Market Assessment: stretchable and wearable textile-based lithium-ion battery electrodes

新的“智能服装”系统将结合各种可穿戴电子设备，从检测生物特征数据的传感器到向用户显示数据的发光显示器。对于每一种应用，都需要车载和可穿戴电源来实现这些可穿戴设备的连续功能。将储能材料与纺织品集成面临的主要挑战是脆性硬储能材料和柔软可拉伸纺织品的机械性能之间的不匹配。我们已经证明了一种独特的策略来解决这个问题，通过使用经编天鹅绒织物在建筑应变工程设计，以准备可拉伸的纺织品为基础的锂离子电池（LIB）电极。丝绒织物能够将LIB电极集成到单片丝绒织物中，同时保护脆性电活性材料免受应变和随后的损坏。基于纺织品的可拉伸LIB电极即使在1000次重复拉伸循环后也表现出优异的电气和电化学性能，证明了基于纺织品的建筑应变工程设计的保护功能。该提案旨在评估这种新的可穿戴技术的市场机会，重点是个人防护设备，健康和保健以及时尚电子纺织品，最终目标是确定潜在的合作伙伴来开发该技术，以达到更高的技术准备水平。

New "smart clothing" systems will incorporate a variety of wearable electronic devices, from sensors to detect biometric data to light-emitting displays to display data to the user. For every application, on-board and wearable power sources are needed to enable the continuous function of these wearable devices. Integrating energy storage materials with textiles faces a main challenge of the mismatch between the mechanical properties of brittle, hard energy storage materials and soft, stretchable textiles. We have demonstrated a unique strategy to solve this problem by using a warp-knitted velour fabric in an architectural strain-engineering design to prepare stretchable textile-based lithium-ion battery (LIB) electrodes. The velour fabric enables the integration of the LIB electrode into a single piece of velour fabric, while protecting the brittle electroactive material from strain and subsequent damage. The textile-based stretchable LIB electrode exhibits excellent electrical and electrochemical performance even after 1000 repetitive stretching cycles, demonstrating the protective functionality of the textile-based architectural strain-engineering design. This proposal aims to assess market opportunities for this new wearable technology, with a focus on personal protective equipment, health and wellness, and fashion e-textiles, with an ultimate goal of identifying potential collaborative partners to develop the technology to reach a higher technology readiness level.
