Abstract

A pre-lithiated lithium ion battery cell is disclosed that includes a sacrificial lithium-containing material on a negative electrode, a positive electrode, and a positive electrode, the sacrificial lithium-containing material being configured to respond to a first application of a charge to the battery cell, Charge current and decompose to release lithium ions to promote the formation of a solid electrolyte interface via reaction of lithium ions on the surface of the negative electrode adjacent to the positive electrode.

Description

technical field [0001] The present disclosure relates to lithium-ion battery cells and processes for making the lithium-ion battery cells. Background technique [0002] Lithium-ion batteries present a rechargeable electrochemical storage technology. Due to the electrochemical potential and theoretical capacity offered by lithium-ion batteries, the technology shows promise for the electrification of the drivetrain and for providing stationary storage solutions to enable the efficient use of renewable energy sources. Lithium-ion batteries generate electricity by means of a positive electrode, a negative electrode, and an electrolyte that connects and separates the two electrodes. Lithium ions migrate from one electrode to the other via the electrolyte, while the associated electrons are collected by the current collector and can be used as an energy source for electronic devices. However, when charging current is first applied to the battery, a solid electrolyte interface (S...
