Ceramic diaphragm as well as preparation method and application thereof
The invention discloses a ceramic diaphragm as well as a preparation method and application thereof. The ceramic diaphragm comprises the following components: a sol-gel agent, a buffering agent, a pore forming agent, a corrosive agent and water, the sol-gel agent is n-butyl titanate; the buffering agent is triethanolamine; the pore forming agent is nano silicon dioxide microspheres; the corrosive agent is selected from at least one of sodium hydroxide, potassium hydroxide and hydrofluoric acid. According to the diaphragm prepared by the invention, the internal resistance of the battery can be effectively reduced through accumulation of high-concentration sulfuric acid electrolyte in gaps (solving the problem of electrolyte layering) and ultralow ion conduction internal resistance, the utilization rate of active substances is improved, and the service life of the battery is further prolonged.
本申请公开了一种陶瓷隔膜、制备方法及其应用，所述陶瓷隔膜的成分包括溶胶凝胶剂、缓冲剂、造孔剂、腐蚀剂和水；所述溶胶凝胶剂为钛酸正丁酯；所述缓冲剂为三乙醇胺；所述造孔剂为纳米二氧化硅微球；所述腐蚀剂选自氢氧化钠、氢氧化钾、氢氟酸中的至少一种。本申请所制备的隔膜可以通过空隙内对高浓度硫酸电解液的蓄积(解决电解液分层问题)以及超低的离子传导内阻而有效降低电池内阻，提升活性物质利用率，进而延长电池使用寿命。
