UCLA team uses graphite to boost performance of lithium iron phosphate cathode materials

Green Car Congress

Lithium iron phosphate (LiFePO 4 ) is widely used as a low-cost, safer cathode material for Li-ion batteries; however, low ionic and electronic conductivity limit its rate performance. The approach provides a new strategy toward low-cost, long-life, and high-power batteries, the researchers concluded.

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.
