银钒磷氧化物(Ag2VO2PO4)作为正极材料,具有容量大、电流容量大、能有效传输大电流脉冲等显著的电化学性质。这些电池性能特征可以归因于在Ag2VO2PO4的电化学还原过程中原位形成的银纳米颗粒的存在。具体地说,详细描述了Ag2VO2PO4的组成和结构随还原过程的变化,特别是银纳米颗粒的形成,以合理地解释初始放电时电导率增加15,000倍的合理性,这可能与一次锂电池中与Ag2VO2PO4阴极相关的功率特性有关。
As a cathode material, silver vanadium phosphorous oxide (Ag2VO2PO4) displays several notable electrochemical properties: large capacity, high current capability, and an effective delivery of high current pulses. These cell performance characteristics can be attributed to the presence of silver nanoparticles formed in-situ during the electrochemical reduction of Ag2VO2PO4. Specifically, changes in the composition and structure of Ag2VO2PO4 with reduction, especially the formation of silver nanoparticles, are detailed to rationalize a 15,000 fold increase in conductivity with initial discharge, which can be related to the power characteristics associated with Ag2VO2PO4 cathodes in primary lithium batteries.
