摘要
封底图片：高压钴酸锂可提供高容量，从而显著提高锂离子电池的能量密度。然而，其循环性差仍然是商业应用中的一个问题。在编号为 CEY2-2024-0118 的文章中，Ding 等人提出了一种简便而有效的方法来解决这一问题，即在空气环境下通过热解锂化聚偏氟乙烯预涂层在钴酸锂表面构建锂氟改性层。所制备的锂化物改性层可有效抑制界面副反应和表面结构退化，从而大大提高钴酸锂阴极在 4.6 V 高电荷截止电压下的循环稳定性。

Back cover image: High-voltage LiCoO2 can deliver a high capacity and therefore significantly boost the energy density of Li-ion batteries. However, its poor cyclability is still an issue for commercial applications. In article number CEY2-2024-0118, Ding et al. proposed a facile but effective methode to address this issue by constructing a LiF modification layer on LiCoO2 surface via pyrolysis of the lithiated polyvinylidene fluoride pre-coating under air atmosphere. The as-fabricated LiF layer can effectively suppress the interfacial side reactions and surface structure degradation, and thereby greatly enhance the cycling stability of LiCoO2 cathode at high charge cutoff voltage of 4.6 V.
