Yttrium-mediated bulk-surface stabilization of Ni-rich layered cathodes for high-voltage lithium-ion batteries
Zhipeng Wang, Jie Ding, Xiang Li, Ziqian Wang, Mingjiao Wu, Bo Shen, Yongshun Liang, Wei Bai, Fangkun Li, Mingwu XiangMicrowave-assisted synthesis of Y-modified NCM622 enables dual bulk/surface regulation, suppressing cation mixing, lattice degradation, CEI failure and interfacial impedance, thus boosting Li + kinetics and high-voltage cycling stability.
