This technology relates to flexible lithium secondary batteries with high energy density and can be applied to wearable devices. In particular, it is a technology designed to simultaneously enhance performance, durability, stability, and applicability based on a flexible electrode for a flexible lithium secondary battery, a method for manufacturing the same, and core materials, structures, processes, or device configurations related to a flexible lithium secondary battery having high energy density containing the same.
It aims to address the low energy density of existing flexible lithium secondary batteries by introducing a new electrode structure and manufacturing method. Accordingly, this technology applies a dangling electrode structure having high porosity and excellent flexibility as a core means and proposes a technical concept using fluorinated polyvinylidene polymers and conductive materials to create the porous electrode structure.
Accordingly, by introducing a new electrode structure and manufacturing method, this invention is expected to improve the energy density and flexibility of lithium secondary batteries, and simultaneously enhance reproducibility, scalability, and process suitability in actual usage environments. Furthermore, it can be utilized as a high-performance material, device, battery, sensor, apparatus, or manufacturing process in related industries, making it advantageous in terms of subsequent commercialization and demonstration deployment.
