U Maryland and US Army Research Lab furthering “water-in-salt” electrolyte Li-ion battery; targeting EV use

Green Car Congress

This water-in-salt electrolyte lithium battery recently achieved an energy density of 200 Wh/kg, said Dr. Chunsheng Wang at UMD, adding that the DOE had sought 150 Wh/kg, or double that of a traditional aqueous Li-ion battery. “ Earlier post.) The UMD-ARL team won the Invention of Year of UMD in 2016 for the technology. Click to enlarge.

UMD/USARL team develops “water-in-salt” electrolyte enabling high-voltage aqueous Li-ion chemistries

Green Car Congress

A common practice to suppress hydrogen evolution in aqueous electrochemistry is to adjust the alkalinity, so that the water reduction potential shifts downward to allow the use of anode materials otherwise prohibited under neutral or acidic conditions. What’s most important about our work is the breakthrough made at the fundamental level.

Renault Trucks’ Optifuel Lab 2 lab vehicle integrates technologies for more efficient big rigs; road test results coming in 2015

Green Car Congress

These figures will be announced during the first quarter of 2015. The idea is to take as little energy as possible from the internal combustion engine. We therefore electrically powered several of the vehicle’s auxiliary items of equipment such as the air-conditioning, water pump, fuel pump and the steering pump.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap.

IEEE Society Restores Electricity To a Nepali School

Cars That Think

Until recently, the residents of Melamchi, Nepal, cooked meals and heated water for bathing over a wood-burning stove. Restoring electricity after an earthquake The idea for the project came from a chance encounter in a shopping center. A 200-liter solar water heater was installed in the school’s dormitory.

Autonomous Boats Seem More Solvable Than Autonomous Cars

Cars That Think

Where autonomous vehicles have had the most success is in environments with a lot of predictability and structure, which is why I really like the idea of autonomous urban boats designed for cities with canals. The public demo in Amsterdam kicks off tomorrow, and by the end of 2021, the hope is to have two boats in the water.

easyJet to trial electric taxi system in aircraft; H2 fuel cells, batteries and wheel motors

Green Car Congress

The only waste product is fresh clean water which could be used to refill the aircraft’s water system throughout the flight. The system would therefore reduce, if not remove altogether, the need for tugs to maneuver aircraft in and out of stands, delivering more efficient turnaround times and increased on-time performance.
