As emerging the new electric devices, the commercial lithium ion batteries have
faced with various challenges. In this regard, many efforts to solve challenges have been tried.
In order to solve the above problems in terms of development of a new secondary battery,
we successfully demonstrated the two electrocatalysts, such as MCWB and PPY hydrogel, PPY
hydrogel and MCWB showed typical H3-type BET isotherm, indicating that micro- and mesopores
existed. Especially, in terms of voltage efficiency at the first cycle, PPY hydrogel was
higher than that of MCWB, but lower than that of PtC. More interestingly, the PPY hygrogel
based seawater battery exhibited charge-discharge reversibility during 20 cycles, and the voltage
efficiencies ranged from 70.32 % to 77.35 % in cyclic performance test.
