Batt-TDS™ inducts powders under vacuum into a stream of liquid, thereby creating conditions for optimal
dispersion of diverse components in a continuous sequence.


Process sequence for slurry preparation with a Batt-TDS.


a) Images of an attempt to dissolve Solef 5130 (Solvay) PVDF powder (8.2 wt%) in NMP for 60 min vs
b) 3 min after powder induction with a Conti-TDS (<1 min) at room temperature.
c) Illustration of deagglomeration of carbon black
d) a C65 (Imerys) carbon black paste produced by dispersing carbon black in an NMP solution of PVDF (1:1 C65:Solef 5130, 11 wt% in NMP).


Performance comparison of NMC 622 /graphite cells with cathodes made with a Batt-TDS for 1 min after powder
induction vs a planetary mixer for 2.5 h:
a) long-term cell cycling, b) internal resistance, c) Coulombic efficiency with 2C/3C charge/discharge rates, respectively.
