An electrode for a lithium ion battery includes a matrix based on at least one polysaccharide and also particles of at least one electrochemically active material which are embedded in the matrix, with the electrode being free of synthetic polymeric compounds. A battery contains the electrode and a polysaccharide is a binder for electrochemically active electrode materials for such an electrode.

Electrodes and lithium-ion cells with a novel electrode binder

The present invention is related to an electrode and a method for preparing the same, and is particularly related to an electrode that has an intricate structure of active material layer, conductive material layer, or mixture layer of active material and conductive material that displays superior electrochemical properties despite being thin, and a method for preparing an electrode using the coating method of SIC.

Electrode and method for preparing the same using substrate induced coagulation (SIC)

A secondary battery is comprised of a positive electrode, a negative electrode formed from a lithium storage material, and a non-aqueous electrolyte. The non-aqueous electrolyte includes a lithium salt, non-aqueous aprotic solvent(s), such as ethylen carbonate, propylene carbonate, dimethyl carbonate, ethymethyl carbonate and diethyl carbonate, and a small percentage of at least one organic additive. The negative electrode may comprise a carbon such as graphite, and the positive electrode may comprise a lithiated metal oxide or phosphate, such as LiCoO, LiNiO, LiMnO, LiFePO, or mixtures thereof. The organic additives have one or more unsaturated bonds activated with respect to oxidation by electron-pushing alkyl groups. They are in most cases known to be able to undergo polymerization reactions, such as an anodically induced polymerization especially under certain conditions. The additives are oxidized at the cathode at a potential of more than 4.3 V vs. Li/Li. With these additives in amounts of 0.001 to 10%, a passivation layer is formed on the cathodes, and the sensitiveness of the battery against overcharge is reduced. The electrolyte mixtures do not deteriorate the properties of the battery anodes.
