In particular, the hydrogen storage density of a type IV hydrogen tank can exceed the limit of 5 wt% [5, 11]. However, the hydrogen storage density still fails to break through the limit of 7.5 wt% due to the performance of the plastic liner material has not been fully exploited, even if the hydrogen storage pressure is increased [12, 13].
