The Washington University in St. Louis lab of Peng Bai, assistant professor in the Department of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering, has developed a stable sodium ion battery that is highly efficient, will be less expensive to make and is significantly smaller than a traditional lithium ion battery due to the elimination of a once-necessary feature.

Washington University in St. Louis is committed to meeting the safety needs of its entire community. Today, the university announced plans for how it will implement recommendations made recently by its Public Safety Committee.
The committee issued its report to university leadership in February. The group, composed of students, faculty, alumni and staff, was convened to examine public safety and policing on the Danforth Campus and in nearby neighborhoods. It thoroughly examined the current landscape of services and conducted an extensive survey to get feedback from the Danforth Campus community before preparing and presenting its report, which included several key recommendations that the university plans to implement in the near future.
