Abstract Disclosed herein are negative active material compositions, comprising: a carbonaceous material (6') having a surface area of at least 250 m2/g; and an organic molecule expander (4'), wherein the ratio of carbonaceous material to expander ranges from 5:1 to 1:1, and wherein the composition has a median pore size ranging from 0.8 μι to 4 μm. Also disclosed are electrodes and batteries comprising such compositions, and methods of making thereof. La présente invention se rapporte à des compositions de matériau actif négatif qui comportent : un matériau carboné (6') qui présente une superficie d'au moins 250 m2/g; et un dispositif d'expansion de molécule organique (4'), le rapport entre le matériau carboné et le dispositif d'expansion variant entre 5:1 et 1:1 et la composition présentant une dimension de pore moyenne qui varie entre 0,8 μm et 4 μm. La présente invention se rapporte également à des électrodes et à des batteries qui comportent de telles compositions ainsi qu'à des procédés de fabrication de ces dernières.
