The application provides a high-efficiency synergic driving artificial muscle fiber pair, a driving method and application thereof. The artificial muscle fiber pair comprises an artificial muscle fiber as a working electrode, an artificial muscle fiber as a counter electrode and an organic electrolyte; the material and structural parameters of the two artificial muscle fibers are consistent; and the electrolyte is selected from a salt composed of a full alkyl ammonium cation and a perfluoroboric acid anion and / or a perfluorophosphoric acid anion. The application uses the anion-cation salt with symmetric driving properties as the electrolyte, uses two artificial muscle fibers with consistent material parameters as the positive electrode and the negative electrode, and uses the synchronous driving electrochemical fiber pair system, so that the synchronous contraction is realized under the positive and negative potentials, the positive and negative electrodes are active working units in the whole driving cycle, the problem of "counter electrode idling" is completely overcome, the overall output work and energy conversion efficiency are greatly improved, the driving asynchronization or mechanical stress accumulation is effectively avoided, and the cycle stability and response consistency are improved.

The application pertains to processes for producing alkali hydroxides or alkali sulfites using large molecular weight acid intermediates. Generally, a component comprising an alkaline-earth cation—small molecular weight acid anion may be reacted with a component comprising an alkali sulfate to form a component comprising an alkali cation—small molecular weight acid anion and a component comprising an alkaline-earth sulfate. A series of additional steps results in forming a component comprising an alkali hydroxide, or an alkali carbonate, or an alkali bicarbonate, or any combination thereof.
