电化学储能是目前建筑储能中实施性最大的方式之一,水泥基电池为结构与储能的融合发展提供了创新途径.从电解质性能和制备方法两个方面,研究影响水泥基电池电化学性能的关键因素.以电阻率衡量水泥基材料的导电性能,对比研究了导电材料种类和掺量、含水率和水胶比对其性能的影响规律.结果表明,炭黑掺量10%、水胶比0.6为最佳水泥基材料配合比.同时,对水泥基电池的制备进行了优化试验,以体积能量密度衡量,金属体植入法>金属涂层法>粉末混合法,其中粉末混合法制备方法简单,金属体植入法储存能量多,金属涂层法可进行二次充放电.
Study on Electrolyte Performance and Battery Preparation Techniques of Cement-Based Batteries
Electrochemical energy storage is one of the most feasible approaches for building energy storage.Cement-based batteries offer an innovative solution for the integration of structure and energy storage.The key factors affecting the electrochemical performance of cement-based batteries are examined from two perspectives:electrolyte performance and preparation techniques.The electrical conductivity of cement-based materials is evaluated through resistivity,and the effects of conductive material types and contents,water content,and water-binder ratio on their properties are compared.The results indicate that a carbon black content of 10%and a water-binder ratio of 0.6 represent the optimal mix for cement-based materials.Additionally,the preparation process for cement-based batteries is optimized.Based on volume energy density measurements,the ranking is as follows:metal implant technique>metal coating technique>powder mixing technique.The powder mixing technique is the simplest,the metal implant technique stores more energy,and the metal coating technique allows for secondary charge and discharge.
