Abstract
The present disclosure relates to a lithium-ion battery component and methods for manufacturing the lithium-ion battery component. The battery component, in some examples, includes a current collector, a porous deposit of first active material and first binder on the current collector, and a solvent-free electrode layer of second active material and second binder laminated with the porous deposit to at least partially occupy the pores of the porous deposit.
Claims20
A lithium-ion battery component comprising:
- a current collector;
- a porous deposit of first active material and first binder on the current collector;
- and
- a solvent-free electrode layer of second active material and second binder laminated with the porous deposit to at least partially occupy pores of the porous deposit.
1 more element
A method of manufacturing an electrode comprising:
- applying an electrode slurry of a first active material, a first binder, a first conductive additive, and a solvent onto a current collector;
- drying the electrode slurry to evaporate the solvent and form a first electrode layer on the current collector;
- applying an electrode mixture of a second active material, a second binder, and a second conductive additive onto the first electrode layer by a solvent-free dry coating process such that a second electrode layer forms on the first electrode layer;
- and
- compressing the second electrode layer with the first electrode layer to form an electrode.
2 more elements
A lithium-ion battery comprising:
- a current collector;
- and
- a pair of electrodes with the current collector disposed between the electrodes, wherein at least one of the electrodes has a porous deposit of first active material and first binder on the current collector, and wherein the porous deposit is configured to provide interfacial adhesion between the current collector and a solvent-free electrode layer, of second active material and second binder, laminated with the porous deposit to at least partially occupy pores of the porous deposit.
