Abstract
The present disclosure describes energy storage (e.g., electrochemical) devices with customized architectures. Such customized architectures include multilayered electrode films and/or multidimensional electrode films.
Claims20
A multilayer electrode film comprising:
- a first electrode film layer comprising a first interface surface and a second interface surface, a first binder and a first binder concentration, and a first active material and a first active material concentration;
- and
- an exterior electrode film layer comprising a third interface surface and a fourth interface surface, an exterior binder and an exterior binder concentration, and an exterior active material and an exterior active material concentration;
- wherein the first binder concentration is greater than the exterior binder concentration;
- wherein the exterior active material concentration is greater than the first active material concentration;
- wherein the first and second interface surfaces are disposed over the third and fourth interface surfaces;
- and
- wherein at least one of the first and exterior binders is an electron beam polymerized binder.
