发明名称 Electrochemical cells having a electrode current collector extending into a positive electrode composition, and related methods
摘要 An electrochemical cell is presented. The electrochemical cell includes an elongated ion-conducting separator defining at least a portion of a first compartment; a positive electrode composition disposed in the first compartment, the positive electrode composition comprising at least one electroactive metal, at least one alkali metal halide, and at least one electrolyte. A positive current collector is further disposed in the first compartment such that a portion of the positive current collector extends into the positive electrode composition, and a primary dimension of the extended portion of the positive current collector is less than about 20% of a primary dimension of the first compartment. A related method for the preparation of an electrochemical cell is also presented.

主权项 1. An electrochemical cell, comprising: (a) an elongated ion-conducting separator having a first surface that defines at least a portion of a first compartment and a second surface that defines at least a portion of a second compartment; (b) a positive electrode composition disposed in the first compartment, the positive electrode composition comprising at least one electroactive metal, at least one alkali metal halide, and at least one electrolyte; and (c) a positive current collector disposed in the first compartment such that an extended portion of the positive current collector extends into the positive electrode composition, wherein the first compartment is characterized by a primary dimension and the extended portion of the positive current collector is characterized by a primary dimension, and the primary dimension of the extended portion of the positive current collector is less than about 20% of the primary dimension of the first compartment.
