The LiFePO4-electrode process features in Li-ion batteries

Features of lithiated iron phosphate behavior (PH/P1, Phostech Lithium Inc, Canada) used as positive electrode of lithium-ion battery with LiPF6-based electrolyte were investigated. It was shown that lihiated iron phosphate potential does not depend of lithium contents in active material. It was shown that cycle life of the positive electrode strongly depends on charge/discharge current. Fast degradation of the positive electrode takes place at low current rates (0.25 and 0.5C). At the same time degradation is considerably lower at 1 and 2.5C rates.

Automated rapid charge of the sealed nickel-cadmium storage batteries with asymmetric current, and its influence on the resource

The research results of the sealed nickel-cadmium storage batteries reliability at the rapid charge with asymmetric current are represented. In accordance with the reliability theory postulates, the experimental data of the resource test in the mode of the storage batteries 10NKGZ-1,8-1, 10NKGZ-3,5-l, 10NKGZ-4 cycling.
