Multifunctional Composite Laminate Based Structural Battery for Vehicle Applications

The company is innova2ng the next genera2on of mul2func2onal composite laminates designed to concurrently serve as both energy storage units and load-bearing components. This pioneering technology is crucial for advancing the electric vehicle sector, where the integra2on of a por2on of the structure for electrical energy storage aims to reduce vehicle weight, enhancing overall energy density and contribu2ng to the future sustainability of electric vehicles. Current efforts to improve electric vehicle range focus on advancing ba9ery chemistry, with lithium-ion, nearing its theore2cal limit, s2ll leading the field. However, endeavors to develop mul2func2onal energy-storing composites face hurdles due to the lack of a solid polymer electrolyte capable of providing both ionic conduc2vity and mechanical performance. This limita2on hampers the progress of lightweight and efficient electric vehicles. Overcoming this challenge is vital for pushing the boundaries of current technology and facilita2ng the broader adop2on of electric vehicles. In Phase I, the project aims to achieve a minimum energy density of 50 Wa9.hours/Kilogram by developing a mul2func2onal composite structure. This involves fine-tuning the integra2on of the solid polymer electrolyte, modified carbon fiber electrodes, and glass fiber separator to maximize energy storage capabili2es within the composite matrix. Simultaneously, maintaining 50% of the mechanical proper2es (tensile strength and modulus) compared to a structural epoxy matrix is crucial. This objec2ve emphasizes the need to strike a balance between structural integrity and energy storage capabili2es within the composite material. Addi2onally, a detailed cost and weight study will be conducted, offering insights into poten2al mass savings and economic viability when implemen2ng the innova2ve composite technology in specific parts or components.
