Title:
DISTRIBUTED CELL FORMATION SYSTEMS AND PRE-LITHIATION MODULES FOR LITHIUM CONTAINING SECONDARY BATTERIES
Abstract:
A pre-lithiation module for a lithium containing secondary battery includes a switched capacitor circuit, a pre-lithiation module controller connected to the switched capacitor circuit, a battery connector for electrical connection to an electrode busbar and a counter-electrode busbar of the lithium containing secondary battery, and a pre-lithiation connector for electrical connection to an auxiliary electrode of the lithium containing secondary battery. The pre-lithiation module controller includes a processor and a memory. The memory of the pre-lithiation module controller stores instructions that program the pre-lithiation module controller to operate the switched capacitor circuit to selectively conduct a current through the auxiliary electrode to diffuse lithium to electrode active material layers of the lithium containing secondary battery.

Titles:
Polymer protective film and metal lithium negative electrode, lithium secondary battery and vehicle
聚合物保护膜及金属锂负极、锂二次电池及车辆
Abstracts:
The application discloses a polymer protective film, a metal lithium negative electrode, a lithium secondary battery, and a vehicle. The structural formula of the polymer protective film is as follows: The polymer protective film disclosed in the present application has good binding force with metal lithium and good ion Conductivity, and then effectively block the contact between metal lithium and electrolyte, while ensuring the effective conduction of lithium ions, making lithium ions evenly distributed, avoiding the generation of lithium dendrites, and also helping to reduce the interface between the polymer and metal lithium Impedance, improve the cycle performance of the battery.
Title:
TEXTURED METAL SUBSTRATES FOR NEGATIVE ELECTRODES OF LITHIUM METAL BATTERIES AND METHODS OF MAKING THE SAME
Abstract:
A lithium metal negative electrode for an electrochemical cell for a secondary lithium metal battery includes a polycrystalline metal substrate having a major facing surface with a defined crystallographic texture. An epitaxial lithium metal layer is formed on the major facing surface of the polycrystalline metal substrate. The epitaxial lithium metal layer exhibits a predominant crystal orientation. The predominant crystal orientation of the epitaxial lithium metal layer is derived from the defined crystallographic texture of the major facing surface of the polycrystalline metal substrate.
