“…LiMn 2 O 4 electrodes can be prepared using following conditions: precursor solution: Mn(NO 3 ) 2 .4H 2 O (50 mmol/l) and LiNO 3 (25 mmol/l) in ethanol, flow: 0.5 ml/h, deposition time: 30 minutes, U HV : 5.1 kV., substrate temperature: 400°C. Electrodes prepared in that way can also be used for investigations by the electrochemical quartz microbalance (ECQM), measuring mass changes of the electrode [2], as well as for the electrochemical mass spectrometry (EMS), detecting volatile compounds appearing during film formation or decomposition of the used electrolyte [3].…”
