Abstract
The present application discloses boron-doped lithium rich manganese based materials for cathodes of lithium ion batteries. The disclosed cathode materials can be prepared by co-precipitation and sol-gel methods. The chemical formula of this cathode material is Li[LiMnCoNiB]O(a+b+c+d+x=1, a, b, x>0, c≧0, d≧0, c+d>0). Lithium ion batteries using these cathode materials show impressive improvements in performance and increased tap density at low level of boron doping. The co-precipitation method is particularly suitable for large-scale industrial production. The sol-gel method is simple and can produce fine and uniform particles.
