At this paper algorithms of accessible and full capacity estimation are presented. The model discrete parameter interpolation, based on spline function is shown. Presented algorithms are analyzed for use in real-time applications.
The review generalizes the literary data on physical-chemical and electrochemical properties of lithium-iron phosphate connected with perspectives of LiFePO4 use as a cathode material for lithium-ion batteries and published up to 2009 inclusive.
The methods of increasing performances of cathode materials based on lithium-manganese spinel are discussed in this review. Next questions are examined: the reasons of LiMn2O4 degradation and the basic variants of problem solving including the doping of spinel matrix by metal cations; the substitution of oxygen in system Li–Mn–O by another anions; the creation of protective shell on the surface of particles; the preparation of different composites. The possibility of working substitution's spinel matrixes in 5 V domain are demonstrated. The synthetic methods of stable and power-consuming lithium-manganese spinel are examined.
