead to catastrophic firing,” Pol said. Pol said traditional SPE materials have other drawbacks. It exhibits stability to cell damage, leading to a huge increase in safety.It shows excellent thermal stability up to around 330 degrees Celsius.It has an optimized ionic conductivity of around 2.4*10^4 microsiemens.It has a wide voltage window of around 4.8 volts.Pol’s new, patent-pending composite material improves upon traditional SPE materials in several ways: One of their most dramatic drawbacks is that they often explode when damaged.Ī team led by Vilas Pol, a Purdue professor in the Davidson School of Chemical Engineering, has developed a new composite material that is safer to use in those batteries than traditional solid polymer electrolyte, or SPE, technologies. High-voltage, solid-state lithium-ion batteries are the go-to power source for high-end technologies like electric and hybrid vehicles, wearable devices, pacemakers, radio-frequency identification systems and more. – Purdue University engineers are making one of the most-used power sources safer and more efficient. Batteries made with the new composites remain operational when damaged instead of exploding like traditional batteries
