Abstract
Provided is an electrode material which is suitable for use as a material for forming electrodes for use in lithium ion secondary batteries, etc. and which makes it possible to heighten the rate characteristics of batteries. The electrode material is characterized by comprising a polymer having, in a side chain, a fluoflavin skeleton such as that shown by the formula and an inorganic active material, the polymer being contained in an amount of 1 mass % or less with respect to the solid components.
Claims14
An electrode material comprising:
- a polymer having a fluoflavine skeleton in a side chain;
- and
- an inorganic active material,
- wherein the polymer is contained in an amount of 1 wt % or less in a solid content.
A polymer comprising a repeating unit having the following formula (1):
- wherein Z represents a partial structure having the following formula (Z-1), (Z-2), or (Z-3)
- wherein:
- RM represents a hydrogen atom or a methyl group,
- Y represents a single bond, —O—, —CO—, —COO—, —OCO—, —CH2-, —NH—, —NCH3-, —NHCO—, —CONH—, —CH2NHCO—, —CONHCH2-, or —S—, provided that when Z is the partial structure having formula (Z-1), Y is not —CH2NHCO—, and when Z is the partial structure having formula (Z-2), Y is not a single bond;
- R1s each independently represent a hydrogen atom, a halogen atom, a hydroxyl group, a carboxy group, an alkyl group having 1 to 10 carbon atoms which may be substituted with a halogen atom, an alkoxy group having 1 to 10 carbon atoms which may be substituted with a halogen atom, or an aryl group having 6 to 12 carbon atoms which may be substituted with a halogen atom;
- and
- * represents a bonding site.
