| 1 | Duality of Li_(2)CO_(3) in Solid-State Batteries显示文摘Solid-state batteries(SSBs)have been considered the most promising technology because of their superior energy density and safety.Among all the solid-state electrolytes(SEs),Li_(7) La_(3) Zr_(2) O_(12)(LLZO)with high ionic conductivity(3×10^(−4) S/cm)has been widely investigated.However,its large-scale production in ambient air faces a challenge.After air exposure,the generated Li_(2)CO_(3) layer deteriorates the ionic conductivity and interfacial wettability,thus greatly compromising the electrochemical performance of SSBs.Many works aim to eliminate this layer to recover the pristine LLZO surface.Unfor-tunately,few articles have emphasized the merits of Li_(2)CO_(3).In this review,we focus on the two-sidedness of Li_(2)CO_(3).We discuss the various characteristics of Li_(2)CO_(3) that can be used and recapitulate the strategies that utilize Li_(2)CO_(3).Insulating Li_(2)CO_(3) is no longer an obstacle but an opportunity for realizing intimate interfacial contact,high air stability,and outstand-ing electrochemical performance.This review aims to off er insightful guidelines for treating air-induced Li_(2)CO_(3) and lead to developing the enhanced air stability and electrochemical performance of LLZO. | Xuerui Yi Yong Guo Siyuan Pan Yiqiao Wang Sijia Chi Shichao Wu Quan-Hong Yang | 2023 | Transactions of Tianjin University2023，29，1： | 0 |
| 2 | A Ka-band calibratable phased-array front-end chip with high element-consistency显示文摘Dear editor,Active phased arrays are widely used in radar and communication systems due to their characteristics such as rapid wave beam steering, agile beamforming, and spatial power synthesis. The phased-array system contains a large number of elements. Three critical components in each element are precise amplitude control, precise phase control, and signal amplification. | Shiyan SUN An'an LI Yingtao DING Zipeng CHEN Wei WANG Sijia JIANG Zhiming CHEN Baoyong CHI | 2022 | Science China(Information Sciences)2022，65，12： | 0 |
