“…These values are hundreds of times higher than those obtained on the control Si or Si@Li 2 O electrode. Also, the negative extreme diffusion coefficient during the discharge process for the Si@Li 2 O and the Si@Li 2 O–lithicone electrodes might be caused by the laborious diffusion of Li + in Li 1.25±0.25 Si, Li 3.5±0.2 5Si, and Li 3.5±0.25 Si phases. ,, …”

“…17 Numerous attempts have been made to stabilize SEI, including the use of diverse Si nanostructures in combination with carbon composites and robust coatings. 18,19 Multifunctional binder/electrolyte additives, such as dopamine-grafted poly(acrylic acid) (PAA-DA), 20 polyrotaxanes additives, 13 or ether-based additives 21 that tailor the mechanical strength and components of SEI, have also been studied. Although these reports demonstrate longer cycle life, majority of their ICE are limited to 60−85%.…”

“…Also, the negative extreme diffusion coefficient during the discharge process for the Si@Li 2 O and the Si@Li 2 O−lithicone electrodes might be caused by the laborious diffusion of Li + in Li 1.25±0.25 Si, Li 3.5±0.2 5Si, and Li 3.5±0.25 Si phases. 18,69,70 A fundamental understanding of kinetic differences among the electrodes is also studied using DFT calculations. As LiF, Li 2 CO 3 , and Li 2 O are three major inorganic species in naturally formed SEIs, we next focus on the Li + diffusion in these species and the Li 2 O−lithicone film.…”

Silicon-based materials are of long-standing interest as the anodes for next-generation lithium-ion batteries, yet their low initial Coulombic efficiency and poor interfacial stability are lethal limitations. In this work, we used atomic layer deposition (ALD) and molecular layer deposition (MLD) techniques to fabricate a lithium-containing laminated Li 2 O−lithicone hybrid film (∼5 nm) on a silicon electrode. The laminated film provides an additional surface Li source around silicon cores, which can partially reimburse the Li loss during battery cycling. Characterization of interfacial components shows that such a laminated Li 2 O−lithicone interface undergoes gentle element changes and participates in a hybrid solid electrolyte interphase with Li 2 CO 3 , Li 2 O, Li x POF y , and LiF species. Finite element model analysis and morphology characterization demonstrate that the laminated structure design can help relieve the interfacial stress and thus retain the integrity and reactivity of the silicon composite anode during cycling. Moreover, the lithium-based laminated film leads to a fast Li + migration kinetics on the surface of the electrode as revealed by the galvanostatic intermittent titration technique and density functional theory calculation. Benefiting from the above merits, a silicon anode with a 91.2% initial Coulombic efficiency, a rate performance of 1460 mA h g −1 at 2 A g −1 , and a reversible capacity over 646 mA h g −1 after 850 cycles was achieved. This work exemplifies the advantages of lithium-based hybrid films precisely engineered by ALD/MLD techniques for improving performances of advanced silicon anode batteries and deepens understandings on the mechanism of interfacial stability and reaction kinetics.

In this review, we emphasize the significant potential of carbon group element-based (Group-IV) electrochemical energy devices prepared on the basis of ion migration in the realm of high-efficiency batteries. Based primarily on our group research findings, we elucidate the key advantages of traditional Group-IV materials as electrodes in ion batteries powered by metal ion migration. Subsequently, we delve into the operational principles and research progress of iterative Group-IV material moisture ion batteries, driven by ion migration through external moisture. Finally, considering the practical challenges and issues in real-world applications, we offer prospects for the development and commercialization of Group-IV materials utilizing ion migration in both conventional and next-generation battery technologies.

To stabilize the Earth’s climate, large-scale transition is needed to non-carbon-emitting renewable energy technologies like wind and solar energy. Although these renewable energy sources are now lower-cost than fossil fuels, their inherent intermittency makes them unable to supply a constant load without storage. To address these challenges, rechargeable electric batteries are currently the most promising option; however, their high capital costs limit current deployment velocities. To both reduce the cost as well as improve performance, 3D printing technology has emerged as a promising solution. This literature review provides state-of-the-art enhancements of battery properties with 3D printing, including efficiency, mechanical stability, energy and power density, customizability and sizing, production process efficiency, material conservation, and environmental sustainability as well as the progress in solid-state batteries. The principles, advantages, limitations, and recent advancements associated with the most common types of 3D printing are reviewed focusing on their contributions to the battery field. 3D printing battery components as well as full batteries offer design flexibility, geometric freedom, and material flexibility, reduce pack weight, minimize material waste, increase the range of applications, and have the potential to reduce costs. As 3D printing technologies become more accessible, the prospect of cost-effective production for customized batteries is extremely promising.
