Summary
IMDEA Materials and IMDEA Energy Institutes have developed a laminar composite material simultaneously having excellent structural properties and high energy storage efficiency. The combinations of these properties enable using this multifunctional composite material as a structural component in the automotive and aeronautics fields, in portable electric and/or electronic devices, microelectronics, robotics, tools, energy generating systems (wind energy generating systems, photovoltaic energy generating systems, etc.), coupled to batteries, in cranes and construction equipment, in the textile/footwear industry, in home appliances.
Description
This innovative composite material is based on a polymer electrolyte arranged between carbon nanotube fiber sheets as interleaves, which in turn are interleaved between outer sheets having mechanical strength properties, forming together a laminated composite structure.
The internal structure formed by the polymer electrolyte arranged between carbon nanotube fiber sheets provides high energy storage capacity to the material, while at the same time allows improving adhesion between sheets and material toughness, as well as resistance to delamination. Said internal structure therefore allows replacing the webs or thin interleaves between structural sheets used in the state of the art, while also incorporating an additional functionality in the composite material.
Advantages and innovations
- Laminar composite material simultaneously having excellent structural properties and high energy storage efficiency. The combinations of these properties enable using this multifunctional composite material as a structural component in different applications.
- Excellent structural properties: shear modulus of 895 MPa, flexural modulus of 60 GPa and a flexural strength of 153 MPa.
- High energy storage efficiency: Operation at 1 – 3 V, long cycling > 10000.
- Cost-effective manufacturing: Compatible with roll-to-roll.
- Safety: Non-flamable (LOI 42)
