AI Technical Summary
Existing oxygen candles cannot burn stably and continuously in ultra-low temperature environments, and there are potential safety risks due to heat accumulation caused by fuel.
Employing a fuel-free design, this invention utilizes highly thermally conductive carbon-based nanomaterials such as graphene, carbon nanotubes, or nanographite, combined with catalysts such as nano-iron oxide, cobalt, nickel, or manganese, to prepare a fuel-free low-temperature oxygen candle oxygen-generating core. The heat conduction path is formed through thermally conductive materials, ensuring stable combustion of the core at -50°C.
It achieves continuous and stable combustion at -50℃, with an oxygen production rate of over 98.5% and a wall surface temperature below 135℃, avoiding chlorine generation and improving safety and reliability.
