Dual Fiber Electrode Mat for Batteries and Applications of the Same
A dual fiber mat for making an electrode includes first nanofibers and second nanofibers. The first fibers contain particles for electrochemical reaction and a binder. The second fibers contain particles for electron conduction and a binder. For a Li-ion battery anode, the first fibers include a polymer binder composed of an electron conducting polyfluorene derivative polymer (PFM or PEFM) or PVDF or PAA and silicon nanoparticles or silicon nanorods embedded in the binder. For a Li-ion battery cathode, the first fibers include a binder composed of an electron conducting polymer (PFM or PEFM) or PAA or PVDF and LiCoO2 or LiFePO4 or Li2MnO3 particles embedded in the binder. The second nanofibers include a PFM or PEFM binder or non-conductive polymer binder and electrically conductive nanoparticles embedded in the binder. The dual fiber mat has a thickness in a range of about 50-1000 μm.
