Benefits of technology

This technology allows for better control over the structure of carbon nano tubules (CNT) by applying pressure before they leave their reactor vessel without losing them altogether. By doing this, the CNT's internal structures become stronger with fewer defect sites compared to traditional methods like sintering. Additionally, the method prevents damage caused by excessive heat while still allowing the CNTS to absorb moisture vapor into its inner volume. Overall, this new technique enhances the quality of batteries made up entirely of CNG materials.

Problems solved by technology

This patented problem addressed in the patents relates to developing a thin film battery technology suitable for applications where flexibility or durability needs to occur over time without compromising electrical properties like charge capacity and discharge rate capabilities. Current methods involve adding extra components into the battery cells themselves which makes them expensive and bulky. Additionally, existing solutions cannot handle environmental factors such as changing conditions during manufacturing processes.

Abstract

The invention discloses a flexible lithium-ion battery capable of working around the clock and a preparation method thereof. According to the battery, a membrane assembled by a stretched carbon nanotube macroscopic tube continuous body is taken as a current collector for positive and negative electrodes; and the membrane is subjected to porous treatment and electrolyte infiltration treatment in the membrane-forming process and an electrolyte can be stored into a carbon nanotube membrane as the current collector, so that the obtained battery still can normally work in harsh environments, such as extremely high temperature, extremely low temperature, vacuum and water. A battery main body comprises a positive electrode plate, a membrane and a negative electrode plate which are sequentially stacked. The invention further provides a preparation method of the battery. According to the flexible lithium-ion battery, the problem of a failure of an existing lithium-ion battery due to the fact that the current collector cannot store the electrolyte in the harsh environments can be effectively solved; the preparation process is in full integration with a production technology of an existing mainstream lithium-ion battery; mass production under existing production conditions is facilitated; and the flexible lithium-ion battery has very high practicability.
