The Chinese holding company Geely shared details about the Aegis cells: advanced batteries that were distinguished by energy density, overall dimensions, charging speed and endurance at low temperatures. The resource is also impressive: the declared service life is 3,500 cycles, which corresponds to a mileage of over a million kilometers.
The lithium-iron-phosphate battery of Geely Aegis is 40% shorter than a traditional battery, which allows to reduce internal resistance and heat generation. Also, compact dimensions allow more rational use of space. The energy density is 192 Wh per kilogram, which is a very good indicator.
Geely claims that the new cells degrade minimally, which will reduce carbon emissions by 80,000 tons per year. There is no explanation of how the calculation was made. But it is promised that charging from 10 to 80% will take 17 minutes, which is almost one and a half times faster than charging ordinary batteries. At -30°C, Aegis cells lose only 9.46% of their capacity, while current batteries retain only 78.96% of their capacity in such frost.
Geely's batteries have passed stress tests: immersion in seawater, a load of 26 tons, burnout by fire, side impact and cold tests. For all parameters, better values were achieved than those stipulated by the national standard of China. And most importantly, ordinary buyers will soon be able to test the battery: the Galaxy E5 crossover will be the first to receive Aegis cells.
