Three-dimensional architected pyrolyzed electrodes for use in secondary batteries and methods of making three-dimensional architected electrodes

摘要

In an aspect, an electrode for an electrochemical cell comprises: a structure having a nano- or micro-architected three-dimensional geometry; said structure comprising one or more active carbon allotrope materials; wherein said structure is characterized by an average density less than or equal to 2.3 g cm⁻³ and an average specific strength (strength-to-density ratio) greater than or equal to 0.004 GPa g⁻¹ cm³. Also disclosed herein are methods for making an electrode for an electrochemical cell, and methods for making an electrochemical cell.
