Abstract
A solvent-free lithium-ion battery (LIB) electrode production process is disclosed. The electrode production process employs polymeric binder materials that are distinct from the conventional polyvinylidene difluoride binders. A powder coating process can be used to manufacture the LIB electrodes. The powder coating process avoids the use of a solvent, which in turn reduces overall production costs and improves production worker safety.
Claims19
An apparatus, comprising:
- an electrode;
- and
- an active material powder-coated on a surface of the electrode, wherein the active material comprises:
- an electrochemically active component;
- and
- a binding compound for adhering the active material to the electrode, wherein the binding compound comprises polyimides, polyethyleneimines, polyesters, polyamides, polyurethanes, acrylics, polyolefins, polyvinylchloride, polystyrene, polyketones, copolymers thereof, and conjugated polymers, including n-type polymers and p-type polymers, or blends thereof.
