Work is devoted to perspective materials for lithium accumulators. Low-volt cathodic materials are considered: lithium-vanadium bronze and litirovanny phosphates of metals. Methods of their synthesis with mechanoactivation use on the equipment of a high pressure like Bridzhmen\'s anvils are described. Pilot studies showed that thanks to mechanical activation it is possible to reduce annealing temperature by 300−500°C at achievement of a high-disperse condition of substance. Solid polymer electrolyte on the base of modified polysulfon, possessing high conductivity and adhesion to electrodes are considered. Their creation made actual development creation of the solid-phase accumulators possessing high specific energy and a resource, ability to accept any form. Perspective manufacturing techniques of electrodes with use of ultrasonic processing and mechanoactivation of its active weight which allow to raise significantly their characteristics, and also parameters of the lithium accumulator are described.
