Application of Potassium Ion Conducting KTiOPO₄ as Effective Inner Solid-Contact Layer in All-Solid-State Potassium Ion-Selective Electrode

Solid electrolytes used in all-solid-state batteries electronically separate the positive and negative electrodes battery only allow carrier ions to pass through. KTiOPO 4 (KTP), a potassium ion-conducting solid electrolyte, was first applied as inner contact layer of an ion-selective electrode (ISE) stabilize membrane potential. Application KTP improved long-term potential stability ISE by stabilizing This can be further adding acetylene black (AB) which reduced resistance owing its high double-layer capacitance.
