Carbogel anode materials and method for their preparation are disclosed. The described carbogels exhibit, at a temperature of 20&#xb0; C., an electrical conductance of at least 0.5 S/cm and a reversible electrochemical capacity in relation to lithium of at least 350 mAh/g under a C/2 discharge current, enabling their use for preparation of anode materials, particularly those intended for preparation of lithium-ion cells.

LKMNO cathode materials based on a lithium-manganese spinel modified synergetically with potassium and nickel, and a method of production thereof are disclosed. The LKMNO cathode materials are characterised by a reversible gravimetric capacity in relation to lithium of at least 250 mAh/g after 80 operation cycles under a current load of 1 C, so that they are suitable for application in lithium-ion batteries with a high energy density.

A process for the preparation of carbon layers on powdered supports comprising dissolving a hydrophilic polymer (PH) at the level of 85 do 99.9% by weight in water, adding pyromellitic acid (PMA) or pyromellitic dianhydride (PMDA) at the level of 0.1-15% by weight, then introducing to the mixture the powdered support at a level of 1-99% by weight. The suspension is concentrated and dried, and the composite precursor formed is subjected to a pyrolysis process at 300-1500&#xb0; C.
