Stationary semi-solid battery module and method of manufacture

Abstract

An electrochemical cell includes an anode, a semi-solid cathode, and a separator disposed therebetween. The semi-solid cathode includes a porous current collector and a suspension of an active material and a conductive material disposed in a non-aqueous liquid electrolyte. The porous current collector is at least partially disposed within the suspension such that the suspension substantially encapsulates the porous current collector.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of US Provisional Application Serial No. 61 / 531,927, entitled "Battery Manufacturing Method," filed September 7, 2011, which is hereby incorporated by reference in its entirety. Background technique [0003] Embodiments described herein relate generally to the preparation of electrode cells for electrochemical devices, and more particularly to systems and methods for using semi-solid electrode cells with porous current collectors in battery modules. [0004] Conventional battery systems store electrochemical energy by separating ion sources and ion sinks at different ion electrochemical potentials. The difference in electrochemical potential produces a voltage difference between the positive and negative electrodes which, if the electrodes are connected by a conductive element, produces an electric current. In a conventional battery system, the negative and positive electr...
