NOVELTY - An electrode comprises a current collector and an electrode layer coated on one or more surfaces of the current collector, where the electrode layer included an electrode active material, a binder and an additive comprising oxolane-containing compound (I). USE - Electrode used for secondary battery (claimed) e.g. lithium-ion battery for electric vehicles. ADVANTAGE - The electrode has excellent electrochemical performance. DETAILED DESCRIPTION - An electrode comprises a current collector and an electrode layer coated on one or more surfaces of the current collector, where the electrode layer included an electrode active material, a binder and an additive comprising oxolane-containing compound of formula (I). n = 5-25;and w+x+y+z = 10-80. An INDEPENDENT CLAIM is included for electrode slurry, which comprises the electrode active material, the binder, the additive comprising the compound (I), and the solvent. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating preparation of the electrode. Preparation of the electrode (100) Dispersing binder and additive in solvent (101) Adding conductive agent (102) Dispersing electrode active material (103) Applying homogenized slurry (104)
