Achieving a long-term-stable Zn anode with a high utilization rate is highly desirable for practical high-energy-density zinc-ion batteries but remains a huge challenge. Although many artificial film-coated Zn electrodes with improved cycling ability have been developed, they only work efficiently under a low depth of discharge because of the limited capability of ion distribution regulation. During repeated Zn plating and stripping, huge heat will be generated, which increases the local temperature and accelerates local reaction kinetics. Such local “hotspots” will inevitably lead to uncontrollable dendrite growth and severe side reactions, especially under high current densities and capacities; thus, the Zn anode can be hardly cycled at high rates and a high depth of discharge. Here, a thermal transfer-enhanced strategy is proposed for a stable Zn anode with a high utilization rate, where the coating layers not only inhibit corrosion and side reactions but also drastically accelerate heat transfer, thus effectively eliminating local hotspots and preventing dendrite growth. The full battery exhibits both stable cycling performance and high energy density, which offers promising potential for practical applications.
