Lithium Batteries: Current State and Beyond

Rechargeable lithium-ion batteries were first commercialized by Sony in early 90’s. The high cost of cobalt and relatively low specific capacity of LiCoO2 (140Ah/kg) have been major obstacles against the application of these batteries in transportation where the battery energy density should significantly increase to meet the goals for plug-in hybrid vehicles (PHEVs), and essentially for electric vehicles (EVs). Also, despite the abundance of iron and manganese, olivine LiFePO4 and spinel LiMn2O4 will not likely be adequate candidates since neither of them can provide enough gravimetric and volumetric energy densities for transportation applications. Therefore, research groups have been under the challenge of inventing and developing new advanced positive electrode materials whose main characteristics is to store more and more electricity per mass and volume. Of these materials, advanced composite materials were found to deliver a high reversible capacity (250Ah/kg) while being structurally and electrochemically stable upon charge and discharge. These thermally stable materials are considered as potential candidates to surmount the energy density shortfall of current lithium ion batteries. The journey for materials design and discovery will be unveiled in the light of the most recent developments in lithium-ion batteries. Also, the implementation of the very challenging lithiumsulfur and lithium-air batteries will be discussed.

Research Experience for Teachers (RET)

Michigan Tech is again hosting seven middle and high school teachers from Michigan and Wisconsin in a six-week Research Experience for Teachers (RET), a program funded by the National Science Foundation, which ends this week.
The teachers presented posters on their research experiences, as well as the development of classroom/laboratory units, Friday, Aug. 17, in Memorial Union Alumni Lounge B.

Mobile Lab is on the road

The Michigan Tech Mobile Lab is on the road to southeast Michigan today through Tuesday, Aug. 14.

Lab director Jeremy Worm led a team of graduate and undergraduate students and members of the Michigan Tech Chapter of the National Society of Black Engineers. They will meet with engineers and training coordinators from two companies, Mahle Powertrain and Detroit, to showcase the Mobile Lab’s offering of hands-on short courses.

As well, the lab will provide fun-filled STEM activities for inner city youth at the Parental Boot Camp being organized by Heroes Alliance of Detroit.
