Investigation of gas concentration cell based on LiSiPO electrolyte and Li2CO3, Au electrode
Solid lithium ion conducting electrochemical cells using LiSiPO as solid electrolyte and Li2CO3 mixed with Au as electrodes were prepared and employed as chemical sensors for the detection of CO2 gas. The EMF of the cell depends on the concentration of CO2 in air according to the partial pressure dependence of Nernst’s law in the investigated range from 100 to 2000 ppm over the temperature range from 473 K to 673 K.
