Dicarboxylate CaC8H4O4 as a high-performance anode for Li-ion batteries

引用

Nano Research 2015年第2期8卷 523-532页

作者： Liping Wang Haiquan Zhang Chengxu Mou Qianling Cui Qijiu Deng Jing Xue Xinyi Dai jingze Li State Key Laboratory of Electronic Thin Films and Integrated Devices School of Microelectronics and Solid-State Electronics University of Electronic Science and Technology of China Chengdu 610054 China School of Materials Science and Engineering University of Science and Technology Beijing Beijing 100083 China

Currently, many organic materials are being considered as electrode materials and display good electrochemical behavior. However, the most critical issues related to the wide use of organic electrodes are their low thermal stability and poor cycling performance due to their high solubility in electrolytes. Focusing on one of the most conventional carboxylate organic materials, namely lithium terephthalate Li2CsH4O4, we tackle these typical disadvantages via modifying its molecular structure by cation substitution. CaCsH4O4 and A12（C8H4O4）3 are prepared via a facile cation exchange reaction. Of these, CaCsH4O4 presents the best cycling performance with thermal stability up to 570℃ and capacity of 399 mA.h.g-1, without any capacity decay in the voltage window of 0.005-3.0 V. The molecular, crystal structure, and morphology of CaCsH4O4 are retained during cycling. This cation-substitution strategy brings new perspectives in the synthesis of new materials as well as broadening the applications of organic materials in Li/Na-ion batteries.

Constructing a three-dimensional(3D)multifunctional hosting architecture and subsequent thermal infusion of molten Li to produce advanced Li composite is an effective strategy for stable Li metal ***,the pure liquid Li is difficult to spread across the surface of various substrates due to its large surface tension and poor wettability,hindering the production and application of Li composite ***,heteroatomic Ca is doped into molten Li to generate Li-Ca alloy,which greatly regulates the surface tension of the molten alloy and improves the wettability against carbon cloth(CC).Moreover,a secondary network composed of CaLi2 intermetallic compound with interconnected ant-nest-like lithiophilic channels is in situ formed and across the primary scaffold of CC matrix by infiltrating molten Li-Ca alloy into CC and then cooling treatment(LCAC),which has a larger and lithiophilic surface to enable uniform Li deposition into interior space of the hybrid scaffold without Li ***,LCAC exhibits a long-term lifespan for 1100 h under a current density of 5 mA cm^(-2)with fixed areal capacity of 5 mAh cm^(-2).Remarkably,full cells paired with practical-level LiFePO4 cathode of 2.45 mAh cm^(-2)deliver superior performance.
