A positive electrode for an energy storage device includes a first activated carbon material comprising pores having a size of ≤ 1 nm, which provide a combined pore volume of > 0.3 cm3/g, pores having a size of > 1 nm to ≤ 2 nm, which provide a combined pore volume of ≥ 0.05 cm3/g, and < 0.15 cm3/g combined pore volume of any pores having a size of > 2 nm. A negative electrode for the energy storage device includes a second activated carbon material comprising pores having a size of ≤ 1 nm, which provide a combined pore volume of ≤ 0.3 cm3/g, pores having a size of > 1 nm to ≤ 2 nm, which provide a combined pore volume of ≥ 0.05 cm3/g, and < 0.15 cm3/g combined pore volume of any pores having a size of > 2 nm. The total oxygen content in at least the first activated carbon material is at most 1.5 wt.%. |
