Abstract: A double-sealed thin film electrochemical pouch cell, comprising a cathode current collector, a cathode, an electrolyte, an anode, and an anode current collector, which is double-sealed by a first inner laminate layer forming a primary seal covered by a second outer polymer layer forming a secondary seal. The second outer polymer layer comprises embedded particles to increase the thermal conductivity of the second outer polymer layer.

Abstract: The present disclosure relates generally to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. Electrodes produced according to the present disclosure feature narrow binder particle size distribution, which distinguishes such electrodes from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has an improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.
