| Cost |
The increase of industrial scale production devices reduces the price of nanofiber webs |
85–87
|
| Un-spinnability |
Using polymer mixture or using additives can help to fabricate nanofiber web |
88 and 89
|
| Defect-free surface |
Optimizing both system and process parameters is essential to prevent uneven web surface, which can lead to energy generation failure |
90–92
|
| Low conductivity |
The conductivity can be improved by using conductive polymers, carbon nanofibers, or additives |
32 and 93–95
|
| Biocompatibility |
Focusing on biocompatible polymers and using non-toxic chemicals can be the solution |
96–98
|
| Stability |
Using chemical resistance nanofiber webs such as PVDF or PSU are beneficial to enhance stability and durability under acidic and alkaline conditions |
