柔性室温液态金属电池的3D打印
3D Printing of Flexible Room-Temperature Liquid Metal Battery
摘要：
提出并实验验证了基于3D混合打印的完全柔软且可变形的室温液态金属电池。分别采用液态金属镓和导电凝胶作为负极和正极材料。阐明了单电池和多电池不同结构电池的放电过程。结果表明，该电池具有较好的稳定性和持续放电性能，但多节电池的放电性能随时间呈阶梯状下降。通过SEM和EDS观察了电极在放电过程中的形貌变化，发现碱性电解液对氧化镓的溶解性使液态金属易于暴露并具有活性。成功的3D混合打印允许不同的聚合物，包括PLA，ABS和TPU，在任何所需的电池主体结构中精确地图案化，并在适当的指定位置上具有液体电极。通过工作装置说明了新一代蓄电池的灵活性和实用性。目前的软电池为未来的可穿戴和表皮电子产品提供了重要的电源。
英文摘要：
The entirely soft and transformable room-temperature liquid metal battery based on 3D hybrid printing was proposed and experimentally demonstrated. Liquid metal gallium and conductive gel were employed as the negative and positive electrode material, respectively. The discharge process of batteries with different structure, single-cell and multi-cell, were clarified. The results indicated that the obtained battery possessed rather stable and persisted discharge property, but the multi-cell battery presented stair-step decrease overtime. SEM and EDS images were obtained to evaluate the morphological change of the electrode during the discharge process, and the liquid metal was found to be easily exposed and active according to the solubility of the alkaline electrolyte to oxidized gallium. The successful 3D hybrid printing allowed different polymers, including PLA, ABS and TPU, to be precisely patterned in any required battery body structures, with liquid electrodes in appropriate specified positions. The flexibility and practicability of this new generation battery was illustrated through working devices. The present soft battery offers important power supply for future wearable and epidermal electronics.
