NEGATIVE ELECTRODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18389965 titled 'NEGATIVE ELECTRODE

Simplified Explanation

The negative electrode in this patent application contains a trace component made up of Ti, Si, Ca, or Cr, with a content between 10 and 800 mass ppm in relation to the negative electrode active material. This trace component helps prevent an increase in resistance of a battery when exposed to high temperatures for extended periods.

  • The negative electrode paste has an appropriate viscosity during manufacture.
  • The negative electrode active material layer contains a trace component of Ti, Si, Ca, or Cr.
  • The trace component content is between 10 and 800 mass ppm.
  • The trace component helps prevent resistance increase in the battery at high temperatures.

Potential Applications

The technology could be applied in the manufacturing of batteries for various electronic devices, electric vehicles, and energy storage systems.

Problems Solved

The technology addresses the issue of increased resistance in batteries when subjected to high temperatures for prolonged periods, which can lead to decreased performance and lifespan.

Benefits

The negative electrode with the trace component helps maintain battery performance and longevity even under harsh conditions, improving overall reliability.

Potential Commercial Applications

The technology could be utilized by battery manufacturers looking to enhance the quality and durability of their products, especially in applications where batteries are exposed to high temperatures.

Possible Prior Art

One possible prior art could be the use of different additives in battery electrodes to improve performance and stability, but the specific combination of Ti, Si, Ca, or Cr as trace components in the negative electrode active material layer may be novel.

=== What is the specific composition of the negative electrode paste mentioned in the patent application? The specific composition of the negative electrode paste is not detailed in the abstract. It would be interesting to know the exact materials and proportions used to achieve the desired viscosity and performance.

=== How does the trace component (Ti, Si, Ca, or Cr) interact with the negative electrode active material to prevent resistance increase in the battery? The mechanism by which the trace component interacts with the negative electrode active material to prevent resistance increase is not explained in the abstract. Understanding this interaction could provide insights into the effectiveness of the innovation.
