As with traditional rigid Li-ion batteries, electrodes play a crucial role in the battery’s capacity, energy density, and power density. Choosing electrode materials and cell structure is the key to achieving a high-performance flexible battery.
The research in high performance flexible lithium ion batteries (FLIBs) thrives with the increasing demand in novel flexible electronics such as wearable devices and implantable medical kits. FLIBs share the same working mechanism with traditional LIBs. Meanwhile, FLIBs need to exhibit flexibility and even bendable and stretchable features.
Wang et al. fabricated adhesive-free composite electrodes (LTO@CFC) for flexible Li-ion batteries by growing arrays of active material spinel lithium titanate (LTO) orthorhombic on flexible carbon fiber cloth (CFC) (Figure 6 a).
We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries.
The performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
(i) The flexible electrode is an essential part of flexible batteries, and their roles contain transporting electrons, providing electrode reaction interfaces, supporting battery structures, and realizing flexible properties. The flexible electrode material has a decisive influence on the battery's energy density, rate performance, and flexibility.
