A commonly proposed structural battery is based on a carbon fiber reinforced polymer (CFRP) concept. Here, carbon fibers serve simultaneously as electrodes and structural reinforcement. The lamina is composed of carbon fibers that are embedded in a matrix material (e.g. a polymer).
In the structure of new energy vehicles, the power battery pack structure is the most important power component, thus, it needs to be designed with a safer and more reasonable structure to meet the requirements of shock resistance and durability.
Two main types of structural batteries can be distinguished: embedded batteries and laminated structural electrodes. Embedded batteries represent multifunctional structures where lithium-ion battery cells are efficiently embedded into a composite structure, and more often sandwich structures.
Currently, most structural battery studies are still in the early stage of concept demonstrations, and other passive components in real systems are rarely involved such as battery management systems and cooling systems.
Therefore, tuning current densities and matrix properties could optimize the battery design. They further demonstrated that a cross-ply lay-up structural battery would have different debonding behavior from a UD laminate battery, which still required experimental evidence .

In laminated structural electrodes the electrode material possesses an intrinsic load-bearing and energy storage function. Such batteries are also called massless batteries, since in theory vehicle body parts could also store energy thus not adding any additional weight to the vehicle as additional batteries would not be needed. An example for such batteries are those based on a zinc anode, manganeseoxide cathode and a fiber/ polymer composite electrolyte. The structural electrolyte
