Samples of cathode material were synthesized from a highly dispersed precursor containing 0.002 at.% Sr. The synthesis was performed from a mixture of the precursor with some overstoichiometric excess of LiOH at 720 °C in oxygen atmosphere. Part of

A simple method for the synthesis of LiNi 1− y Co y O 2 with y =0.2–0.3 is developed based on the solid state reaction between LiOH and a mixed oxide precursor, Ni 1− y Co y O 2 , with a high dispersity and a homogeneous distribution of Ni and

A method for the in situ dynamic measurement of the Ohmic resistivity, Rc, of LiNi1−y CoyO2 cathodes as a function of the state of discharge, x, is developed. It follows the evolution of Rc with only a negligible interference of the discharge proce

A number of criterial specific parameters of the electrodes in five commercial Li ion batteries of leading producers are derived on the basis of the recently published data by Johnson and White [B.A. Johnson, R.E. White, J. Power Sources 70 (1998) 48

The synthesis and XRD characterization of overlithiated LiNiO2 samples is briefly described. The effect of the extraction of the residual LiOH from the samples after their synthesis is studied. The extraction in water even at a low liquid/solid ratio

The synthesis of LiNiO2 in air is studied by means of X-ray diffraction (XRD) characterization using a new fast method based on the splitting of the (108) and (110) peaks and the depth of the minimum between these peaks. From the evolution of these X

A method is described for the estimation of the volumetric specific capacity of balanced Li-ion cells. The effect of the material balance or the cathode/anode mass ratio, r, in Li-ion cells on the volumetric specific capacity, qv, of the electrode pa

The storage characteristics of Li accumulators with three different cathode materials , , and are studied. A capacity loss of 4–10% per month at room temperature in ether‐based electrolytes is observed. This rate depends on the impurity level of
