摘要
光催化有机液流电池可以将太阳能直接转化为化学能进行储存,兼具光催化技术和有机液流电池技术的优点。本文以光催化有机液流电池为研究对象,建立了一种全新的光催化有机液流电池数值计算模型,可以准确地预测光电流与多组分输运过程。基于本模型,研究了电解液流速和光强对光充电有机液流电池光电化学性能的影响。结果表明,增大电解液流量并不能提高电池光电化学性能。入射光光强的增加,电池的充电电压也上升,一定程度上提升电池的光电转化性能。本文对光催化有机液流电池的应用有重要的意义。
Photocatalytic organic liquid flow batteries can directly convert solar energy into chemical energy for storage,and have the advantages of both photocatalytic technology and organic liquid flow battery technology.In this paper,a new numerical calculation model for photocatalytic organic liquid flow batteries has been established,which can predict photocurrent and multicomponent transport processes accurately.Based on this model,the effects of electrolyte flow rate and light intensity on the photoelectrochemical properties of photocharged organic liquid flow batteries were studied.The results showed that increasing the electrolyte flow rate could not improve the photoelectrochemical performance of the battery.With the increase of incident light intensity,the charging voltage of the battery also increases,improving the photoelectric conversion performance of the battery to a certain extent.This article can contribute to the application of photocatalytic organic liquid flow batteries.
