Title:
Ｌｉイオン電池に使用するためのセルロース系自立型フィルム
Document Type and Number:
Japanese Patent JP7431175
Kind Code:
B2
Abstract:
The present technology relates to self-standing electrodes, their use in electrochemical cells, and their production processes using a water-based filtration process. For example, the self-standing electrodes may be used in lithium-ion batteries (LIBs). Particularly, the self-standing electrodes comprise a first electronically conductive material serving as a current collector, the surface of the first electronically conductive material being grafted with a hydrophilic group, a binder comprising cellulose fibres, an electrochemically active material, and optionally a second electronically conductive material. A process for the preparation of the self-standing electrodes is also described.
