Synthesis and characterization of Li(LiyFezV1 − y − z)O2 − δ - cathode material for Li-ion batteries

Materials based on layered LiVO2 are mostly considered as a potential anodes for Li-ion batteries, competitive to commonly used graphite. They can also act as cathode materials, however there are almost no studies on this subject. LiVO2 and it delithiated derivatives were widely studied during 80s and 90s of the 20th century mainly because of its magnetic properties. This work presents evaluation of crystal structure, oxygen nonstoichiometry, transport and electrochemical properties of Li(LiyFezV1 − y − z)O2 − δ group of materials, with special insight to their possible application as cathode materials for lithium ion batteries.
