Research On Flexible Energy Storage Device Based On Fiber Manganese Dioxide Electrode

In recent years,with the rapid development of science and technology,people’s living standards are increasing and a large number of intelligent wearable devices have emerged.However,the energy system of traditional wearable devices is generally poor in flexibility,heavy in weight,large in volume and poor in wear experience,which greatly limits the development of intelligent wearable devices.As an important excessive metal oxide,manganese dioxide has been widely concerned in the field of energy storage materials.The synthesis of high energy storage manganese dioxide and the potential application of nanoscale manganese dioxide have become a research hotspot.The main contents of this paper include the following parts:Therefore,in order to assemble rechargeable flexible fiber zinc manganese dioxide battery,we first explore the method of electrode assembly on high curvature interface.Based on the different methods of manganese dioxide synthesis,nanomaterials were prepared by hydrothermal synthesis method,and the electrodes were assembled through physical way.We also assembled flexible fiber electrode by a electrodeposition method.After comparison,hydrothermal synthesis method was used to prepare nanomaterials,and the diameter of 0.16 mm manganese dioxide flexible fiber electrode was successfully assembled.Furthermore,we optimized the zinc electrode and electrolyte.Then we successfully assembled a light weight,good flexibility,the diameter is only 2mm the full carbon rechargeable fiber flexible zinc manganese dioxide battery.The battery capacity can reach 165mAh/g at 0.5C.Then,we designed and built a new type of weaving equipment.Through a shuttle-flying weaving method,we successfully fabricated a flexible energy storage module with the power density at 0.16mW/cm2.Finally,combining the dye-sensitized solar cell module and energy storage module,we assembled a new kind of hybrid energy textile which could continuously provide energy for small electronic devices.This hybrid energy textile provides a new idea for assembling energy system of wearable electronic devices.
