ABSTRACT Lithium all‐solid‐state batteries (LASSBs) with sulfide‐type solid electrolytes (SEs) offer enhanced safety and higher energy densities compared to conventional Li‐ion batteries. However, Li‐metal anodes are incompatible with sulfide‐type SEs and prone to dendrite formation, which severely limits their practical applicability. Although various strategies, including the use of Li‐free, carbon‐based, alloy‐based, or oxide‐based anodes, as well as interfacial protection layers, have been explored, they typically deliver poor rate performance and suffer from dendrite growth. Herein, we introduce a Li–Ga compound anode, specifically the LiGa phase, predicted through density functional theory simulations, which exhibits dendrite‐free behavior, high ionic/electronic conductivities, stable operation at low stack pressures, room temperature stability, and excellent interfacial compatibility with SEs. Benefiting from these properties, a full cell comprising a LiGa anode and the LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM622) cathode (LiGa|NCM622) delivers a high areal capacity of 14.47 mAh cm −2 at a high cathode loading of 100 mg cm −2 , along with fast rate capability and stable cycling at a low stack pressure of 3 MPa at room temperature. Furthermore, a LiGa|NCM622 pouch cell demonstrates outstanding electrochemical performance, highlighting the potential of LiGa as a high‐performance anode for next‐generation LASSBs, with the concept broadly applicable to diverse Li‐based compounds.

Silicon is a promising anode material for all-solid-state Li-ion batteries (ASSLIBs), due to its high capacity; however, it suffers from considerable volume expansion (>300%) during cycling, resulting in poor capacity retention, low areal capacities, and low rate capabilities. To address these issues, we propose a μSi/SWCNT/LPSCl composite that effectively coats micrometer-sized Si (μSi) particles with Li6PS5Cl and single-walled carbon nanotubes (SWCNTs). This composite improved electrical and ionic conductivities, suppressed interface decomposition between μSi and the Li6PS5Cl solid electrolyte during cycling, and mitigated volume expansion to prevent cracks and contact loss. The μSi/SWCNT/LPSCl anode shows a high initial capacity (2974 mAh g–1 at a 0.1 C rate) and stable retention for 400 cycles. Furthermore, a full cell with this anode and a LiNi0.8Co0.1Mn0.1O2 cathode exhibited excellent reversibility and stable cycling performance. We anticipate this study will provide a solution for high-performance Si-based anodes in ASSLIBs.

A jitter-filtering retimer is presented with a wide-bandwidth injection-locked oscillator (ILO) based input clock-and-data recovery (CDR) unit cascaded with a jitter filter phase-locked loop (PLL) that generates low-jitter clocks for the output transmitter that serializes and retimes the recovered data. The input ILO-based CDR employs a quarter-rate architecture for efficient wide-range operation and utilizes a digital loop filter with pattern filtering for robust input delay line and ILO frequency control. Fabricated in 28 nm CMOS, the proposed retimer operates from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$12-20\text{Gb}/\mathrm{s}$</tex>, achieves the widest-reported <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$20\text{Gb}/\mathrm{s}$</tex> jitter tolerance (JTOL) of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1{\text{UI}}_{\text{PP}}$</tex> at a 173 MHz sinusoidal jitter (SJ) frequency and an estimated JTOL bandwidth in excess of 500 MHz, and consumes 58.66 mW.

Li metal anodes hold great promise for next-generation all-solid-state batteries (ASSBs) due to their high energy density. However, their practical implementation is severely limited by dendrite formation and interfacial instability, leading to rapid capacity degradation and short-circuiting. In this study, we introduce a Li2ZnSb (LZS) interlayer designed to suppress dendrite growth, enhance Li-ion transport, and improve Li reversibility. Electrochemical evaluations reveal that the LZS interlayer effectively stabilizes the Li metal–solid electrolyte interface, enabling highly reversible Li plating/stripping with superior cycling retention. To demonstrate the scalability of LZS, we developed a transfer printing method, successfully fabricating sheet-type LZS-Li anodes for integration into pouch-type ASSBs. The resulting pouch cells exhibit high areal capacity, excellent rate capability, and long-term cycling stability under low external pressure. These findings highlight LZS as a transformative interface engineering strategy, bridging the gap toward the practical realization of high-energy-density and long-lasting ASSBs.

Amorphous matrix-integrated Si nanocomposites were developed as high-performance anodes for Li-ion batteries (LIBs) and all-solid-state Li-ion batteries (ASSLIBs). Amorphous Ni₃ZnSi₂ was employed as the elastic and conductive matrix because its unique crystal structure readily undergoes amorphization during high-energy milling, yielding a Si/a-Ni₃ZnSi₂ nanocomposite in which Si nanocrystallites are uniformly encapsulated within the amorphous Ni₃ZnSi₂ matrix. The amorphous Ni₃ZnSi₂ matrix provides elastic recovery, high ionic/electronic conductivity, and effective buffering against large volume changes, thereby preserving electrode integrity during cycling. Incorporating a conductive graphite framework further produced dual-matrix Si/a-Ni₃ZnSi₂/G nanocomposites, where the amorphous Ni₃ZnSi₂ and graphite frameworks synergistically enhance charge transport and mitigate mechanical stress. The Si/a-Ni₃ZnSi₂/G anode exhibited high initial Coulombic efficiency, high-rate capability, and long-term cycling stability in both LIBs and ASSLIBs. In LIB full cells comprising a Si/a-Ni₃ZnSi₂/G anode and a LiNi_0.8Co_0.1Mn_0.1O₂ (NCM811) cathode, an energy density of 377.7 Wh kg^-1 was achieved with stable cycling performance and high-rate capability. In ASSLIB configurations with Li₆PS₅Cl solid electrolytes, the full cell delivered energy densities exceeding 300 Wh kg^-1 while maintaining electrochemical stability across wide ranges of temperature and current density. These findings highlight the scalability and potential applicability of Si/a-Ni₃ZnSi₂/G nanocomposites as next-generation anode materials for both LIBs and ASSLIBs.
