탄소나노튜브 필름 Li Host의 Lithiophilicity가 리튬메탈 배터리의 성능에 미치는 영향 연구 = Effect of the Lithiophilicity of the Li Host of a Carbon Nanotube Film on the Performance of Li Metal Battery

다국어 초록 (Multilingual Abstract)

Lithium (Li) has gained attention as an anode material because of its high specificcapacity (3860 mAh g-1) and high energy density. However, its commercialization islimited owing to the dendrite growth on the surface of the electrode, which causes severaldrawbacks, such as low cycling stability, and safety issues, such as short circuits due to thepenetration of the separator. Li hosts with various structures have been studied to addressthese problems. A 3D-scaffold structured host effectively suppresses the Li dendritegrowth and improves the electrode performance. Carbon nanotube (CNT) is a promisingcandidate material for a Li host owing to its high surface area and excellent electrical conductivity.
However, the lithiophobicity of CNT makes it difficult to utilize CNT as a Li host. Inthis study, we tried to improve the lithiophilicity of CNT film by direct pre-lithiation methodand studied the effect of lithiophilicity on the performance of Li metal battery. Li could beuniformly plated inside the lithiophilic CNT film in contrast to lithiophobic CNT film, whereit was plated unevenly on the surface. This Li plating behavior was reflected in the performanceof the full cell, in which LiFePO4 (LFP) was used as a cathode. The full cell (LFP∥lithiophilic CNT film) exhibited remarkable cyclability owing to uniform Li plating insidelithiophilic CNT film.
