Porosity of the cathode during the discharge of SOCl2/Li batteries: I. Industrial cathodes

摘要: Abstract During the discharge of Li/SOCl 2 batteries, morphology cathode (mainly compacted conductive carbon black) is modified by two phenomena producing opposite effects. LiCl precipitates in porosity reducing pore volume. The electrode swells increasing It difficult to identify contribution both phenomena. was shown mercury porosimetry that deposits mainly at entrance pores with diameter higher than 200 nm (pore constrictions); size distribution shifts smaller centered on 50 nm. Later, narrow mesopores and supermicropores.
