) provides one of the highest specific energy profiles available in mass production. The dominance of nickel drives up the energy density, while cobalt stabilizes the layered atomic structure during cycling. Aluminum acts as a stabilizing modifier, mitigating thermal runaway risks and widening the safe operational window. Anode Technology
Ensure the operating environment remains between 15°C and 25°C whenever possible. 5. Applications and Use Cases
