New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

Schematic illustration of 3D porous SiNP/conductive polymer hydrogel composite electrodes. Each SiNP is encapsulated in a conductive polymer surface. A team at Stanford University has developed stable silicon Li-ion battery anodes by incorporating a conducting polymer hydrogel into the Si-based material. Click to enlarge.

Audi unveils e-gas project: synthetic methane from the methanation of green hydrogen; series production of CNG models in 2013 powered by e-gas

Green Car Congress

Starting in 2013, Audi will begin series production of TCNG models whose engines—derived from TFSI units—will be powered by e-gas: synthetic methane produced via the methanation of hydrogen produced by electrolysis using renewable electricity. Audi A3 TCNG for e-gas project. Click to enlarge. The high octane rating of approx.

Georgia Tech prototype triboelectric nanogenerator could extract energy from ocean waves

Green Car Congress

Researchers at Georgia Tech have developed an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy from ocean waves by making use of contact electrification between a patterned plastic nanoarray and water. The tank is filled with deionized water. Or a surface charge density of 4.5

to develop and test a 25 kWh prototype battery system based on nanostructured polymer electrolytes. Prototype pack assembly is to be complete by January 2013, with complete prototype pack performance testing and validation by September 2013. Funds for the 13 projects come from the Public Interest Energy Research (PIER) program.

Hyundai begins rollout of Ioniq Hybrid, PHEV and EV; most efficient non-plug vehicle, most efficient EV in US; powertrain discussion

Green Car Congress

Mike O’Brien, Hyundai vice president of corporate and product planning, noted that the “green car market” in the US has declined a bit—about one hundred thousand units since its high in 2013 with 3.8% kWh Li-ion polymer pack from LG Chem provides the energy storage. This is our first dedicated green vehicle. Top: Rear view (i.e.,

The core of each of these individual cells is a polymer membrane, with a platinum-based catalyst on both sides of the membrane. The protons migrate through the membrane to the cathode, where they react with the oxygen present in air to form water vapor. Meanwhile, outside the stack the electrons supply the electrical power.
