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.

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. The predicted resource gain in comparison with the direct current charge, while using the device of automated storage batteries charge with asymmetric current is confirmed, as well as decrease in the mode of the heating-up charge, and the fall-off in gas emission intensity.
