A stretchable Li4Ti5O12 anode and a LiFePO4 cathode with 80% stretchability are prepared using a 3D interconnected porous polydimethylsiloxane sponge based on sugar cubes. 82% and 91% capacity retention for anode and cathode are achieved after 500 stretch–release cycles. Slight capacity decay of 6% in the battery using the electrode in stretched state is observed.

可伸缩锂离子电池的3D多孔海绵启发电极

使用基于方糖的3D互连多孔聚二甲基硅氧烷海绵制备具有80%拉伸性的可拉伸Li 4 Ti 5 O 12阳极和LiFePO 4阴极。经过500次拉伸释放循环,阳极和阴极的容量保持率分别达到82%和91%。在使用处于拉伸状态的电极的电池中,观察到轻微的容量衰减6%。
