Description
Summary:Optimized performance of silicon‐ionic‐ liquid lithium‐ion batteries through the implementation of a new electrode‐microgeometry. The incorporation of 1D silicon nanowires into the cyclized‐polyacrylonitrile‐based electrode‐architecture allows for greatly improved active material utilization, higher rate capabilities, and reduced interfacial reactions.
