A fluorine-free, water-processable binder of polyacrylic acid and carboxymethyl cellulose crosslinked by citric acid enables LiFePO4 electrodes to match initial capacity and improve cycle stability versus PVDF.
- Why it matters: Battery making currently depends on PVDF and N-methyl-2-pyrrolidone, raising cost and limiting sustainability, while bio-based aqueous binders often lack sufficient mechanical strength and electrochemical stability.
- What they did: The authors built a mixed bonding network (hydrogen, covalent, and ionic) to enhance adhesion and oxidative and thermal stability, then tested LiFePO4 positive electrodes and extended the chemistry across electrode materials.
- The result: In direct recycling of spent positive and negative electrodes, the fluorine-free binder supports full recovery to reach the same performance as pristine materials without fluorinated residue, with life-cycle analysis showing reduced energy cost and emissions versus PVDF recycling.
