“…After the second cycle, the charge curve differed from the first and exhibited two potential plateaus at around 0.6 and 0.3 V vs K + / K, corresponding to KSb and K 3 Sb formation, respectively. 47,48 The discharge capacity increased with each cycle due to FeSb 2 activation, which was confirmed in an organic-solventbased electrolyte. 30 The CE values exceeded 99.0% in the sixth cycle and reached 99.9% in the 32nd cycle.…”

Maintaining the sustainability of society demands the strategic use of multipurpose rechargeable batteries. One promising option is K-ion batteries (KIBs), which are suitable as large stationary storage batteries and store renewable energy because of their abundant K resources. Herein, the anode properties of different binary antimonide (MSb x ; M: metal) electrodes were investigated for KIBs in an ionic-liquid electrolyte. The results indicated that although Sb and SnSb electrodes exhibited a high initial reversible capacity, their cycle stability was poor. In contrast, rare-earth antimonide (LaSb, SmSb, and YSb) electrodes showed extremely long cycle stability over 500 cycles with a capacity approximately one-third that of the Sb electrode. Interestingly, rare-earth antimonides possess seamless alloying and dealloying with K without undergoing phase separation into rare-earth and Sb phases. Additionally, other MSb x electrodes, such as FeSb2, FeSb, and AlSb, exhibited relatively higher reversible capacity and cycle stability when M was K-inactive. These electrodes possessed moderate Mohs hardness and low electrical resistance and caused MSb x phase separation into M and Sb phases. Notably, the stiff M phase effectively withstood the compressive stress produced by Sb and provided a supporting skeleton. Our study will provide insight into the physicochemical properties of M alloyed with Sb to achieve excellent cycle stability in KIBs and reveal that the same active material demonstrated different anode properties than Na-ion batteries.

Antimony (Sb) holds a high theoretic capacity and suitable redox potential as a promising anode for aqueous alkaline batteries (AABs). However, the uncontrollable nucleation for SbO2− and promiscuous water‐induced side reactions severely degrade the reversibility of Sb anode. Herein, the carbon‐anchored Sb nanoparticles are constructed to induce uniform Sb plating/stripping for high‐performance AABs. The experimental results reveal that the enhanced interaction between carbon and antimony as well as defective carbon can significantly improve the electrical conductivity and decrease the Sb nucleation overpotential. Accordingly, the as‐prepared Sb anode enables preferential plating of Sb rather than parasitic side reactions. As a result, the cycle life of A‐Sb/CF is sustained over 500 cycles at 10 mA cm−2/2 mAh cm−2. Even at the high capacity of 4 mAh cm−2, this anode can cycle stably for 225 cycles, which is significantly better than the Sb/CF counterpart. Furthermore, the assembled Ni3S2@Ni(OH)2//A‐Sb/CF full battery demonstrates a high capacity of 2.17 mAh cm−2 and a stable cycle life of over 500 cycles.
