Lifestyle Brand “String” Launches “Mobile Fireproof Pouch” to Address Lithium-ion Battery Fire Risks

Gadgets

Development Background

Lithium-ion batteries are widely used in everyday electronic devices such as smartphones and mobile batteries. However, these batteries carry the risk of thermal runaway and ignition due to damage or abnormal heat generation. With increasing opportunities to store and charge multiple gadgets both at home and on the go, the importance of preparing for potential fires has grown. GROOVE Inc. developed this product to integrate disaster prevention features into the routine act of “storing” for individuals who carry lithium-ion battery-powered devices.

Mobile Fireproof Pouch Features

  1. Built-in Fire Extinguishing Film
    The pouch contains a fire extinguishing film. In the event of an abnormal temperature rise from a stored gadget, it supports initial fire suppression and prevents the fire from spreading.

  2. Everyday Gadget Storage Pouch
    Designed not just as an emergency item, but as an everyday storage pouch for mobile batteries and other frequently used gadgets. This approach embodies the “Phase-Free” concept, integrating safety measures into daily items rather than requiring separate disaster preparedness goods.
