Given their high energy/power densities and long cycle time, lithium‐ion batteries (LIBs) have become one type of the most practical power sources for electric/hybrid electric automobile, portable electronics, and power plants. However, the performance attenuation of LIBs has limited their applications in many energy‐related systems. In this review, the performance attenuation mechanisms of LIBs and the effort in development of mitigation strategies are comprehensively reviewed in terms of the commonly used cathode materials and anode materials, electrolytes, and current collectors. Several challenges are analyzed and several further research directions are also proposed for overcoming the challenges toward improvement of LIB performance.

[102] Vinyl Tris(2-methoxyethoxy) Silane (VTMS): VTMS was used as an additive in conventional organic carbonate-based electrolyte with Si/C composite electrodes by Wang et al They found the optimum amount to be 5 wt% and demonstrated that the formed SEI is much thinner than in the baseline electrolyte, interfacial resistance significantly reduced and achievable reversible capacity overall higher, although the rate of capacity fading does not seem to be influenced by the presence of VTMS. XPS analysis of the electrodes after cycling revealed the presence of siloxane and oxysilane species in the SEI that were not detected in the baseline electrolyte.…”

As the demand for mobile energy storage devices has steadily increased during the past decades due to the rising popularity of portable electronics as well as the continued implementation of electromobility, energy density has become a crucial metric in the development of modern batteries. It was realized early on that the successful utilization of silicon as negative electrode material in lithium‐ion batteries would be a quantum leap in improving achievable energy densities due to the roughly ten‐fold increase in specific capacity compared to the state‐of‐the‐art graphite material. However, being an alloying type material rather than an intercalation/insertion type, silicon poses numerous obstacles that need to be overcome for its successful implementation as a negative electrode material with the most prominent one being its extreme volume changes on (de‐)lithiation. While, as of today, a plethora of different types of Si‐based electrodes have been reported, a universally common feature is the interface between Si‐based electrode and electrolyte. This review focuses on the knowledge gained thus far on the impact of different liquid electrolyte components/formulations on the interfaces and interphases encountered at Si‐based electrodes.

Lithium‐ion batteries (LIBs) have been occupying the dominant position in energy storage devices. Over the past 30 years, silicon (Si)‐based materials are the most promising alternatives for graphite as LIB anodes due to their high theoretical capacities and low operating voltages. Nevertheless, their extensive volume changes in battery operation causes the structural collapse of Si‐based electrodes, as well as severe side reactions. In this review, the preparation methods and structure optimizations of Si‐based materials are highlighted, as well as their applications in half and full cells. Meanwhile, the developments of promising electrolytes, binders and separators that match Si‐based electrodes in half and full cells have made great progress. Pre‐lithiation technology has been introduced to compensate for irreversible Li+ consumption during battery operation, thereby improving the energy densities and lifetime of Si‐based full cells. More importantly, almost all related mechanisms of Si‐based electrodes in half and full cells are summarized in detail. It is expected to provide a comprehensive insight on how to develop high‐performance Si‐based full cells. The work can help us understand what happens during the lithiation process, the primary causes of Si‐based half and full cells failure, and strategies to overcome these challenges.
