Redox-active Co(II) and Zn(II) Pincer Complexes as High-Capacity Anode Materials for Lithium-Ion Batteries.

ABSTRACT: To address the ongoing demand for high-performance energy storage devices, it is crucial to identify new electrode materials. Lithium-ion batteries (LIBs) store energy via the electrochemical redox process, so their electrode materials should have reversible redox properties for rechargeability. On that note, redox-active metal complexes are explored as innovative electrode materials for LIBs. Redox-active metal(II) chloride complexes (MCC) demonstrate promising potential as anode materials, exhibiting high capacity and excellent rate capability. In particular, zinc(II) chloride complexes, referred to as ZCC, achieve a capacity of 1720 mAh g^-1 at 2.0 A g^-1 over 200 cycles. Additionally, the lithium-ion storage mechanism of MCC is elucidated using ex situ analyses of M
