Recent advancements in zinc-ion battery technology are set to make a significant impact on various industries, particularly in the construction sector, where energy storage solutions are increasingly vital. Researchers from the State Key Laboratory of Metastable Materials Science and Technology at Yanshan University have introduced a groundbreaking bifunctional additive that enhances the performance of zinc sulfate (ZSO) electrolytes in these batteries.
Zhiqiang Dai, the lead author of the study published in *Energy Material Advances*, explained the critical role of this innovative additive, which combines ethylene glycol (EG) and sodium gluconate (Ga). “The polyhydroxy structures of EG and Ga not only stabilize the liquid electrolyte but also optimize the environment around hydrated Zn2+ ions,” he noted. This dual-functionality addresses common issues faced by traditional aqueous electrolyte systems, such as slow ion transfer and dendrite formation, which can lead to battery failures, especially in extreme temperatures.
The implications of this research extend beyond laboratory findings. With the capability to cycle for over 3,000 hours at 25 °C and 800 hours at 50 °C, the zinc anodes utilizing the 40% ZSO–Ga electrolyte present a significant leap in battery longevity. Furthermore, full batteries comprising Zn||NH4V4O10 (NVO) have demonstrated impressive cycle stability, enduring up to 10,000 cycles at a current density of 1 A g−1 with a capacity retention of 79.1%. This level of performance is crucial for industries like construction, where reliable energy storage can support the growing demand for sustainable building practices and renewable energy integration.
Dai emphasized the commercial potential of these findings, stating, “Our multifunctional electrolyte could revolutionize the way we approach energy storage in various applications, particularly in sectors that require robust and reliable battery solutions.” As construction projects increasingly incorporate renewable energy sources, the need for durable and efficient energy storage systems becomes paramount.
The introduction of such advanced battery technologies could enable construction firms to leverage renewable energy more effectively, reducing reliance on fossil fuels and promoting sustainable practices. This research not only showcases the potential of zinc-ion batteries but also aligns with global efforts to transition to cleaner energy solutions.
