“At certain ratios, we find evidence of a covalent linkage between the inorganic and polymer. At certain ratios, we find evidence of a covalent linkage between the inorganic and polymer,” said researchers.
They also showcased the material in a lithium metal battery where their in situ material has improved mechanical properties and superior ionic conductivity and cycling performance against Li–metal, in comparison to an ex situ polymer + sulfide control.
