8 Calendering of an electrode is a finishing process used to smooth a surface and to ensure good contact between particles of active material. The electrode is passed under rollers at high pressures. If the initial thickness and were 85 m (Ax) and we determined the path length (A/) through the electrode pores to be 105 um, calculate the tortuosity (1) if electrode is calendared to a thickness of 40m. (Please make sure to check lecture notes on Blackboard!). Your answer should be to three significant figures. 1 points Save
