Anode For A Cell Of A Lithium Ion Battery, Its Manufacturing Process And The Battery Incorporating It

Abstract: The invention relates to an anode usable in a cell of a lithium-ion battery comprising an electrolyte based on a lithium salt and a non-aqueous solvent, to a process for manufacturing this anode and to a lithiumion battery having one or more cells incorporating this anode. This anode is based on a polymer. composition, obtained by melt processing and without solvent evaporation, that is the product of a hot compounding reaction between an active material and additives comprising a polymer binder and an electrically conductive filler. According to the invention, the binder is based on at least one crosslinked elastomer and the additives furthermore comprise at least one non-volatile organic compound usable in the electrolyte solvent, the composition advantageously comprising said active material in a mass fraction greater than or equal to 85%.

Specification

ANODE FOR A CELL OF A LITHIUM-ION BATTERY, ITS MANUFACTURING PROCESS AND THE BATTERY INCORPORATING IT 5 The present invention relates to an anode that can be used in a cell of a lithium-ion battery, to a process for manufacturing this anode, and to a lithiumion battery having one or more cells incorporating this anode. 10 There are two main types of lithium storage battery: lithium-metal batteries, where the negative electrode is made of lithium metal (which material causes problems with safety when in the presence of a liquid electrolyte), and lithium-ion batteries, where 15 the lithium remains in the ionic state. Lithium-ion batteries consist of at least two conductive Coulombic electrodes of different polarities, the negative electrode or anode and the positive electrode or cathode, between which electrodes 20 a separator is located, which separator consists of an electrical insulator imbibed with an aprotic electrolyte based on ~ i +ca tions ensuring the ionic conductivity. The electrolytes used in these lithiumion batteries usually consist of a lithium salt, for 25 example of formula LiPF6, LiAsF6, LiCF3S03 or LiC104, which is dissolved in a mixture of non-aqueous solvents such as acetonitrile, tetrahydrof uran, or more of ten a carbonate, for example of ethylene or propylene. The active material of the anode of a lithium-ion 30 battery is typically graphite (capacity of 370 mAh/g and redox potential of 0.05 V relative to the ~ i + / ~ i couple) or, as a variant, mixed metal oxides, among which are included the lithiated titanium oxides of formula Li4Ti5OI,2 LiXTiO2, or even compounds, for 35 example, of formula LixCuV04, LixSn02, LixMo02, Li,MoS2, where 0
