New Battery Can Self-Charge Without Losing Energy
Researchers use a ferroelectric glass electrolyte within an electrochemical cell to create simple self-charging batteries. The ferroelectric character of the electrolyte, with an impressively high dielectric constant of 106–107, supportes self-oscillation due to negative resistance and negative capacitance. Negative capacitance is due to the formation of an inverted capacitor between the double-layer capacitor formed at the negative electrode/electrolyte interface and the dipoles of the ferroelectric-electrolyte. Negative resistance is triggered by the formation of an interface phase, which leads to a step-change of the chemical potential of the electrode.
Illustrations indicate, that this battery uses stochastic resonance of double layer) of ferroelectric glass electrolyte within an electrochemical cell for recharging. . If confirmed, it could be a great thing - not only from practical, but also from ideological reasons, because overunity devices are still ignored and denied by mainstream journals and science.
Stochastic resonance (SR) is a phenomenon where a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies. An overdamped particle in a periodically oscillating double-well potential is subjected to Gaussian white noise, which induces transitions between the potential wells. We again have cyclic process which has activation barrier assisted by random noise. Further, the added white noise can be filtered out of signal to effectively detect the original, previously undetectable signal. This phenomenon extends to many other systems - whether electromagnetic, physical or biological - and is an area of intense research. See also:
