Tailored Carbon Additives to Meet Requirements for High DCA and Low Water Loss - Wish and Reality - (PPT)

摘要

Two Correlations between laboratory half cell tests and DCA tests could be established: 1. Correlation between double-layer capacity and DCA: (1) The higher the double-layer capacity the higher the dynamic charge acceptance. 2. Correlation between DCA and hydrogen evolution: (1) Activation of DCA and HER occurs mostly in parallel; (2) In general: Higher DCA leads to higher gassing currents; (3) But: The ratio between gassing currents and DCA can be controlled.
