Science Highlight

Quantification of Heterogeneous Degradation in Li-ion BatteriesContacts: Yijin Liu (SSRL), Kejie Zhao (Purdue University), Feng Lin (Virginia Tech), and Yang Yang (BNL)

The development of better rechargeable batteries for consumer electronics and electric vehicles is difficult due to the complex interplay of many chemical, spatial, and temporal factors. Taken together, these factors are called the chemomechanical interplay, which includes chemical degradation, chemical heterogeneity, and mechanical stress that cause the battery to lose functionality over many charging and discharging cycles. A team of researchers has developed a combined methods approach that allows quantification of the processes of chemomechanical interplay over diverse length and time scales.  Read more...


Nominations for SSRL Annual Awards

Recognize outstanding achievements of your colleagues, postdocs, students (or yourself) by submitting nominations for the following awards by the posted deadlines. Send nomination packages for these awards to Cathy Knotts.

William E. and Diane M. Spicer Young Investigator AwardDeadline to submit nominations extended until July 5:  The $1,000 Spicer Young Investigator Award honors the professional and personal contributions that William E. and Diane M. Spicer made to our community. Submit nomination packages including a letter summarizing the scientific contributions of the candidate as well as their CV and publications (supporting letters also encouraged). Award Site

Melvin P. Klein Scientific Development Award Submit nominations by August 1:  This $1,000 award honoring Mel Klein's many contributions recognizes research accomplishments of undergraduate/graduate students or postdoctoral fellows within three years of receiving their Ph.D. This award provides peer recognition and helps to promote dissemination of results based on work performed at SSRL. The nomination package should include the candidate’s CV, letters of recommendation from the advisor and colleagues, as well as an abstract written by the candidate describing the SSRL related experiments, scientific results, and plans to present the findings. Award Site

Farrel W. Lytle Award – Submit nominations by August 5:  The $1,000 Lytle Award was established to promote technical or scientific accomplishments in synchrotron radiation-based science and to foster collaboration and efficient use of beam time at SSRL. SSRL users and staff are eligible to be nominated for the Lytle Award. Letters of nominations should include a summary of the individual's contributions and why they should be recognized through this award. Supporting letters are welcome.

These awards will be presented at the SSRL/LCLS Annual Users’ Meeting, and the recipients of the Klein and Spicer awards will be asked to present their research during the plenary session of the Users' Meeting on September 26.
