| Popis: | Advanced electrode materials with bendability and stretchability are critical for the rapid development of fully flexible/stretchable lithium-ion batteries. However, the sufficiently stretchable lithium-ion battery is still underdeveloped that is one of the biggest challenges preventing from realizing fully deformable power sources. Here, a low-temperature hydrothermal synthesis of a cathode material for stretchable lithium-ion battery is reported by the in situ growth of LiMn2O4 (LMO) nanocrystals inside 3D carbon nanotube (CNT) film networks. The LMO/CNT film composite has demonstrated the chemical bonding between the LMO active materials and CNT scaffolds, which is the most important characteristic of the stretchable electrodes. When coupled with a wrinkled MnOx/CNT film anode, a binder-free, all-manganese-based stretchable full battery cell is assembled which delivers a high average specific capacity of ≈97 mA h g−1 and stabilizes after over 300 cycles with an enormous strain of 100%. Furthermore, combining with other merits such as low cost, natural abundance, and environmentally friendly, the all-manganese design is expected to accelerate the practical applications of stretchable lithium-ion batteries for fully flexible and biomedical electronics. |
