The invention relates to the field of energy, more specifically to the means of accumulation, storage and separation or conversion of thermal energy.

Known accumulators of heat energy: liquid thermal batteries, thermal batteries with solid heat storage material, heat accumulators, based on phase transitions [1] [2]. Batteries, thermal energy, based on phase transitions, and containing at least one control element and the working body, allow accumulation of thermal energy and having the possibility of heat release, are the closest in technical essence to declared.

The disadvantage of all known from the prior art counterparts, including the closest, is relatively low consumption of battery thermal energy

The present invention is directed to overcoming the difficulties of the known prior art and the creation of new battery thermal energy, characterized by a higher intensity.

This task is solved in that the battery heat, containing at least one control element and the working body, allow accumulation of thermal energy and having the possibility of heat release as a result of exposure at least real the control element, according to the invention the working fluid is an amorphous particles of refractory material providing a thermal storage while in the metastable state strongly disordered defective-rich condensed phase and heat energy is released during the phase transition from the defective-rich disordered condensed state into a crystalline array.

As a working body it is preferable to use particles of tungsten, rhenium, tantalum, molybdenum, niobium.

Preferably the control element is configured to activate the phase transition between the defective-rich and crystal-like States of the particles of the working fluid. For these purposes, as the control element or the control element can be used electrode providing an electric pulse to a working body to activate the phase transition of defective particles-rich disordered condensed state into a crystalline array.

A new element of the claimed battery heat itself is the working body - particles of refractory material (e.g. metal or oxide), physically located in a special, quasi-stable condition with abnormally high for a firm who ate the structural razuporyadochennogo as far, and the middle order. Such phase state can be achieved, in particular when recovering crystalline oxides of refractory metals cold injection selenophosphate protons [3]. The resulting particles recovered metal are classified as metastable defective-rich phase state of the type of highly supercooled liquids or deep frozen "gas".

Similar to the phase state of the particles of refractory metals are characterized by a unique energy thresholds between phase transitions that satisfy simultaneously two opposite conditions - stability defective-rich phase and a high energy overcoming the interphase barrier between defective-intense and crystalline phases.

The use of amorphous particles of refractory metals as energy-accumulating material is allowed to reach values of intensity, fold excess energy as existing thermal and electric batteries.

The use of amorphous particles of refractory materials as energy-accumulating material allows for a working body of the battery is a fundamentally new design solutions in the form of a thin composite materials. In turn, the battery heat the working fluid in the form of a thin composite materials with amorphous particles of refractory materials as energy-accumulating component allows fundamentally new design solutions for small power sources and small energy converters, significantly superior to existing devices on the intensity.

The invention is illustrated hereinafter in more detail a specific example of implementation with reference to the attached drawing, which shows a structural diagram of the described implementation of the battery according to the invention. Positions on the drawing: 1 - matrix of the honeycomb structure 2 - working body of the battery, 3 - mask, 4 - electrode, 5 - activating the cylinder, 6 - output wire, 7 - activating the electrode.

The battery in this particular case, its implementation, shown in figure 1, contains a matrix 1 honeycomb structure made of a chemically inert, non-conductive material with low heat conductivity, such as composites based on silicon or carbon. Cellular matrix 1 may have a rectangular or disc shape with a square-hole or spiral arrangement of the cells, respectively. The working body of the battery 2, which represents the particles of refractory metal (e.g. tungsten, rhenium, tantalum, molybdenum) in the high-energy state, is placed in each cell of the matrix 1.

One side of the cell matrix is covered by a mask 3 and available for external activation of the working fluid and removal emitted from the phase transition heat is the power by means of an electrode-heat exchanger 4. Activation of the working fluid and removal of heat may be a universal device - activating the cylinder 5. Activating the cylinder 5 may be made in the form of thermal energy Converter, such as described in [4], combined with an activating electrode 7 through which the working fluid is fed an electrical impulse that triggers a transition from a higher energy state at low energy. Allocated to the working fluid, thermal energy is converted activating head in electric directly in the process of taking energy from your body and is output to the output wire. Sequential activation of the cells with the working fluid, and removal of energy are carried out step-by-step movement of the matrix relative to the activating head, or activating head relative to the matrix. Thus is achieved the ability to control the allocation and removal of thermal energy of the battery.

In conclusion, it should be noted that the described example is provided to illustrate the invention and in no way should be construed as limiting the scope of the claims. The specialist will be clear and other specific cases embodiment of the invention, which, despite some slight differences in the modes of implementation and/or the materials used, will be the, however, as the claimed invention, is characterized by the same set of essential features that are listed in the attached formula.
