The ever-growing demand for advanced rechargeable lithium-ion batteries in portable electronics and electric vehicles has spurred intensive research efforts over the past decade. The key to sustaining the progress in Li-ion batteries lies in the quest for safe, low-cost positive electrode (cathode) materials
High surface area, good electrical conductivity, and low weight. Aluminum foil is used as a cathode current collector for Lithium-ion batteries. It is a critical component in the construction of the battery, as it helps to conduct electricity and acts as a barrier to prevent the electrolyte from leaking.
It is suggested to use aluminum foil as a convenient material and the general approach can be employed as a methodological technique for accelerated composition of an acceptable electrolyte formula for electrodes containing other elements forming alloys with lithium (in particular, silicon and tin).
The β-LiAl on Al foil bilayer electrode (β-LiAl as active material, Al as current collector) was prepared by an electrochemical prelithiation on Al foil in Al//Li half cells using the CA technique. Firstly, the half cell was held at 400 mV versus Li/Li + for 4 h to largely isolate the irreversible surface reactions.
(a) SEM image taken for a partially lithiated Al foil using a 90° sample holder with a tilting angle of 45°, of which the cross-section is enlarged in (b) at a magnitude of 200×. The macroscopic views of the electrode surface and the backside are also shown.
The electrochemical performance and stability of the cell with the Al–In foil negative electrode approaches those of a cell with a pure indium foil negative electrode with a similar thickness (Supplementary Fig. 2), which exhibited an initial CE of 86% and stable cycling for hundreds of cycles.
To circumvent this issue, here we report the use of non-pre-lithiated aluminum-foil-based negative electrodes with engineered microstructures in an all-solid-state Li-ion cell configuration.
