氧化锡锑/二氧化钛/木棉碳改性凝胶电解质的制备及性能
Preparation and properties of antimony-doped tin oxide/titanium dioxide/kapok carbon modified gel electrolyte
摘要
Abstract
Polyvinyl alcohol(PVA)was used as the matrix of hydrogel electrolyte.The conductivity of the hydrogel electrolyte was improved by adding antimony-doped tin oxide(ATO).Nanoparticulate titanium dioxide(TiO2)and kapok carbon(KC)were introduced to interact with the hydroxyl groups in PVA,forming a three-dimensional channel network,which improved the structure of the hydrogel electrolyte and enhanced its ion transport capacity and electrochemical stability.The test results show that the ionic conductivity of the PVA/ATO/TiO₂/KC hydrogel electrolyte is 1.61 mS/cm,with a corrosion potential(Ecorr)of 0.517 V and a corrosion current(Icorr)of 0.003 42 mA.For the correspond-ing full cell under 1 C condition,the initial specific capacity is 148.3 mAh/g,and the capacity reten-tion rate after 300 cycles is 90.7%.In addition,zinc deposition on the anode is relatively uniform,which alleviates the dendrite growth.The modified hydrogel electrolyte significantly improves the cycle stability and electrochemical reversibility of the battery.关键词
