具有高稳定性的电极活性材料及使用该材料的电化学装置
摘要：
本文公开了一种通过表面酸性位点的调节而使稳定性得到改善的电极活性材料；一种包含所述电极活性材料的电极，该电极表面涂覆有具有酸性位点的化合物或者混合有具有酸性位点的化合物；和一种电化学装置，该装置包含所述电极从而使其效能提高。通过调节所述电极活性材料表面的酸性位点来减少与电解质的副反应、保持电极活性材料的结构稳定性，从而提高电池效能。
摘要（英）：

Disclosed are an electrode active material, of which the stability is improved by adjusting an acid site of a surface of the electrode active material, an electrode containing the electrode active material, having a surface coated with a compound having an acid site, or mixed with the compound having the acid site and an electrode material, and an electrochemical device having the electrode to enhance its performance. By adjusting the acid site on the surface of the electrode active material, the side reaction with the electrolyte is decreased, and the structure stability of the electrode active material is secured, thereby enhancing the performance of the battery.
