    Abstract: A positive electrode material, a positive electrode, and a battery employing the same are provided. The positive electrode material includes an active particle and a modified layer covering the surface of the active particle. The modified layer is a reaction product of a composition. The composition includes an ionic conductive ceramic compound, an organic conductive compound, and a coupling agent. In the disclosure, the ionic conductive ceramic compound is 50-84 parts by weight, the organic conductive compound is 16-50 parts by weight, and the total weight of the ionic conductive ceramic compound and the organic conductive compound is 100 parts by weight. In the disclosure, the weight percentage of the coupling agent is from 0.05 wt % to 10 wt %, based on the total weight of the ionic conductive ceramic compound and the organic conductive compound.
