NEGATIVE ELECTRODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240120484 titled 'NEGATIVE ELECTRODE

Simplified Explanation

The negative electrode in this patent application has a specific composition to prevent an increase in battery resistance when exposed to high temperatures for extended periods. The negative electrode includes a current collector and an active material layer containing a trace component of Ti, Si, Ca, or Cr in a specific concentration range.

• The negative electrode paste used in manufacturing has the right viscosity to ensure proper electrode formation.
• The negative electrode active material layer contains a trace component of Ti, Si, Ca, or Cr in a concentration range of 10-800 mass ppm.
• The trace component helps prevent an increase in battery resistance when exposed to high temperatures for a long time.

Potential Applications

This technology could be applied in the manufacturing of lithium-ion batteries for electric vehicles, portable electronics, and energy storage systems.

Problems Solved

This technology addresses the issue of increased battery resistance when subjected to high temperatures for extended periods, which can lead to reduced battery performance and lifespan.
