The obtained results demonstrated the successful preparation of LSbC-10 with exceptional properties. The LSbC-10 exhibits enhanced crystallinity and an increased Ti<sup>3+</sup>/Ti<sup>4+</sup> ratio, which promotes the material’s conductivity, while the polarization resistance decreased significantly. Building upon the LTO, the rate capability (5C/1C) has been boosted to 83.41%, while the reversible capacity retention rate (0.1C(re)/0.1C) has increased to 93.27%. The Li<sup>+</sup> diffusion coefficient also doubled to achieve a value of 1.5316 × 10<sup>−9</sup> cm<sup>2</sup> s<sup>−1</sup>. After undergoing fast charge–discharge at a rate of 5C for 1000 cycles, the capacity reached 228.53 mAh g<sup>−1</sup>, representing a remarkable increase of 43.05% compared to the LTO (159.75 mAh g<sup>−1</sup>). Compared with the recently reported Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> composites, the rate capability still had obvious advantages. In the meantime, straightforward and green processes can reduce the pressure on the environment during industrial production. The outstanding performance exhibited by LSbC-10 not only demonstrates that Sb<sup>3+</sup>-doped and CNT-wrapping significantly enhances the market competitiveness of Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> but also provides a new model for the study of insertion anode electrode composite conversion/alloying anode electrode besides single doping or coating.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 2","pages":"707 - 718"},"PeriodicalIF":2.1,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plasticity and fatigue behaviors of AlSi10Mg alloy parts manufactured by selective laser melting (SLM) are generally poor. Thus, this paper studies the microstructure and mechanical properties of SLM-manufactured AlSi10Mg alloy under aging, annealing, solution and T6 heat treatments. The results demonstrate that these heat treatments enhance the plasticity of the material, especially for the T6 treatment, which exhibits a plasticity 3.2 times greater than that of the as-deposited alloy. However, the tensile and yield strengths of the AlSi10Mg alloy decrease. The T6 treatment exhibits the highest fatigue life, which is five times higher than that of the as-deposited alloy. The microstructure of the annealing treatment consists of reticulated eutectic Si, while the aging treatment displays reticulated Si fractures and an increased presence of spherical Si particles. In contrast, the solution and T6 treatments exhibit blocky Si structures and micropores. The microstructural alteration of the silicon state after heat treatment is attributed to the enhanced fatigue life.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1148 - 1160"},"PeriodicalIF":2.1,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
