“…Lou, Ci, and coworkers utilized Si NPs as a template for COF synthesis with the intention of providing a robust, artificial solid-electrolyte interphase (SEI) layer. 73 Combining Tp with 2,5-diaminobenzenesulfonic acid and prefabricated Si NPs under solvothermal conditions yielded Si@COF NPs (Figure 19a). When assembled into a LIB, Si@COF demonstrated stability and efficiency that was markedly improved over uncoated Si NPs.…”

Covalent organic frameworks (COFs) are an advanced class of crystalline porous polymers that have garnered significant interest due to their tunable properties and robust molecular architectures. As a result, COFs with energy-storage properties are of particular interest to the field of rechargeable battery electrode materials. However, investigation into COFs as candidates for energy-storage materials is still in its infancy. This review will highlight methods used to fabricate COFs used as electrode materials and discuss the factors that prove critical for their production. A collection of known COF-based energy-storage systems will be featured. In addition, the ability to utilize the storage properties of COFs for systems beyond traditional Li-ion batteries will be addressed. An outlook will address the current progress and remaining challenges facing the field to ultimately expand the scope of their applications.

“…Silicon monoxide (SiO) represents an attractive anode material for high-energy density LIBs for its high theoretical capacity (2680 mAh g −1 , assuming all the Si in SiO can be converted into Li 4.4 Si during lithiation) [3,4]. However, SiO anodes are generally plagued with inherently poor charge (electrons and ions) transport properties and the large volume change that leads to rapid pulverization during cycling, both of which limit the achievable mass loading and contribute to poor cycling performance with rapidly fading capacity [5][6][7].…”

Silicon monoxide (SiO) is an attractive anode material for next-generation lithium-ion batteries for its ultra-high theoretical capacity of 2680 mAh g−1. The studies to date have been limited to electrodes with a relatively low mass loading (< 3.5 mg cm−2), which has seriously restricted the areal capacity and its potential in practical devices. Maximizing areal capacity with such high-capacity materials is critical for capitalizing their potential in practical technologies. Herein, we report a monolithic three-dimensional (3D) large-sheet holey graphene framework/SiO (LHGF/SiO) composite for high-mass-loading electrode. By specifically using large-sheet holey graphene building blocks, we construct LHGF with super-elasticity and exceptional mechanical robustness, which is essential for accommodating the large volume change of SiO and ensuring the structure integrity even at ultrahigh mass loading. Additionally, the 3D porous graphene network structure in LHGF ensures excellent electron and ion transport. By systematically tailoring microstructure design, we show the LHGF/SiO anode with a mass loading of 44 mg cm−2 delivers a high areal capacity of 35.4 mAh cm−2 at a current of 8.8 mA cm−2 and retains a capacity of 10.6 mAh cm−2 at 17.6 mA cm−2, greatly exceeding those of the state-of-the-art commercial or research devices. Furthermore, we show an LHGF/SiO anode with an ultra-high mass loading of 94 mg cm−2 delivers an unprecedented areal capacity up to 140.8 mAh cm−2. The achievement of such high areal capacities marks a critical step toward realizing the full potential of high-capacity alloy-type electrode materials in practical lithium-ion batteries.
