Battery Cathodes Being Made Using Sol-gel Method

Researchers from Thailand studied the use of the sol-gel method to produce lithium battery cathodes from a new material and their findings are in the online materials journal AZojomo.

For some time LiNiO2 has been a promising cathode material due to its large discharge capacity and low cost. Unfortunately traditional reactions used to make the material are difficult to control in relation to stoichiometry and grain size distribution. The sol-gel method allows easier control over stoichiometry, submicron-size particles and good homogeneity while being faster and done at lower temperatures. The purpose of this research is to find the optimum condition for preparation of Li1-x Ni1+x O2 powder by a sol-gel method with subsequent calcination at different temperature and time in air. The optimum condition was determined in order to obtain the product with the best electrochemical performance.
