Beschreibung
Zusammenfassung:The invention relates to electrotechnical industry, more particularly to lithium-ion batteries, and even more particularly to lithium-ion batteries with silicon-containing negative electrode (anode). The invention provides a method for producing an anode slurry (paste), an anode slurry (paste), a method for producing an anode for a lithium-ion battery, an anode for a lithium-ion battery, and a lithium-ion battery with a high initial specific capacity and a long cycle life with a large number of charge-discharge cycles over which the battery retains at least 80% of its initial capacity. This technical result becomes possible due to the presence in the anode material of bundles of single-walled and/or double-walled carbon nanotubes having a length of less than 5 µm, together with bundles of single-walled and/or double-walled carbon nanotubes having a diameter of more than 500 nm and a length of more than 10 µm.
