Geely Strengthens its Battery Presence with New Aegis Generation Blade Cells
Geely is determined to take control of the production of batteries for its electric vehicles to reduce its dependence on suppliers like CATL or FinDreams (BYD). After the Zeekr 007 and its Golden Battery, the new Geely Galaxy E5 SUV adopts a new family of batteries from the Chinese group, called Aegis.
The blade format of these batteries is similar to BYD’s design, but Geely emphasizes the energy density of its new offering, which reduces the size of battery packs for more compact models compared to the 007 sedan, for example. The announced density is 192 Wh/kg, similar to that of traditional NMC batteries. The key difference is that Aegis batteries are LFP chemistry, making them more cost-effective.
One significant difference compared to BYD’s “Blade” is that Geely’s Aegis measures only 580 mm in length, while BYD’s are 960 mm. Geely also highlights faster charging, averaging 2.45 C for 10-80% compared to 1.61 C for its rival. Additionally, Geely emphasizes a longer lifespan of over 3500 cycles and the preservation of capacity when exposed to cold temperatures (90.46% capacity retained at -30°C).
Geely showcases the safety of these batteries with various torture tests, such as exposure to fire for 130 seconds at over 1000 degrees, 48-hour water immersion, puncturing, and crushing by a roller compactor, without causing any fires.
Initially used in the E5, these new in-house batteries will eventually equip other Geely group models, including Smart, Volvo, Zeekr, and Lynk & Co.
