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. Resources.

Japanese start-up seeks to commercialize dual-carbon battery technology; anion intercalation

Green Car Congress

Start-up Power Japan Plus announced plans to commercialize a dual-carbon battery technology, which it calls the Ryden dual carbon battery. Dual-carbon (also called dual-graphite) batteries were first introduced by McCullough and his colleagues at Dow Chemical in a 1989 patent, and were subsequently studied by Carlin et al.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The high energy storage has stimulated a worldwide study of Li-air batteries. A typical Li-air battery discharges at 2.5-2.7 V vs. Li/Li + at room temperature.
