In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

电压谐波对MOA泄漏电流检测方法影响分析

open access: yesDianci bileiqi, 2012
电网电压谐波不仅对MOA泄漏电流中的容性分量带来干扰,而且对阻性分量也带来干扰。分析了电压谐波对两种基本方法-补偿法与谐波分析法的影响,并对补偿法进行了仿真计算,补偿法必须考虑容性谐波的干扰,谐波分析法避开了容性谐波的干扰,两种方法都不能消除阻性电流中直接来自电压谐波中的分量,综述目前已有消除电压谐波影响的方法,可根据阻性电流基波分量计算出阻性电流值及谐波分量,阻性电流中来自系统电压谐波干扰部分的消除还需进一步分析。

Micro‐Macro Regulation Through Co‐Intercalation of Inorganic–Organic for the V2O5·nH2O Cathode Toward High‐Performance Aqueous Zinc‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

基于阻容网络的避雷器阻性电流计算方法研究

open access: yesGaoya dianqi, 2019
避雷器是目前防止雷击过电压最为有效的措施,其中应用最为广泛的避雷器类型就是氧化锌避雷器。阻性电流是对氧化锌避雷器的健康状态进行判断的重要依据,但是由于部分电容干扰,现有测量方式很难从全电流中准确得到阻性电流。文中以500 kV氧化锌避雷器为例,利用MATLAB中的Simulink模块对三相避雷器进行简化建模,考虑了避雷器的分节情况,考虑了各节之间的部分电容和各相之间的相间电容,得到了三相分节的避雷器阻容网络路模型,可以有效地滤除全电流中的容性分量,计算得到阻性电流。对于路模型中的各部分电容的取值 ...

Participation Disenchants: How Online Political Participation Decreases Online Political Efficacy in China

open access: yesRegulation &Governance, Volume 20, Issue 1, Page 35-63, January 2026.
ABSTRACT Existing literature largely agrees that authoritarian regimes establish channels for political participation to gather valuable information on citizens' anti‐regime sentiments and policy preferences and to supervise lower‐level bureaucrats and firms.

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English

open access: yesInternational Journal of Applied Linguistics, Volume 35, Issue 4, Page 1938-1952, November 2025.
ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

高压直流换流站内ZnO阀片的小电流伏安特性的研究

open access: yesDianci bileiqi, 1987
为研究高压直流换流站内无间隙避雷器阀片的小电流伏安特性,测试了三类国产ZnO阀片在换流站内不同电压作用下的小电流伏安特性,分析了阀片在各种复杂电压下伏安特性的规律和电压波形对阀片非线性程度的影响;指出:在非正弦电压作用下,测量阀片阻性电流的回路应该考虑阀片的电容是随频率变化而变化的这一事实,必须补偿掉各种频率下阀片中的容性电流成分才能比较精确地测得流过阀片中的阻性电流。
