摘要： An electrode for an electrochemical device includes porous carbon particles. In a pore distribution of the porous carbon particles, a ratio B/A of an integrated volume B to an integrated volume A ranges from 1 to 1.5, inclusive. The integrated volume A is an integrated volume of pores each having a pore diameter of more than or equal to 1 nm and less than 2 nm. The integrated volume B is an integrated volume of pores each having a pore diameter of more than or equal to 2 nm and less than or equal to 50 nm. A volume-based particle diameter frequency distribution of the porous carbon particles has a first peak and a second peak. A particle diameter corresponding to the second peak is larger than a particle diameter corresponding to the first peak.

摘要： A printed energy storage device includes a first electrode, a second electrode, and a separator between the first and the second electrode. At least one of the first electrode, the second electrode, and the separator includes frustules, for example of diatoms. The frustules may have a uniform or substantially uniform property or attribute such as shape, dimension, and/or porosity. A property or attribute of the frustules can also be modified by applying or forming a surface modifying structure and/or material to a surface of the frustules. A membrane for an energy storage device includes frustules. An ink for a printed film includes frustules.
