Enhanced Li super(+) ion transport in LiNi sub(0.5)Mn sub(1.5)O sub(4) through control of site disorder

High voltage spinel LiNi sub(0.5)Mn sub(1.5)O sub(4) is a very promising cathode material for lithium ion batteries that can be used to power hybrid electrical vehicles (HEVs). Through careful control of the cooling rate after high temperature calcination, LiNi sub(0.5)Mn sub(1.5)O sub(4) spinels wi...

Description
Summary:High voltage spinel LiNi sub(0.5)Mn sub(1.5)O sub(4) is a very promising cathode material for lithium ion batteries that can be used to power hybrid electrical vehicles (HEVs). Through careful control of the cooling rate after high temperature calcination, LiNi sub(0.5)Mn sub(1.5)O sub(4) spinels with different disordered phase and/or Mn super(3+) contents have been synthesized. It is revealed that during the slow cooling process (
