This property can lead to the diffusion of gases through the material, potentially causing electrolyte loss or contamination in sealed systems. Such gas permeation can significantly reduce the lifespan and efficiency of EES devices, particularly in long-term storage scenarios.

Furthermore, PC's limited resistance to certain organic solvents poses challenges in EES applications where such solvents are present. This vulnerability can lead to material swelling, cracking, or dissolution, compromising the structural integrity of the storage system. The potential for stress cracking under load in the presence of certain chemicals is another concern that limits PC's applicability in some EES designs.

Recycling and end-of-life management of PC in EES systems present additional challenges. The complex nature of EES devices often makes it difficult to separate and recycle PC components effectively, raising environmental concerns and potentially increasing the overall cost of EES solutions that utilize this material.

Lastly, while PC offers good impact resistance, its scratch resistance is relatively low compared to some alternative materials. In EES applications where surface integrity is crucial for maintaining insulation properties or preventing contamination, this limitation can be significant. Improving PC's scratch resistance without compromising its other beneficial properties remains a challenge for material scientists and engineers working on EES solutions.
