AI Technical Summary
Lithium titanium oxide (LTO) negative electrodes suffer from low electrical conductivity, hindering the commercialization of next-generation batteries, and there is a need for improved stability against internal short-circuits.
A negative electrode structure with a first layer containing a carbonaceous or silicon-based active material and a second layer comprising lithium titanium oxide (LTO) and single-walled carbon nanotubes (SWCNTs), where the LTO layer has a loading amount of 0.1 mAh/cm² or less, ensuring improved electrical conductivity and stability.
The electrode structure enhances electrochemical performance, charge/discharge efficiency, and stability against internal short-circuits by utilizing SWCNTs to improve conductivity, even with a minimal LTO layer.
