Study: hydrogen boride nanosheets are a promising hydrogen carrier; 8wt% under ambient conditions

Green Car Congress

The two-dimensional materials derived from magnesium diboride (MgB 2 ) were first reported by researchers in Japan in 2017. Innovative nanosheets made from equal parts of hydrogen and boron have a greater capacity to store and release hydrogen compared with conventional metal-based materials.

UCSD, South 8 team report improved liquefied-gas electrolytes for Li-metal batteries

Green Car Congress

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. cycling efficiency reported in the 2017 Science paper, and an 85% cycling efficiency for lithium metal anodes with a conventional (liquid) electrolyte.

UC Riverside team fabricates nanosilicon anodes for Li-ion batteries from waste glass bottles

Green Car Congress

Silicon anodes can store up to 10 times more energy than conventional graphite anodes, but expansion and shrinkage during charge and discharge make them unstable. Carbon-coated glass derived-silicon (gSi@C) electrodes demonstrated excellent electrochemical performance with a capacity of ~1420 mAh g -1 at C/2 rate after 400 cycles.

AI Is Helping to Stop Animal Poaching and Food Insecurity

Cars That Think

The machine-learning system, dubbed PAWS (Protection Assistant for Wildlife Security), uses data from past patrols to predict where poaching is likely to occur and a game-theory model to help generate randomized, unpredictable patrol routes, according to a 2018 IEEE Spectrum article on the project. www.youtube.com.

New cathode design and understanding of electrolyte delivers greater efficiency in magnesium-ion batteries

Green Car Congress

The new battery stores energy by inserting magnesium monochloride into a host, such as titanium disulfide. Retaining the magnesium-chloride bond doubled the charge the cathode could store. More than that, magnesium ions produced in that way move extremely slowly in the host. That altogether lowers the battery’s efficiency.
