Biomimetics‐Inspired Architecture Enables the Strength–Toughness of Ultrahigh‐Loading Silicon Electrode

Advanced Functional Materials, Год журнала: 2024, Номер 34(22)

Опубликована: Фев. 6, 2024

Abstract Silicon (Si), as one of the most promising anode candidates, is expected to improve energy density Li−ion batteries due its high specific capacity (≈4200 mAh g −1 ). However, cyclic performance Si unsatisfactory for practical usage inadequate toughness when exceeding mass loading beyond 2 mg cm −2 , which triggers unceasing electrode breakage. Here, a biomimetic created by interconnecting vertically aligned graphene oxide sheets with conductive carbon nanotubes (AGO−Si/C). Unlike reported structures, AGO−Si/C exhibits superior interlaminar owing unique crumpling architecture reversible interlayer slipping. The elastic structure releases accumulative lithiation stress nanoparticles address degraded inactivation. Thus, shows long−lived cycles toughening structure, allowing fabrication very thick (4.1 ) an impressive areal 10.0 . This discovery offers easily scalable method graphite/Si that exceeds commercial−level 5

Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Фев. 23, 2024

Abstract Adopting a nano- and micro-structuring approach to fully unleashing the genuine potential of electrode active material benefits in-depth understandings research progress toward higher energy density electrochemical storage devices at all technology readiness levels. Due various challenging issues, especially limited stability, micro-structured (NMS) electrodes undergo fast performance degradation. The emerging NMS scaffold design is pivotal aspect many as it endows them with both robustness enhancement, even though only occupies complementary facilitating components for main mechanism. However, extensive efforts are urgently needed optimizing stereoscopic geometrical scaffolds minimize volume ratio maximize their functionality fulfill ever-increasing dependency desire power source supplies. This review will aim highlighting these strategies, summarizing corresponding strengths challenges, thereby outlining solutions resolve principles, key perspectives future in this field. Therefore, be one earliest reviews from viewpoint.

Direct Ink Writing 3D Printing for High‐Performance Electrochemical Energy Storage Devices: A Minireview

Advanced Science, Год журнала: 2023, Номер 10(32)

Опубликована: Сен. 22, 2023

Abstract Despite tremendous efforts that have been dedicated to high‐performance electrochemical energy storage devices (EESDs), traditional electrode fabrication processes still face the daunting challenge of limited energy/power density or compromised mechanical compliance. 3D thick electrodes can maximize utilization z ‐axis space enhance EESDs but suffer from limitations in terms poor stability and sluggish electron/ion transport. Direct ink writing (DIW), an eminent branch printing technology, has gained popularity manufacture with intricately designed architectures rationally regulated porosity, promoting a triple boost areal mass loading, ion diffusion kinetics, flexibility. This focus review highlights fundamentals printable inks typical configurations 3D‐printed devices. In particular, preparation strategies for multifunctional are systemically discussed classified according performance evaluation metrics such as high density, power volumetric Challenges prospects outlined, aiming provide valuable insights into this thriving field.
