Question

Accepted Answer

Ammonium Phosphate Is the Key Chemical in the New Portable Battery Fire Containment Device

The newly developed portable device for the safe storage, collection, transport, and disposal of lithium-ion batteries utilises ammonium phosphate. This chemical is the same substance commonly found in standard fire extinguishers, indicating a reliance on established fire suppression technology. The device is designed to contain fires originating from lithium-ion batteries, preventing the spread of heat and flames.
Functionality and Chemical Composition

The core of the portable device's safety mechanism lies in its containment of ammonium phosphate. This chemical agent is widely recognised for its effectiveness in extinguishing fires, particularly those involving flammable materials. When a lithium-ion battery ignites within the device, the ammonium phosphate acts to suppress the fire, isolating the incident and preventing external escalation.
Addressing the Rise in Battery Fires

This innovation emerges in response to an increasing number of fires linked to lithium-ion batteries in Japan. Incidents involving portable power banks igniting in public spaces have become more frequent in recent years, prompting a demand for enhanced safety measures. The device aims to provide a secure solution for managing these volatile components throughout their lifecycle, from storage to disposal.
Safe Handling and Disposal Concerns

Lithium-ion batteries, prevalent in devices such as mobile power banks and portable energy stations, pose a fire risk if they overheat. Factors like physical impact, direct sun exposure, or excessive heat during charging can trigger thermal runaway. While regulations exist for their collection, a significant number are improperly disposed of as general waste. This improper disposal has led to numerous reports of fires occurring in waste collection vehicles and at disposal facilities.
Validation and Commercialisation Plans

The research team has conducted experiments to validate the device's efficacy, collaborating with fire authorities, local governments, and transportation companies. These trials are crucial in preparing for the device's commercial rollout, which is targeted for April. The development underscores the importance of establishing secure protocols for handling and disposing of lithium-ion batteries, acknowledging that not all consumers adhere to proper disposal practices.
