Nonetheless, the use of Si-based electrodes usually leads to a gradual loss in the cell's electrochemical performance due to the significant volume expansion of silicon in electrode reactions. Combining silicon, a poor electronic conductor, with an electronically conductive Li-inactive phase, is a promising strategy to alleviate the volume expansion of silicon during lithiation and delithiation while providing a robust electronic network. Si-Fe alloys are prospective candidates which could be used to maintain the electronic network in the silicon electrodes. In this study, different Si-Fe alloys are synthesized using ball-milling (BM) and arc melting (AM) techniques, leading to highly different chemical compositions and powder morphologies to better understand the role of iron silicide inactive phases in electrochemical reactions and optimize their performance. The use of AM results in the formation of Si and α-Fe₂Si₅ conducting matrix in a desired ratio, as expected from the Si-Fe binary phase diagram, while BM generates a mixture of phases, including undesirable products. Thanks to the presence of the inactive iron silicide phase (α-Fe₂Si₅), the electrical conductivity of the Si/α-Fe₂Si₅ composite can be increased up to 10³ S m^-1, five orders of magnitude compared to pristine Si. The electrochemical testing results show that the performance of such a composite is strongly influenced by the balance between Si and inactive iron silicide phase, as well as their interparticle contact. Dilatometry tests in full cell configuration also demonstrate the advantage of using α-Fe₂Si₅ as a matrix to buffer Si volume change, prevent the loss of active material, and maintain a reversible swelling of 24 % throughout cycling up to the 45th cycle. After optimization of electrode and electrolyte formulations, such composites could significantly outperform current Si/C electrodes in terms of volumetric capacity, rate capability and long-term cycling.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"75 ","pages":"Article 104086"},"PeriodicalIF":18.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The battery delivers high specific capacity and acceptable reversibility in the early cycles at 50 °C, and capacity decay occurs with the increased cycles; at 0 °C, the battery shows high polarization, low specific capacity, and poor cycle stability. As revealed by electrochemical analysis, the battery performance at 0 °C is mainly limited by the sluggish interfacial kinetics and the uneven SEI layer with a low proportion of LiF and a high content of Li_xO_y. In contrast, high temperature accelerates the side reaction between electrolyte and cathode, inducing electrolyte decomposition, gas generation, and mechanical pulverization. Moreover, theoretical simulation reveals that the average cell temperature at 273 K is the highest. Both NCM523 cathode and graphite anode at 273 K have the greatest stress and deformation after one cycle at 8C, and the most cracks found on the cycled NCM523 particles at 323 K are mainly due to its severe side reaction.
