水系鋅離子電池導(dǎo)電聚合物基正極材料的制備與性能研究

水系鋅離子電池導(dǎo)電聚合物基正極材料的制備與性能研究摘要：

水系鋅離子電池是一種新型的可充電離子電池，具有高穩(wěn)定性、高安全性、低成本等優(yōu)點(diǎn)。聚合物基正極材料是水系鋅離子電池的重要組成部分，制備具有較高導(dǎo)電性和優(yōu)異性能的聚合物基正極材料對(duì)于鋅離子電池的性能和應(yīng)用具有重要意義。本文以聚合物電解質(zhì)PVA/H2SO4為導(dǎo)電基質(zhì)，采用界面聚合法制備了混合聚合物材料，并通過(guò)結(jié)構(gòu)表征、電化學(xué)測(cè)試和性能測(cè)試，研究了制備條件對(duì)于聚合物基正極材料的影響。結(jié)果表明，PVA/H2SO4基質(zhì)中引入苯乙烯單體，并通過(guò)交聯(lián)反應(yīng)制備得到的正極材料具有較高的導(dǎo)電性和優(yōu)異的電化學(xué)性能，同時(shí)具有很好的穩(wěn)定性和透明度。本研究為水系鋅離子電池的應(yīng)用和開(kāi)發(fā)提供了重要的參考。
