Abstract
Disclosed herein is an apparatus comprising an electrode active layer comprising a network of high aspect ratio carbon elements defining void spaces within the network; a plurality of electrode active material particles disposed in the void spaces within the network and enmeshed in the network; and a surface treatment on the surface of the high aspect ratio carbon elements which promotes adhesion between the high aspect ratio carbon elements and the active material particles.
Claims21
An energy storage apparatus comprising:
- an electrode active layer in the energy storage apparatus, comprising:
- a network of high aspect ratio carbon elements defining void spaces within the network;
- a plurality of electrode active material particles disposed in the void spaces within the network and enmeshed in the network;
