The new product was developed to provide consumers with peace of mind as the use of conventional lithium-ion (Li-ion) batteries has been restricted in places such as aircraft due to increased safety regulations following a series of explosion and fire incidents.

The LFP battery applied to the new product features a crystal structure characterized by an olivine structure where the hexagonal shapes are consolidated organically, maintaining a stable state.

Thanks to this, it does not emit oxygen even at high temperatures, thus reducing the risk of safety incidents due to overcharging or over-discharging. Additionally, the lack of oxygen inside the battery suppresses the phenomenon known as "thermal runaway."

Choi Se-hwan, CEO of SM Cell's battery division, noted, "We expect to play a game changer role in the continuously growing portable auxiliary battery market, and also significantly contribute to improving our performance."
