Nov. 26. 2024. We received an award from Rainforest Innovation to extend our fiber-optics-based battery sensing to cells operating at extreme conditions. Thank you so much Rainforest!
Nov. 18. 2024. We received an award from the NSF EPSCoR program. We will use our self-developed multi-modal microscopy to understand the complex & intertwined chemical/mechanical processes in halide-based solid-state batteries. We sincerely appreciate Prof. Yijin Liu's group at UT Austin in support of the proposal and the kind host. Thank you so much NSF!
Oct. 9. 2024. We received an award from the NASA EPSCoR program. We will build and optimize a fiber-optics-based battery sensing system using the award. This new photonics-based characterization technique will allow the concept of operando spectroscopy to be extended to realistic batteries. Thank you so much NASA!
Oct. 4. 2024. We are very honored to host Prof. Sarbajit Benerjee from Texas A&M visiting our department. Prof. Benerjee gave a very insightful talk on how inorganic chemistry shines on battery materials development.
Jul. 9. 2024. We received an award from NSF CER program. The award will play a more-than-important role in our research program and greatly accelerate our Li-/Na-ion battery material development. Thank you so much NSF!
Jul. 1. 2024. Teaming with Prof. Jim Feng's group at HSC, we received an award from Rainforest Innovation to develop MALDI-MS-based characterization to understand the subtle & complex interfacial chemical processes in batteries. Thank you so much Rainforest!
Jun. 8. 2024. We are glad to be a part of the ROSE program this year and look forward to a fruitful experience.
Apr. 8. 2024. Basirat's paper on "anti-Li3N" cation-disordered niobium tungsten oxide has been published on JACS. Working this structure out is like having an intense class of crystallography. Please take a look. https://pubs.acs.org/doi/abs/10.1021/jacs.3c14275
Apr 1. 2024. Alex's paper on electron localization of cation-disordered rock salts has been published on ACS Energy Letters.
