In-Situ Magic: Revolutionizing Electrode/Electrolyte Interface Stability in Aqueous Zinc Batteries
- Scientists from Hunan University and Nankai University have discovered a new methodology to create robust EEI layers on the electrodes of aqueous zinc batteries (AZBs), which promises to improve battery stability by preventing side reactions.
- This groundbreaking methodology involves using glutamate additives to construct EEI layers on both cathodes and anodes.
- The glutamate additive undergoes a distinct self-polymerization process at both the cathode and anode to create a robust EEI layer.
- The resultant EEI layers exhibit an impressive efficacy in suppressing active material loss, inhibiting the growth of zinc dendrites and curbing the accumulation of by-products.
- The zinc || V₂O₅·nH₂O cells treated with the glutamate additive demonstrated superior rate capabilities and remarkable cycling stability, and retained 96.3% of initial capacity even after 1500 cycles under a current of 1 A g⁻¹.
- This interphase-forming additive is compatible with various cathode materials, opening avenues for developing durable and cost-effective aqueous rechargeable batteries.
- Advancements in aqueous zinc batteries could pave the way for more effective energy storage solutions tailored for clean and renewable sources of power and accelerate the integration of sustainable energy systems into daily life.
- The use of glutamate-based EEI layers not only promises enhanced battery performance but also aligns with the global vision of fostering greener technologies to propel us closer to a sustainable energy landscape.
- In conclusion, the study highlights the potential of glutamate additives in aqueous zinc batteries to meet an increasing demand for reliable and efficient battery technology and inspire a broader dialogue about the future of sustainable energy solutions.
- The research shows the significance of academic research in addressing real-world challenges and propelling us closer to a cleaner and more sustainable future.
