Increasing Ionic Conductivity of Poly(ethylene oxide) by Reaction with Metallic Li

Autor: Pei Liu, Michael J. Counihan, Yisi Zhu, Justin G. Connell, Daniel Sharon, Shrayesh N. Patel, Paul C. Redfern, Peter Zapol, Nenad M. Markovic, Paul F. Nealey, Larry A. Curtiss, Sanja Tepavcevic

Publikováno v: Advanced Energy & Sustainability Research, Vol 3, Iss 1, Pp n/a-n/a (2022)

Poly(ethylene oxide) (PEO) was the first lithium‐ion conducting polymer developed 50 years ago and is still the most popular electrolyte matrix for solid‐state lithium metal batteries. While many studies focus on increasing PEO ionic conductivity

Photo-accelerated fast charging of lithium-ion batteries

Autor: Anna Lee, Márton Vörös, Wesley M. Dose, Jens Niklas, Oleg Poluektov, Richard D. Schaller, Hakim Iddir, Victor A. Maroni, Eungje Lee, Brian Ingram, Larry A. Curtiss, Christopher S. Johnson

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)

Here the authors show that illumination of a lithium manganese oxide cathode can induce efficient charge-separation and electron transfer processes, thus giving rise to a new type of fast lithium-ion battery charging.

A chiral molecular propeller designed for unidirectional rotations on a surface

Autor: Yuan Zhang, Jan Patrick Calupitan, Tomas Rojas, Ryan Tumbleson, Guillaume Erbland, Claire Kammerer, Tolulope Michael Ajayi, Shaoze Wang, Larry A. Curtiss, Anh T. Ngo, Sergio E. Ulloa, Gwénaël Rapenne, Saw Wai Hla

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)

Controlling the rotation direction of individual molecular machines requires precise design and manipulation. Here, the authors describe a surface-adsorbed molecular propeller that, upon excitation with a scanning tunneling microscope tip, can rotate

Deactivation of redox mediators in lithium-oxygen batteries by singlet oxygen

Autor: Won-Jin Kwak, Hun Kim, Yann K. Petit, Christian Leypold, Trung Thien Nguyen, Nika Mahne, Paul Redfern, Larry A. Curtiss, Hun-Gi Jung, Sergey M. Borisov, Stefan A. Freunberger, Yang-Kook Sun

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Redox mediators can enhance redox reactions in Li-O2 batteries; however, their gradual degradation remains unclear. Here the authors show that organic redox mediators are decomposed by singlet oxygen formed during cycling, indicating a strategy for t

Subnanometer cobalt oxide clusters as selective low temperature oxidative dehydrogenation catalysts

Autor: Sungsik Lee, Avik Halder, Glen A. Ferguson, Sönke Seifert, Randall E. Winans, Detre Teschner, Robert Schlögl, Vasiliki Papaefthimiou, Jeffrey Greeley, Larry A. Curtiss, Stefan Vajda

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)

Current oxidative dehydrogenation processes are based on petroleum cracking that is indirect, environmentally unfriendly, and energy intensive. Here, the authors discover that subnanometer sized cobalt oxide clusters are active for oxidative dehydrog
