      abstract     = {The development of high safety lithium-ion batteries (LIBs)
                      is greatly impeded by the flammability and leakage concerns
                      of typical organic solvent-based electrolytes. As one of the
                      alternative classes of electrolytes, hydrogel electrolytes
                      exhibit high safety, high flexibility, low cost, and are
                      benign to the environment. However, the narrow
                      electrochemical stability window (ESW) of typical hydrogel
                      electrolytes restricts the operating voltage of battery
                      cells. Here, a new class of “water-in-eutectogel
                      (WiETG)” electrolyte is reported, fabricated by combining
                      a hydrogel with a “deep eutectic solvent” (LiTFSI in
                      acetamide). The obtained WiETG electrolyte exhibits
                      non-flammability, high ionic conductivity, and a wide ESW.
                      LiMn2O4||Li4Ti5O12 cells with the WiETG electrolyte exhibit
                      good cycling stability, high flexibility, and high safety.
                      This newly developed WiETG electrolyte not only broadens the
                      ESW of typical hydrogel electrolytes, but also opens a new
                      perspective on future directions and guidance for the design
                      of high safety electrolytes for flexible LIBs and beyond.},
