A method reduces internal resistance of a battery (). In the method, a charging current is directed to a battery (), where the charging current includes spin-polarized and charged electrons. A dedicated spin generator () is capable of providing the charging current including spin-polarized and charged electrons. Next, the battery () has been manufactured so that the battery includes either ferroelectric or pyroelectric material at least either in an anode (), in a cathode (), or in an other element of the battery (). The material can be selected to be polyvinylidene fluoride ('PVDF') or modified materials thereof. After at least one cycle of charging of the battery (), the battery () with reduced internal resistance is obtained.

The present invention discloses a method for creating spin-affected electric currents passively and feeding them into electric devices. The invention can be realized as either a rectangular black box incorporating coatings on top of and on the bottom of a conducting volume of material, or by coating a round-shaped wire or thread(s) of a cable. This is obtained by using a specific coating material on the conducting piece of material. The material may be piezoelectric, such as silicon dioxide (i.e. quartz) but also silicon carbide (SiC) may be used. Also, mixtures and composite arrangements are possible in order to create a coating. The manufactured add-on unit, when supplied with the input power or input signal, will act as an electron spin feeding device to the electric device because the electrons will be moving strongly within the interface area of the coating and the conducting material with aligned spins. The resulting effect also lasts longer within the electric device than just the time when the add-on unit is connected to the electric device.
