Abstract
Current collector (CC) is an indispensable constituent in lithium-ion battery (LIB). It plays an important role in supporting electrode materials and conducting electrons between the electrode materials and the external circuit. However, the density of metal CC is high and it hinders the lightweight development of LIB. In this work, lightweight three-dimensional (3D) CC was designed and prepared via a facile electroless plating method. The 3D copper-plated polyimide CC has a low areal density. The 3D structure of Cu-PI CC 2 can facilitate Li+ transfer between electrode materials and electrolyte owing to electrolyte can permeate through electrode. Moreover, the lithium titanate anode assembled with the 3D copper-plated polyimide Cu-PI CC 2 exhibited enhanced cycling and rate performance.
集流体（CC）是锂离子电池（LIB）中不可或缺的组成部分。它在支撑电极材料以及在电极材料和外部电路之间传导电子方面发挥着重要作用。然而，金属 CC 的密度较高，阻碍了锂离子电池的轻量化发展。本研究采用简便的无电解电镀法设计并制备了轻质三维（3D）CC。三维镀铜聚酰亚胺 CC 的面积密度较低。Cu-PI CC 2 的三维结构可以促进锂+在电极材料和电解液之间的转移，因为电解液可以通过电极渗透。此外，用三维镀铜聚酰亚胺 Cu-PI CC 2 组装的钛酸锂阳极显示出更高的循环和速率性能。
期刊介绍：
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
