“…Accordingly, the reaction mechanism of SiO to storage Li + ions is generally premised to include reversible and irreversible parts. [ 55,56 ] The irreversible reaction is usually written as follows: [ 55,56 ]

\begin{matrix} SiO + 2 {Li}^{+} + 2 {normale}^{- 1} \to {Li}_{2} O + Si \end{matrix}

\begin{matrix} Si O + 4 {Li}^{+} + 4 {normale}^{- 1} \to {Li}_{4} {SiO}_{4} + 3 Si \end{matrix}

To dispose the fragility and poor conductivity problems of SiO‐based anode materials, a “phase change mediation combined with cord reinforcing” concept is proposed, in which graphene cord is in situ fabricated combined with Si and SiO2 nanodomains generated in the SiO matrix via chemical vapor deposition. Being the fabricated composite, graphene cord not only bridges but also wraps the SiO particles, improving the electrical conductivity and flexibility of the fabricated SiO@Gra anode. Moreover, the increased SiO2 regions in the Si/SiO matrix alleviate volume change and release the strain for Li+ insertion, enhancing the tenacity of the SiO electrode according to the phase transformation flexibility mechanism. Besides, the grain boundaries and interfaces among the Si/SiO2/SiO regions contribute to additional Li+ storage and pledge more channels for Li+ transfer and electrolyte wetting. The merit of Si/SiO2/SiO synergistically contributes to the ascendant electrochemical performance of the SiO anodes. The as‐fabricated SiO@Gra anodes deliver a high reversible capacity of 1127 mAh g−1 at 0.2 A g−1 with 87% capacity retention after 200 cycles. The proposed phase change and cord reinforcing not only deepen the understanding of the electrochemical reaction mechanism of Li+ in SiO, but also inspire a rational design tactic for advanced lithium‐ions batteries.

“…Recently, Li's group proposed asymmetric membranes containing SiO micron-sized powders and carboxymethyl glue, which demonstrated 99.82% CE and >95% capacity retention after 110 cycles at a current density of 400 mA g −1 . 27 Nonetheless, these lab-scale techniques usually require tedious processing steps and are thus not easy to be scaled up. Moreover, the half-cell evaluations are mostly targeted to optimize several key performance metrics, that is, gravimetric capacity, rate behavior, or cycle life, at the penalty of fully discharged compaction density or areal mass loading, which are also indispensable in the full-battery assessment and cannot be omitted.…”

Si anodes suffer from poor cycling efficiency because of the pulverization induced by volume expansion, lithium trapping in Li–Si alloys, and unfavorable interfacial side reactions with the electrolyte; the comprehensive consideration of the Si anode design is required for their practical deployment. In this article, we develop a cabbage-inspired graphite scaffold to accommodate the volume expansion of silicon particles in interplanar spacing. With further interfacial modification and prelithiation processing, the Si@G/C anode with an areal capacity of 4.4 mA h cm–2 delivers highly reversible cycling at 0.5 C (Coulombic efficiency of 99.9%) and a mitigated volume expansion of 23%. Furthermore, we scale up the synthetic strategy by producing 10 kg of the Si@G/C composite in the pilot line and pair this anode with a LiNi0.8Co0.1Mn0.1O2 cathode in a 1 A h pouch-type cell. The full-cell prototype realizes a robust cyclability over 500 cycles (88% capacity retention) and an energy density of 301.3 W h kg–1 at 0.5 C. Considering the scalable fabrication protocol, holistic electrode formulation design, and harmony integration of key metrics evaluated both in half-cell and full-cell tests, the reversible cycling of the prelithiated silicon species in the graphite scaffold of the composite could enable feasible use of the composite anode in high-energy density lithium batteries.

“…Therefore, tremendous effort has been made to explore the fundamental basics of high-capacity and high-energy electrode materials and many strategies have been proposed to conquer the obstacles of boosting energy density of the batteries. − One strategy is to reduce particle size to nanoscale to alleviate mechanical strain. For example, Liu et al found that, during the first lithiation process, the nanoparticles with diameters less than 150 nm undergo volume expansion without fracturing or cracking, suggesting that nanoparticles can tolerate huge volume change .…”

The United States is by far the largest corn producer worldwide, with corn yields steadily increasing for the past decades. In many midwestern U.S. states such as Iowa, Illinois, and Nebraska, corn farmers currently grow more corn than consumers can utilize as human food or animal feed. To sustain the economic viability of corn farmers, it is critical that new uses and markets for corn, corn byproducts from harvesting, corn industrial products, and corn byproducts from industrial processing should be discovered, giving the highest return to corn producers. With the increasing popularity of electric vehicles and grid-level energy storage systems for renewable energy, there has been an evergrowing interest in improving existing energy storage technologies as well as developing new ones. During this development, a great amount of effort has been focused on exploiting cost-effective solutions utilizing sustainable materials derived from renewable biomass. In this Perspective, innovative and economically beneficial uses of corn and corn products in various energy storage applications, such as lithium-ion batteries, solid-state batteries, and redox flow batteries, are looked at comprehensively, which may shed light on how to establish an environmentally sustainable, technically feasible, and economically beneficial solution to support the corn industry.
