Embodiment Construction

[0012] One embodiment of the invention provides a method of making an electrochemical cell. The method includes introducing a cathode material into a cathode chamber of the electrochemical cell while the electrochemical cell is in a ground state; evacuating the cathode chamber and sealing the electrochemical cell from the external environment. Wherein the electrochemical cell further includes an anode chamber separated from the cathode chamber by its solid electrolyte and in ionic communication with the cathode chamber.

[0013] In one embodiment, the solid electrolyte defines a cathode compartment; the anode compartment is defined between the solid electrolyte and the housing of the electrochemical cell. In another embodiment, the solid electrolyte defines an anode compartment; the cathode compartment is defined between the solid electrolyte and the housing of the electrochemical cell.

Abstract

The invention relates to a method for manufacturing an electrochemical battery. The method comprises the following steps: feeding a negative electrode material into a cathode chamber of the electrochemical battery when the electrochemical battery is in a base state, vacuuming the cathode chamber, and sealing up the electrochemical battery so as to isolate the electrochemical battery from an external environment. The electrochemical battery further comprises an anode chamber which is isolated from the cathode chamber through electrolyte and is in ion communication with the cathode chamber.

Description

technical field [0001] The invention relates to a method for manufacturing an electrochemical battery, in particular to a method for manufacturing a rechargeable cell (Rechargeable Cell) or a secondary battery (Secondary Cell). Background technique [0002] Rechargeable batteries, also called secondary batteries, have been used for energy storage. Especially due to its high energy storage capacity, high energy density and long service life, rechargeable batteries, such as sodium metal halide batteries (Sodium Metal Halide Cell) are used for large-scale energy storage, For example, in electric vehicles. [0003] Typically, rechargeable batteries are designed with an anode chamber that can accommodate anode material and a cathode chamber that can accommodate cathode material. During charging and discharging of a rechargeable battery, the cathode material and the anode material are in ionic communication. However, in some cases, electrode materials often undergo volume chang...
