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.

High capacity germanium oxide/germanium nanocomposite for Li-ion anode material

Green Car Congress

Korea, have developed a germanium oxide/germanium nanocomposite (GeO 2 /Ge/C) anode material for Li-ion batteries that shows a high capacity of up to 1860 mAh/g at 1 C (2.1 In addition, there is widespread belief that, during the first lithiation, Li 2 O is irreversibly formed. Li+ per GeO 2 (1126 mAh/g) compared to 8.4

Researchers propose reason for capacity loss in metal-oxide battery materials

Green Car Congress

Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies. Magnetite, among other conversion-type electrode materials (i.e., However, their capacity fades very rapidly.
