Battery Apparatus with Negative-Catalyst Fire Extinguishing Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery apparatuses require an excessive amount of time for fire extinguishment by fireproofing members when battery cells ignite due to inappropriate handling, allowing potential spread of fire to other cells and the casing.
Innovation Solution
Incorporating a fire-extinguishing agent with a negative-catalyst effect, such as components that absorb combustion gases or inhibit oxidation, within the battery apparatus casing to rapidly extinguish fires and prevent their spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fireproofing members are used to extinguish fires in battery cells, then the battery apparatus has fire protection capability, but the fire extinguishment time is excessive and fire may spread to other cells and casing
Solution Approach 1:
The patent changes the chemical parameters of the fire-extinguishing agent by introducing a negative-catalyst component that accelerates the decomposition of peroxides and generates free radicals. This catalytic effect dramatically increases the reaction rate and fire extinguishment speed, reducing the extinguishment time from a prolonged period to a rapid response while maintaining reliable fire protection capability.
Solution Approach 2:
The fire-extinguishing agent is formulated as a composite material containing multiple components: peroxide compounds (for oxygen supply), phosphorus compounds (for chain reaction inhibition), and negative-catalyst components (for accelerated decomposition). This composite structure enables rapid fire extinguishment while preventing fire spread to other battery cells and the casing, thus improving both response time and overall fire protection reliability.
2Productivity
If high energy density battery cells are used to increase power output, then the productivity and power supply capability improve, but the risk of fire spread and severity of combustion increase
Solution Approach 1:
The fire-extinguishing agent acts as an intermediary substance between the battery cells and the fire hazard. It is pre-positioned within the battery apparatus structure (in grooves or channels between cells) and serves as a mediating barrier that can rapidly intervene to stop combustion propagation. This intermediary approach allows high energy density cells to be used for improved productivity while the fire-extinguishing agent mediates the fire spread risk by providing rapid local suppression.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively and rapidly extinguishes fires in battery cells, inhibiting the spread to other cells and the casing, even when cells are highly charged or have high energy density, and protects the fire-extinguishing agents from impact.
Implementation Method 1
a fire-extinguishing agent or fire-extinguishing agents, which include(s) a component that provides a negative-catalyst effect with respect to combustion

AI summary
A battery apparatus may include: one or more battery cells; one or more fire-extinguishing agents, which include(s) a component that provides a negative-catalyst effect with respect to combustion; and a casing, which houses the battery cell(s) and the fire-extinguishing agent(s). In the event that one or more of the battery cell(s) has (have) been subject to inappropriate handling and consequently has (have) ignited, the fire can be rapidly extinguished by the negative-catalyst effect of the fire-extinguishing agent(s). In addition, if one or more of the battery cell(s) of the battery apparatus has (have) ignited, because the fire can be rapidly extinguished, spreading of the fire to other battery cells, the casing, etc. can be inhibited.
