      abstract     = {In this work, the suitability of the spinel material
                      ZnFe2O4, which has already been widely investigated in the
                      context of its magnetic and photocatalytic properties, for
                      use as active material for the cathode side in zinc ion
                      batteries is presented. In addition to pure ZnFe2O4, part of
                      the Fe³⁺ was doped with Ti⁴⁺ to achieve stabilization
                      of Zn vacancies in the material and increase ionic
                      conductivity as indicated by previous modelling results.
                      Ceramic samples with the composition ZnFe2−xTixO4 (x = 0
                      to 0.25) were prepared via a Pechini synthesis route and
                      investigated regarding their optical, structural and
                      electrochemical characteristics. It has been successfully
                      demonstrated that both pure and Ti doped ZnFe2O4 can be used
                      as active material in the positive electrodes of zinc metal
                      batteries or in an “anode-free” setup with Sn metal.

                      triflate in acetonitrile|Zn showed a stable cycling behavior
                      over 1000 cycles and an average initial specific capacity of
