Abstract: An electrode structure of a flow battery. A density of the vertical tow in the electrode fiber is larger than the density of the parallel tow. In the electrode fiber per unit volume, the quantity ratio of the vertical tow to the parallel tow is at least 6:4. The electrode structure includes an odd number of layers of the electrode fibers, and the porosity of other layers is larger than that of the center layer. The electrode structure includes the vertical tows, so that, the contact area between the outer surface of the electrode and the adjacent component is increased and the contact resistance is reduced; the electrode has good mechanical properties; the contact resistance of such structure is reduced by 30%-50%; and the layers of the electrode have different thickness depending on the porosity. After compression, the layers with optimized thickness have a consistent porosity.

Abstract: A direct structured illumination microscopy (dSIM) reconstruction method is provided. First, a time domain modulation signal is extracted through a wavelet. Then, an incoherent signal is converted into a coherent signal. Next, an accumulation amount at each pixel is calculated. Finally, a super-resolution image is generated by using a correlation between signals at different spatial positions. An autocorrelation algorithm of dSIM is insensitive to an error of a reconstruction parameter. dSIM bypasses a complex frequency domain operation in structured illumination microscopy (SIM) image reconstruction, and prevents an artifact caused by the parameter error in the frequency domain operation. The dSIM algorithm has high adaptability and can be used in laboratory SIM, nonlinear SIM imaging systems, or commercial systems.
