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. See, Joseph P.

New high-activity, low-cost nickel-based catalyst for fuel cells exhibits performance similar to Pt; hydroxide exchange membrane fuel cells

Green Car Congress

Owing to its high activity and low cost, the catalyst shows significant potential for use in low-cost, high-performance fuel cells, the team suggested. This new hydroxide exchange membrane fuel cell can offer high performance at an unprecedented low cost. —Zhuang et al. —Zhuang et al.

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 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.

Why a Fiat 500e driver got a Honda Clarity Fuel Cell as his next green car: low cost

Green Car Reports

Part of his interest in the Fiat, he admitted, came from an article about a group of race-car enthusiasts who. When marketing executive Chris Baccus leased a 2015 Fiat 500e three years ago, he intended to keep his 2007 BMW 335i as a "fun car," and use the electric Fiat just for commuting. Within six months, he'd sold the BMW altogether.
