Abstract

Abstract Commercialization of aqueous batteries is mainly hampered by their low energy density, owing to the low mass loading of active cathode materials. In this work, a MnO2 cathode structure (MnO2/CTF) is designed to modify the MnO2/collector interface for enhanced ion transportation properties. Such a cathode can achieve ultrahigh mass loading of MnO2, large areal capacity, and high energy density, with excellent cycling stability and rate performance. Specifically, a 0.15 mm thick MnO2/CTF cathode can realize a mass loading of 20 mg cm−2 with almost 100% electrochemical conversion of MnO2, providing the maximum areal capacity of 12.08 mA h cm−2 and energy density of 191 W h kg−1 for Zn‐MnO2/CTF batteries when considering both cathode and anode. Besides the conventional low energy demonstrations, such a Zn‐MnO2/CTF battery is capable of realistic applications, such as mobile phones in our daily life, which is a promising alternative for wearable electronics.
