UMD, Army Researchers design new electrolyte enabling high energy density rechargeable Mg and Ca batteries

Green Car Congress

Rechargeable magnesium and calcium metal batteries (RMBs and RCBs) are promising alternatives to lithium-ion batteries because of the high crustal abundance and capacity of magnesium and calcium. This work provides a versatile electrolyte design strategy for divalent metal batteries. —Hou et al.

U Maryland team devises new method to stabilize high-capacity Si anodes for Li-ion batteries: interfacial oxygen

Green Car Congress

Researchers at the University of Maryland have improved the cycle life of silicon/carbon matrix-composite electrodes by 300%, even at mass loadings, solely by the chemical tailoring of the interface between the silicon and the carbon with atomic oxygen. 10 times that of graphite anodes used in lithium ion batteries. Batteries'

NREL-led team overcomes major technical obstacle in Mg-metal batteries by developing artificial solid-electrolyte interphase

Green Car Congress

Magnesium offers a number of advantages over lithium for rechargeable batteries: it is safer and earth-abundant, and doubles the total charge per ion, delivering larger theoretical volumetric capacity compared with a typical lithium-ion battery. Further, in Mg batteries (MB) the anode is energy-dense Mg metal (~?3,830

ARPA-E awarding $36M to 22 projects in RANGE program for transformative EV storage

Green Car Congress

ARPA-E’s RANGE program seeks to improve EV driving range and reduce vehicle costs by re-envisioning the total EV battery system, rather than working to increase the energy density of individual battery cells. For example, the University of California, San Diego will receive approximately $3.5 University of Houston.
