New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

Researchers in Europe, with colleagues from Samsung R&D Institute in Japan, have developed a highly stable Fe 3 O 4 /C composite for use as a conversion electrode in all-solid-state Li-ion batteries. In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism.

Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. A paper on their work is published in the journal Nature Materials. —Huang et al.

Georgia Tech team develops highly efficient multi-phase catalyst for SOFCs and other energy storage and conversion systems

Green Car Congress

The catalyst is also readily applicable to other energy storage and conversion systems, including metal-air batteries, supercapacitors, electrolyzers, dye-sensitized solar cells, and photocatalysis. The catalyst is applied as a sheer coating only about two dozen nanometers thick and comprises two connected nanotechnology solutions.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE. Schüttauf et al.
