SK On, a Korean battery manufacturer, showcased its new fast-charging battery cells and various other products at InterBattery 2024, South Korea’s largest battery trade show.
The original SF (Super Fast) Battery, introduced in 2021, is a high-nickel battery that can be charged from 10 percent to 80 percent in just 18 minutes. The Advanced SF Battery is an upgraded version of the SF Battery, increasing the energy density by 9 percent while maintaining the same fast-charging time of 18 minutes. Higher energy density means that a battery can store a larger amount of energy, leading to further driving range on a single charge.
The SF+ Battery, another variant of the SF Battery, boasts a quicker charging time than the original: 15 minutes. SK On was able to reduce the transport distance of lithium ions while increasing their movement speed by applying high-capacity silicon with low-resistance graphite on the self-developed dual-layer structure.
At InterBattery 2024, SK On also showcases the Winter Pro LFP Battery underscoring its low-temperature performances. Compared to the existing conventional LFP, the Winter Pro LFP Battery extends the charging and discharging capacity by 16 percent and 10 percent, respectively, while increasing the energy density by 19 percent.
SK On is headquartered in Seoul, South Korea, and is a developer, manufacturer, and solutions provider of electric vehicle (EV) batteries with manufacturing sites in the U.S., Europe, and Asia. SK On is part of SK Group, South Korea’s second-largest conglomerate with major global companies in energy, semiconductors, and biopharmaceuticals.
