Background of Development: Addressing Growing Safety Concerns with Handy Fans
In recent years, the widespread use of lithium-ion batteries has led to a rise in fire and explosion incidents involving handy fans due to impacts from drops or exposure to high temperatures inside vehicles during summer. To provide not only cooling but also peace of mind, Ozma Corporation developed these new products, moving away from conventional ternary batteries to more stable lithium iron phosphate batteries and flame-resistant semi-solid-state lithium batteries.
Key Features: Uncompromised Safety “Preventing Thermal Runaway”
Lithium Iron Phosphate (LFP) Battery
Lithium iron phosphate batteries possess a robust crystal structure, making them highly stable and resistant to ignition or explosion, even under conditions of overcharging or external impact (such as nail penetration). Furthermore, these batteries do not utilize rare metals like cobalt, contributing to a lower environmental impact and positioning them as a sustainable choice for the next generation.
Semi-Solid-State Lithium-ion Battery
By transforming the electrolyte into a gel-like “semi-solid” state (approximately 3% liquid content), this battery prevents liquid leakage in the event of damage, further reducing the risk of fire. It also exhibits strong resistance to ignition or explosion from external impacts, including nail penetration.
