      abstract     = {The introduction of “water-in-salt” electrolyte (WiSE)
                      concept opens a new horizon to aqueous electrochemistry that
                      is benefited from the formation of a solid-electrolyte
                      interphase (SEI). However, such SEI still faces multiple
                      challenges, including dissolution, mechanical damaging, and
                      incessant reforming, which result in poor cycling stability.
                      Here, we report a polymeric additive, polyacrylamide (PAM)
                      that effectively stabilizes the interphase in WiSE. With the
                      addition of 5 molar $\%$ PAM to 21 mol kg-1 LiTFSI
                      electrolyte, a LiMn2O4L-TiO2 full cell exhibits
                      enhanced cycling stability with $86\%$ capacity retention
                      after 100 cycles at 1 C. The formation mechanism and
                      evolution of PAM-assisted SEI was investigated using
                      operando small angle neutron scattering and density
                      functional theory (DFT) calculations, which reveal that PAM
                      minimizes the presence of free water molecules at the
                      anode/electrolyte interface, accelerates the TFSI- anion
                      decomposition, and densifies the SEI.},
