UCSD team suggests building more fast-charging stations based on study of pandemic impact on EV charging

Green Car Congress

A team of engineers at the University of California San Diego (UCSD) recommends expanding fast-charging stations for electric vehicles as campuses and businesses start planning for a post-pandemic world. As expected, charging declined significantly once most campus operations became remote.

UCSD team develops new disordered rock salt anode for fast-charging, safer lithium-ion batteries

Green Car Congress

Researchers at UC San Diego, with their colleagues at other institutions, have developed a new anode material that enables lithium-ion batteries to be safely recharged within minutes for thousands of cycles. volts versus a Li/Li + reference electrode. other intercalation anode candidates (Li 3 VO 4 and LiV 0.5 —Liu et al.

INL, UCSD researchers find slow, low-energy charging of Li batteries creates glassy lithium; high-performance Li-metal batteries

Green Car Congress

Scientists from Idaho National Laboratory and the University of California San Diego have shown that slow, low-energy charging causes lithium atoms to deposit on electrodes in a disorganized way that improves charging behavior. Lithium metal is a preferred anode for high-energy rechargeable batteries.

Volvo LIGHTS team helps facilitate authorization for public MDHD EV charging stations in California

Green Car Congress

Prior to this modification, California utilities were guided by a California Public Utilities Commission (CPUC) decision established in 2010 that exempted light-duty vehicle charging station providers from being regulated as a utility but did not explicitly exempt medium- and heavy-duty charging station providers.

Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market. Shirley Meng, a nanoengineering professor at UC San Diego. The answer has to do with how lithium deposits on the anode when the cell is charging. So there is another important aspect that is being overlooked.
