Battery manufacturer EVE Energy has launched its Omnicell 6C fast-charging large cylindrical all-purpose battery specifically designed for high-end passenger cars. The new battery has four key highlights: fast charging, low temperature, physical, and a sustainable life cycle. It can charge from 10% to 80% in 9 minutes at a 25°C temperature, achieving a driving range of 300 km after only 5 minutes, while in a low temperature environment of -30°C, charging from 10% to 80% takes only 25 minutes.
“The difficulty in reaching 6C, the C being the measure of battery discharge relative to the battery’s maximum capacity, is to reduce internal resistance while improving cooling efficiency. Speeding up the heat exchange while maintaining a low internal battery resistance ensures the battery runs at an optimal temperature.”
Johnson Feng, product director of the EVE Energy Battery System Research Institute
Internal resistance reduction: Technical innovations have been made in electrolyte, separator, and other materials in the battery cell, reducing the internal resistance of the battery cell to 1.4mΩ, which translates to a 20% internal resistance reduction for 10 minutes of fast charging.
Heat exchange acceleration: Omnicell adopts a three-sided heat dissipation design on the top and both sides of each cell to better control the temperature of the battery cell and further solve the high-voltage current plate heating issue of the battery, allowing the entire battery to maintain a suitable temperature with a heat exchange area to reach 52.3 mm²/Wh, increasing the heat exchange efficiency by 270% when fast charging.
Meanwhile, the Omnicell boasts sustainable advantages that significantly reduce carbon footprint with extended battery life.
High residual value: Using NCM materials, Omnicell achieves 10% higher residual value than lithium iron phosphate batteries, and the cylindrical design ensures standardized disassembly and easier recycling. The EVE Energy’s cylindrical cell production line uses 100% green electricity in the manufacturing of anode, cathode, and cell, and 50% secondary NCM materials, complying with the latest EU battery laws.
EVE Energy has also successively launched electric vertical take-off and landing (eVTOL) batteries and accelerated the R&D of solid-state batteries.
Electric Take-Off and Landing (eVTOL) batteries: EVE Energy’s eVTOL battery has an energy density of 320Wh/Kg that can be quickly charged to 80% within 10 minutes, meets 10C high output capacity during the life cycle, and guarantees more than 7,000 cycles, injecting new impetus into the rapidly emerging low-altitude economy.
Solid-state batteries: Eve Energy plans to launch high-power, high environmental tolerance, and safe all-solid-state batteries in 2026, and gradually promote 400 Wh/kg all-solid-state batteries by 2028.
