Recent advances and perspectives for Zn-based batteries: Zn anode and electrolyte

Abstract

Zn-based batteries have attracted extensive attention due to their high theoretical energy density, safety, abundant resources, environmental friendliness, and low cost. They are a new energy storage and conversion technology with significant development potential and have been widely used in renewable energy and portable electronic devices. Considerable attempts have been devoted to improving the performance of Zn-based batteries. Specifically, battery cycle life and energy efficiency can be improved by electrolyte modification and the construction of highly efficient rechargeable Zn anodes. This review compiles the progress of the research related to Zn anodes and electrolytes, especially in the last five years. This review will introduce fundamental concepts, summarize recent development, and inspire further systematic research for high-performance Zn-based batteries in the future.

Rose-shaped VS2nanosheets as cathode materials for rechargeable zinc ion batteries

“…In addition, the capacitance contribution rate of the electrode material is determined by the following formula: i ( V ) = k 1 V + k 2 V 1/2 ,where k 1 and k 2 are constant parameters, k 1 V and k 2 V 1/2 represent capacitance-controlled and diffusion-controlled reaction processes, respectively. 44 At 0.1, 0.2, 0.5, 0.8, and 1.0 mV s −1 , the capacitance contribution rates are 79.1, 81.2, 87.7, 90.2 and 92.0%, respectively (Fig. 4c).…”

“…HER, corrosion, and Zn dendrites would take place continuously on Zn/electrolyte interface (Fig. 1 a) [ 34 ]. Theoretically, HER and ZHS formation are significantly affected by the pH value of the electrolyte according to the following reactions [ 35 ]:

Recent Progress of Energy-Storage-Device-Integrated Sensing Systems

“…In contrast, sensing systems integrated with energy-storage devices can greatly avoid these drawbacks, and will work directly and effectively. Generally speaking, energy-storage devices come in a variety of types, such as batteries (lithium-based batteries [ 21 , 22 , 23 , 24 ], zinc-based batteries [ 25 , 26 ], and emerging biofuel cells [ 27 ]), supercapacitors [ 28 , 29 , 30 ], and hybrid devices [ 31 , 32 ]. In recent years, the flexible energy-storage devices that are compatible with sensor components have been developed with an increasingly mature manufacturing process, which provides more possibilities for wearable electronics in practical meaning.…”
