Low-cost N-doped interlayer derived from loofah sponge enables high-performance Li-S, Li-Se and LiI2 batteries

Green Car Congress

Researchers from Griffith University in Australia and Peking University in China have synthesized low-cost, hierarchically porous, and nitrogen-doped loofah sponge carbon (N-LSC) derived from the loofah sponge via a simple calcining process and applied it as a multifunctional blocking layer for Li–S, Li–Se, and Li–I 2 batteries.

Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. Recently, there has been much interest in the development of electronic and energy storage devices using paper and textile components.

Heliostat Consortium announces 7 projects to receive combined $3.5M in funding; DOE launches Heliostat Prize

Green Car Congress

Heliostats are mirrors that track the sun in order to reflect highly concentrated sunlight to a receiver, where it can be stored as heat for long-duration energy storage and converted into electricity. Low-cost heliostats offer significant renewable energy potential.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.
