A Structural Battery and its Multifunctional Performance

Abstract

Electric Vehicles In article number http://doi.wiley.com/10.1002/aesr.202000093 by Leif E. Asp and co‐workers, renewable electrical energy stored in the body‐in‐white and interior panels of future electric cars. Structural batteries made from carbon fiber‐reinforced composites reduce vehicle weight to increase efficiency and driving range.

An All-Solid-State Coaxial Structural Battery Using Sodium-Based Electrolyte

“…The coated and uncoated fibers were then integrated as reinforcement in a biphasic polymeric resin impregnated with a liquid electrolyte to guarantee the electrochemical properties. This new concept of electrolyte, in which the liquid electrolyte is an ionic liquid, named structural battery electrolyte [21,22], was employed to manufacture the prototypes of a full multifunctional power composite cell [23] with remarkable malfunction properties while showing reduced specific energy.…”

“…It is highlighted that, because of this battery design, the CFRP outer cylinder shell can be independently cured with one of the electrodes in compliance with the material supplier recommendation without mining the cell mechanical performance, even in the case of high temperature curing cycles. This aspect, as shown in the recent literature, places relevant limitations in the integration of battery components with high-performance CFRP structures since it forces the use of low-temperature curing cycle resins and adhesives [14,24] or the filling of the cured composite with liquid electrolyte that must be carried out in a glovebox with safety concerns and limitations of the structural dimensions [16,23,26]. It is highlighted that, because of this battery design, the CFRP outer cylinder shell can be independently cured with one of the electrodes in compliance with the material supplier recommendation without mining the cell mechanical performance, even in the case of high temperature curing cycles.…”

Block Copolymer Derived Porous Carbon Fiber: An Emerging Structural Functional Material

“…Third, a critical feature of fibers is mechanical flexibility. Fibers can be bent to any shape and geometry, allowing for knitting and weaving into complex structures. , Using carbon fibers as a flexible energy storage platform , can innovate the future of structural–functional materials . One concern of the porous carbon fibers is the potentially weakened overall mechanical strength.…”
