Researchers developing DC micro smart grid for charging EV fleets; Li-ion, redox flow batteries and renewables

Green Car Congress

Up to 30 electric vehicles at a time can recharge in Fraunhofer IAO’s parking garage. The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. In addition, a lithium-ion battery storage unit will be added to the basement.

Univ. of Missouri team progressing with convection battery; enabling rechargeable lithium-metal batteries

Green Car Congress

The Li / Support is the electrode made possible with the convection battery technology. Researchers at the University of Missouri led by Prof. The technology allows lithium-metal batteries to be recharged without the dendrite failure (short circuit) that has prevented rechargeable lithium-metal batteries from being commercially viable.

Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance. —Dubarry et al.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. In addition, material sustainability is also a critical factor when considering the total economic and environmental benefits for grid-scale energy storage applications.

UC Riverside team develops new coating strategy for Li-metal anodes to prevent dendrite formation

Green Car Congress

A team of researchers at the University of California, Riverside has developed an approach to addressing the vexing problem of dendrite formation that hobbles the use of high energy density lithium-metal anodes in advanced recyclable batteries. The earliest non-rechargeable Li batteries using Li metal as anode appeared in the 1970s.
