  We propose a comprehensive set of indicators (including methods to obtain and
analyse them) for computational screening of candidate cathode materials for
rechargeable Zn-ion aqueous batteries relying on Zn$^{2+}$ intercalation
processes. The indicators capture feasibility of Zn$^{2+}$ intercalation and
transport within the material, the thermodynamic stability of charged and
discharged material structures, electrochemical stability of the cathode
material and electrolyte, volume expansion, and energy storage capacity. The
approach was applied to well-known cathode materials ($\alpha$-MnO$_2$ and
V$_2$O$_5$) as well as some potential alternatives (MoS$_2$, ZrP$_2$O$_7$,
MoO$_3$, and FeO$_2$) to demonstrate the screening workflow and the decision
making process. We show that selection of cathode materials for Zn-ion aqueous
rechargeable batteries is a multifaceted problem, and first principle
calculations can help to narrow down the search. Despite us being unable to
identify a particularly successful cathode material, tools and techniques
developed in this work can be applied more broadly to screen a wider array of
potential material compositions and structures, with the goal of identifying
next generation cathode materials for aqueous rechargeable batteries with the
intercalation energy storage mechanism not limited to Zn$^{2+}$ ions.
