Abstract
A battery capable of improving cycle characteristics is provided. An anode active material layer is formed by forming a precursor layer containing active material particles containing Si and Li as an element, and then heating the resultant. Thereby, the active material particles are bound to each other by sintering or fusing, and united three-dimensionally. Since Li is contained therein, the active material particles can be sufficiently sintered even if the heating temperature is low, 600 deg C.
Claims25
An anode having an anode current collector and an anode active material layer provided on the anode current collector,
- wherein the anode active material layer has a structure in which active material particles containing silicon (Si) and lithium (Li) as an element are bound to each other by sintering or fusing.
A battery comprising:
- a cathode;
- an anode;
- and an electrolyte,
- wherein the anode has an anode current collector and an anode active material layer provided on the anode current collector, and
- the anode active material layer has a structure in which active material particles containing silicon (Si) and lithium (Li) as an element are bound to each other by sintering or fusing.
A method of manufacturing an anode including a step of forming an anode active material layer by forming a precursor layer containing active material particles containing silicon (Si) and lithium (Li) as an element on an anode current collector, heating the resultant, and thereby binding the active material particles to each other by sintering or fusing.
