  ABSTRACT: Hybrid capacitive deionization (HCDI) is an emerging and
  promising technology for water desalination and has been extensively explored
  in recent years. Designing a structure-tailorable electrode material has been proved
  to be a valid strategy for achieving a higher salt adsorption capacity (SAC). In this
  study, MnO2 materials with tailorable phase compositions and crystallinities were
  prepared hydrothermally and then evaluated as electrodes for removal of ions from
  a NaCl solution in a membrane-free HCDI cell. MnO2 electrode materials tested
  in the HCDI system include poorly crystalline δ-MnO2 along with abundant
  amorphous phases (MnO2-1h); cr
