Hierarchical 3D Mixed Conducting Networks

Hierarchical 3D mixed conducting network consists of transport channels for both electrons and Li ions, which has shown an exceeding electrochemical performance compared with other electrode materials through enhancing the electronic conductivity of the material. 

Bearing in mind that nanoporous carbon itself is already a mixed conducting 3D network, we propose and realize an alternative optimized nanostructure design of electrode materials for high-power and high-energy lithium batteries by combining

In the context of constructing hierarchical 3D mixed conducting networks, another approach is the introduction of 3D carbon nanotube (CNT) networks into active materials, such as CuO-CNTs composite. Through a simple solution method, self-assembled CuO and CuO-CNTs nanomicrospheres with an average size of 2.5 pm can be easily synthesized. It has been demonstrated that the as-formed CuO-CNTs nanomicrospheres contain uniformly distributed CNTs [68]. Furthermore, electrochemical experiments have confirmed that these composite spheres exhibit a superior cycling performance (good retention of capacity on cycling] and 

Considering all the merits that the hierarchical 3D mixed conducting networks have, such as negligible diffusion times, much enhanced local conductivities, and possibly faster transfer reactions, such networks can provide excellent power performance, thus making them especially suitable for EVs and HEVs [14],
