Hi,

Whatever the electrode, the potential window for symmetric device is between 0 V to OER/ HER.

Meng Hu

I am wondering what the meaning of "symmetric" is.

Thus, I think it is possible for the EDLC-based electrode materials .

Zhenyu Yang

Yes. I also think it is possible for the EDLC-based electrode materials
