“…Figure 4a depicts CV curves of the optimized SnS@C/rGO at a scan rate of 0.2 mV s −1 in a potential range of 0.01-3.0 V versus Li/Li + . In the initial scan, an obvious reduction peak at about 1.2 V appears, which is related to conversion reaction of SnS with Li + (SnS + xLi + + xe − → Li x S + Sn) [7,33] and formation of solid electrolyte interphase (SEI). Subsequent peaks in the range of 0.1-0.7 V are attributed to multi-step alloying process of Sn with Li + (Sn + xLi + + xe − → Li x Sn).…”

“…The introduction of carbon can effectively enhance the electrical conductivity and buffer the volume variations. [18,[29][30][31][32][33][34] Because SnS is conventionally prepared from reduction of SnS 2 precursor at high temperature, growth and agglomeration of SnS particles are inevitable in the preparation process. Under such circumstance, confining SnS by carbon materials is crucial in the preparation to achieve high performance of reversible Li + storage.…”

SnS with high theoretical capacity is a promising anode material for lithium‐ion batteries. However, dramatic volume changes of SnS during repeated discharge/charge cycles result in fractures or even pulverization of electrode, leading to rapid capacity degradation. To solve this problem, we construct a dual‐carbon‐confined SnS nanostructure (denoted as SnS@C/rGO) by depositing semi‐graphitized carbon layers on reduced graphene oxide (rGO) supported SnS nanoplates during high‐temperature reduction. The dual carbon of rGO and in situ formed carbon coating confines growth of SnS during the high‐temperature calcination. Moreover, during the reversible Li+ storage the dual‐carbon modification enables good electronic conductivity, relieves the volume effect, and provides double insurance for the electrical contact of SnS even after repeated cycles. Benefiting from the dual‐carbon confinement, SnS@C/rGO exhibits significantly enhanced rate capability and cycling stability compared with the bare and single carbon modified SnS. SnS@C/rGO presents reversible capacity of 1029.8 mAh g−1 at 0.2 A g−1. Even at a high current density of 1 A g−1, it initially delivers reversible capacity of 934.0 mAh g−1 and retains 98.2% of the capacity (918.0 mAh g−1) after 330 cycles. This work demonstrates potential application of dual‐carbon modification in the development of electrode materials for high‐performance lithium‐ion batteries.

BACKGROUND: Due to the high energy density of lithium-ion batteries, they have become the main power sources for electric vehicles. However, lithium-ion batteries suffer from severe capacity fading during their electrochemical cycles. Therefore, it is significant to develop perfect electrode materials for lithium-ion batteries. It is known that the traditional anode materials have low specific capacity value and poor cycle performance. To overcome this problem, a novel anode material is designed in our work. RESULTS: In electrochemical tests, the initial specific capacity of the NiCo 2 O 4 spheres/nanosheets (NCOs/n) electrode is as high as 1426 mAh g −1 at the current density of 0.2 C. The capacity of the NCOs/n electrode can maintain at 1020 mAh g −1 at the current density of 1C after 1000 cycles. CONCLUSIONS: The as-prepared NCOs/n electrodes exhibit high specific capacity value and superior cycle stability in high current densities.
