At the IAA Transportation 2024 in Hannover, Germany, Samsung SDI announced its latest lithium-iron phosphate battery, dubbed LFP-plus. This new battery boasts a 10% increase in energy density compared to its previous LFP offerings. While the exact energy density figure has not been disclosed, it’s estimated to be around 180 watt-hours per kilogram.

One of the standout features of the LFP-plus battery is its rapid charging capability. Using the latest charging technologies, it can be charged to 80% in just 20 minutes. Additionally, the battery offers a significantly longer lifespan.

Samsung SDI has also enhanced the battery’s safety by implementing advanced technologies to prevent thermal runaway, a condition where a battery cell overheats and can potentially lead to fire.

The LFP-plus battery utilizes lithium iron phosphate (LiFePO4) as its cathode material and graphite with a metal foil as its anode material. This combination makes it more stable than other lithium-ion batteries and less prone to catching fire. Furthermore, it offers an exceptionally long cycle life, exceeding 2,000 charge cycles. However, LFP batteries generally have a lower energy density compared to other lithium-ion chemistries like NMC (nickel manganese cobalt).

LFP batteries are often favored by automakers due to their balance of safety, long lifespan, efficiency, and cost. The LFP-plus battery, with its improved performance and longevity, could become an even more attractive option. Although the development of the LFP-plus battery is complete, a mass production timeline has not yet been announced.
