Berkeley Lab scientists generate low-cost, hybrid thermoelectric materials

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have constructed a low-cost, nanoscale composite hybrid thermoelectric material by wrapping a polymer that conducts electricity around a nanorod of tellurium—a metal coupled with cadmium in today’s most cost-effective solar cells.

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. Water splitting is a challenging reaction. An open access paper on their study is published in the journal Nature Communications. —co-author Jeff Brinker, Sandia Fellow and University of New Mexico professor.

New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

The battery, which can be low cost and reliable in terms of safety, provides another chemistry for post Li-ion batteries, they suggest, and with higher practical energy densities than Li-air systems for supporting applications including electric vehicles and large-scale grid energy storage. Its average discharge voltage is about 4.0

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

New low-cost bio-inspired nanostructured MoS2 catalyst performs almost as efficiently as Pt for hydrogen production

Green Car Congress

The team mixed molybdenum disulfide with water and used the printing process to expel micron-size droplets into an enclosed area about 2 feet high. Researchers from King Abdullah University of Science and Technology, Lawrence Berkeley National Laboratory and Yale University also contributed to the article. —Chen et al.
