In article number 2000226 Majid Rasool, George P. Demopoulos, and co‐workers report the fabrication of a robust core‐shell lithium iron silicate (Li 2 FeSiO 4 , LFS) cathode architecture, where nanocrystal's core is prepared via mechanochemical annealing and shell via PEDOT polymerization. As a result of the devised mechanochemical/interphasial engineering of the LFS@PEDOT nanocrystals, their Li‐ion storage capacity is augmented to >1 Li, namely 200 mAh g −1 after 50 cycles or 1.2 Li + units‐the highest capacity reported for the Pmn 2 1 LFS cathode.
