Effects on response and recovery behaviors depending on reference materials such as lithium cobalt oxide (LiCoO2) and lithium manganese oxide (LiMn2O4) as well as lithium titanate (Li2TiO3) were investigated by fabricating the sensor composed of those reference materials and a sensing material Li2CO3 on a solid electrolyte Li3PO4. Selection of the reference materials was adopted from cathode materials in lithium ion battery field because of the similar working mechanism. The results showed that LiMn2O4 and...
