AI Technical Summary

Technical Problem

Existing analytical methods for battery gases can only analyze gas temporarily retained in a chamber and fail to capture gases continuously emitted over time.

Method used

An analytical method involving a flow path around a battery to introduce gases emitted over time directly into a gas analyzer, allowing for continuous analysis without temporary storage, and optionally using filters, negative pressure devices, and heaters to enhance accuracy and reliability.

Benefits of technology

Enables easy and continuous analysis of gas emissions from batteries over time, improving analytical accuracy and reducing costs by eliminating the need for temporary storage and transport of gases, suitable for analyzing large objects like battery modules and products under actual usage conditions.

Abstract

To provide an analysis method facilitating temporal analysis of gas emitted from a battery.SOLUTION: An analysis method for a solid object includes the steps of: arranging a flow path for introducing gas around a battery; inducing an abnormality in the battery with the arranged flow path; introducing gas emitted from the battery in which the abnormality occurred into the flow path over time; and analyzing the gas introduced into the flow path using a gas analyzer.SELECTED DRAWING: Figure 1
