Abstract (en)
[origin: WO2019073160A1] The invention relates to an electrode composition for lithium-ion battery, a process for preparing the composition, such an electrode and a lithium-ion battery incorporating same. The composition comprises an active substance able to perform reversible insertion/deinsertion of lithium in the electrode, an electrically conductive filler and a polymeric binder comprising at least one modified polyolefin, and it is such that the modified polyolefin (If1) is derived from a nonpolar aliphatic polyolefin and incorporates oxygenated CO and OH groups, having a content by weight of oxygen atoms of between 2% and 10% inclusive. The modified polyolefin may be the product of a controlled thermal oxidation reaction, under an atmosphere comprising oxygen and at a temperature of between 200°C and 300°C, of the nonpolar aliphatic polyolefin with oxygen.
