Extreme temperatures – Very long cycle life
Safety and robustness
Hybrid supercapacitor cells combine the energy density of lithium-ion cells and supercapacitors but without safety risks, offer a much longer cycle-life while operating in extreme temperatures and power ranges.
They mainly exist in energy-type cells and power-type cells. Explore them first on the overview page and in detail in the datasheets.
Altreonic-Kurt.energy has tested them all, often including stress and abuse tests.

Wide temperature range – long cycle life
Safety and robustness
Sodium-ion cells offer a similar density like LFP lithium-ion cells but or more cost-efficient, have a wider operating temperature, wider DoD and longer cycle life. However, they score much better for sustainability and recyclability as no Lithium, Nickel or Cobalt is needed. They excel in safety just like our selected hybrid supsercapacitors.
