Abstract: As a cathode material for lithium ion batteries, LiNiO2 has various drawbacks such as difficulty to be
synthesized, poor cycling performance and poor thermal stability, which are all related to its crystal structure. Stared from the crystal structure,
this paper analyzed the causes that result in these drawbacks and reviewed the improve ways briefly. It was shown that just optimizing the synthesis
conditions could only improve the cycling performance to a degree. In order to overcome these drawbacks thoroughly, the most important thing is to
stabilize the layered structure of LiNiO2 by part substitution of suitable elements for nickel or/and oxygen.

Key words: lithium ion batteries, cathode, LiNiO_2, drawbacks, improve ways
