Over the past decade, significant advancements have transformed AZIBs into rechargeable systems with improved cycling stability and energy density.
The technological trajectory of AZIBs has been marked by continuous improvements in electrode materials, electrolyte compositions, and cell architectures. However, a persistent challenge limiting their commercial viability is hydrogen evolution during charging processes. This parasitic reaction not only reduces coulombic efficiency but also leads to electrolyte depletion, internal pressure buildup, and eventual battery failure.
Electrolyte additives represent a strategic approach to mitigate hydrogen evolution without compromising the fundamental advantages of aqueous systems. The development of these additives has progressed from simple pH buffers to sophisticated organic and inorganic compounds designed to modify the electrode-electrolyte interface dynamics. Recent research indicates that properly designed additives can significantly suppress hydrogen evolution while simultaneously enhancing zinc deposition morphology.
The technological objectives for electrolyte additives in AZIBs are multifaceted. Primary goals include achieving near-complete suppression of hydrogen evolution across wide voltage windows, ensuring compatibility with various cathode chemistries, and maintaining effectiveness throughout extended cycling. Additionally, these additives should be cost-effective, environmentally benign, and amenable to large-scale manufacturing processes.

Current Challenges in Hydrogen Evolution Suppression
Hydrogen evolution reaction (HER) represents one of the most critical challenges in aqueous zinc ion batteries (AZIBs), significantly hindering their practical application and commercial viability. This parasitic reaction occurs at the zinc anode surface during charging processes, consuming electrolyte water molecules and generating hydrogen gas. The consequences are multifaceted and severely detrimental to battery performance.
The primary challenge stems from the thermodynamic instability of zinc metal in aqueous environments. With a standard reduction potential of -0.76 V vs. SHE, zinc readily reacts with water, particularly at charging voltages. This fundamental incompatibility creates an inherent hurdle for electrolyte design that must balance electrochemical performance with stability.
Current electrolyte systems face significant limitations in suppressing hydrogen evolution. Conventional zinc salt solutions (ZnSO₄, Zn(CF₃SO₃)₂, etc.) provide insufficient protection against HER, resulting in low Coulombic efficiency, typically below 90% in practical applications. This inefficiency translates directly to capacity loss and shortened cycle life.
The hydrogen gas generated during HER creates additional mechanical complications within the battery architecture. Gas accumulation leads to increased internal pressure, causing electrolyte leakage, cell swelling, and in extreme cases, safety hazards. Furthermore, the bubbles formed at the electrode-electrolyte interface disrupt the uniform zinc deposition process, exacerbating dendrite formation.
Existing additive approaches demonstrate limited effectiveness across broad operating conditions. Many current additives function well in narrow voltage windows or specific temperature ranges but fail to provide comprehensive protection. For instance, organic additives like polyethylene glycol show promising HER suppression at room temperature but lose effectiveness at elevated temperatures or extended cycling.
The concentration paradox presents another significant challenge. Higher zinc salt concentrations can suppress HER through reduced water activity but simultaneously increase electrolyte viscosity and decrease ionic conductivity. This trade-off between HER suppression and electrochemical performance creates a narrow operational window that limits practical applications.
Additionally, many effective HER suppressants negatively impact other critical battery parameters. For example, certain metal ion additives that effectively suppress hydrogen evolution may simultaneously accelerate cathode dissolution or trigger unwanted side reactions. This interconnected nature of electrolyte components makes isolated optimization of HER suppression particularly challenging.
The economic viability of additive solutions also presents a significant barrier. Many effective additives are prohibitively expensive for large-scale implementation or involve complex synthesis procedures that limit commercial scalability. The ideal additive must balance technical performance with cost-effectiveness to enable practical commercialization of AZIBs.

Environmental Impact Assessment of Electrolyte Additives
The environmental impact of electrolyte additives in aqueous zinc ion batteries (AZIBs) requires comprehensive assessment, particularly as these technologies gain prominence in sustainable energy storage solutions. Additives used for hydrogen evolution suppression, while beneficial for battery performance, introduce complex environmental considerations throughout their lifecycle.
Primary environmental concerns include the extraction and processing of raw materials for these additives. Many effective hydrogen evolution suppressors contain rare earth elements or transition metals that require energy-intensive mining operations. These processes often result in habitat disruption, soil degradation, and potential water contamination. For instance, fluorinated additives, while effective at stabilizing the electrode-electrolyte interface, pose significant environmental persistence concerns.
Manufacturing processes for specialized electrolyte additives typically involve chemical synthesis routes that may generate hazardous byproducts. Organic additives such as polyethylene glycol and thiourea derivatives require solvents and catalysts that must be properly managed to prevent environmental release. The energy footprint of these manufacturing processes contributes to the overall environmental impact, though it remains significantly lower than that of traditional lithium-ion battery components.
During battery operation, the environmental profile of these additives appears favorable. By suppressing hydrogen evolution, they reduce gas generation and improve energy efficiency, indirectly lowering the carbon footprint of the energy storage system. Additives that enable longer cycle life and improved stability effectively reduce the environmental burden by extending battery service life and decreasing replacement frequency.
End-of-life considerations present significant challenges. Current recycling infrastructure is not optimized for recovering specialized additives from spent electrolytes. Water-soluble additives may enter wastewater streams if improper disposal occurs, potentially affecting aquatic ecosystems. Biodegradability varies significantly among different additive classes, with organic compounds generally offering better environmental fate profiles than metal-based or fluorinated alternatives.
Regulatory frameworks for these materials remain underdeveloped in many regions, creating uncertainty regarding proper handling and disposal protocols. Life cycle assessment studies specifically targeting electrolyte additives in AZIBs are limited, highlighting a critical knowledge gap that requires attention as these technologies approach commercial scale.
Future development should prioritize green chemistry principles in additive design, focusing on biodegradable alternatives derived from renewable feedstocks while maintaining hydrogen suppression efficacy. This balanced approach would optimize battery performance while minimizing environmental footprint across the product lifecycle.
