Claims10
A method for manufacturing a lithium battery electrode comprising the steps of:
- depositing an electrode ink on a current collector made of carbon fibers by coating or printing;
- said ink comprising at least one active electrode material, at least one polymer hinder, at least one electronic conductor;
- drying:
- evaporating the solvent;
- the current collector being porous and made of woven or nonwoven carbon fibers;
- the polymer binder of the ink being poly(acrylic acid) having a molecular weight ranging between 1 000 000 and 2 500 000 g.mol−1.
