“…[49] For example, a threedimensional (3D) free-standing CNT anode has been employed to fabricate a flexible LIB. [52] First, CNTs are grown on a Cu substrate via catalytic thermal CVD, and then transferred onto a graphenepolyethylene terephthalate film at 90°C by a thermal lamination process for preparing the flexible anode. The obtained 3D free-standing CNT anode shows an improved areal capacity (0.25 mAh cm -2 ).…”

The rapid development of flexible electronics has triggered extensive efforts to explore matching flexible energy-storage devices as power sources. Flexible lithium-ion batteries (LIBs) have been demonstrated as the current most attractive and versatile energy storage devices for flexible electronics. A series of designs and constructions for flexible LIBs have been investigated in recent years. Particularly, significant progress has been achieved in finding high performance electrolyte and electrode materials, new structural designs as well as suitable fabrication methods for flexible LIBs. In this review, the recent advances in the exploration of flexible lithium-ion batteries are summarized and discussed, with special focus on the selectivity of flexible electrode/electrolyte materials, cell structure design, and full cell assembly process. Perspectives for the future development of flexible LIBs are also discussed.Received: ((will be filled in by the editorial staff))Revised: ((will be filled in by the editorial staff))

“…Carbon-based materials with high conductivity were highly desirable for high-performance LIBs. Many studies have proved that CNTs can improve the electronic conductivity of electrode and offer the buffer spaces for the volume expansion of active material during the cycling process (Chen et al, 2007; Fu et al, 2013; Kang et al, 2016). Thanks to the graphitic structure and good electrical conductivity, CNTs has the capability of forming conductive network structure and is very suitable for preparing self-supporting film electrodes (Bai et al, 2015; Wan et al, 2015).…”

Rapidly-growing demand for wearable and flexible devices is boosting the development of flexible lithium ion batteries (LIBs). The exploitation of flexible electrodes with high mechanical properties and superior electrochemical performances has been a key challenge for the rapid practical application of flexible LIBs. Herein, a flexible composite electrode was prepared from the mixed solutions of Li[Li 0.2 Ni 0.13 Co 0.13 Mn 0.54 ]O 2 (LLOs), carbon nanotubes(CNTs), and nanofibrillated celluloses (NFCs) via a vacuum filtration method. The resulting LLOs/CNTs/NFCs electrode delivered an initial discharge capacity of 253 mAh g −1 at 0.1 C in the voltage range from 2.0 to 4.6 V, and retained a reversible capacity of 178 mAh g −1 with 83% capacity retention after 100 cycles at 1 C. The LLOs/CNTs/NFCs electrode exhibited excellent flexibility along with repeated bending in the bending test. The LLOs/CNTs/NFCs electrode after bending test remained a discharge capacity of 149 mAh g −1 after 100 cycles at 1 C, and the corresponding capacity retentions was 76%. The excellent electrochemical performance and high flexibility can be ascribed to the framework formed by CNTs with high conductivity and NFCs with good mechanical properties. The results imply that the as-fabricated electrode can be a promising candidate for the flexible LIBs.

“…Furthermore, on the way towards flexible batteries, freestanding CNTs electrodes have been reported by several groups [10][11][12][13]. Such electrodes are binder and additive-free, thus lowering the amount of inactive mass [14].…”

In this paper, we report the preparation of a flexible, self-standing and binder-free carbon nanotubes (CNTs) electrode with an electro-generated current collector. The copper current collector layer was electrodeposited on the backside of CNTs selfstanding film obtained by a simple filtration process. The obtained CNTs-Cu assembly was used as a negative electrode in Li-ion batteries exhibiting good performance along with proving its applicability in flexible batteries.
