Despite the many potential applications of seawater batteries (SWBs), the limited performance of available materials has hindered their commercialization. Researchers in South Korea have developed a process called ‘plasma in liquid,’ which involves preparing a mixture of precursors containing carbon, N, and S and discharging plasma into the solution resulting in a material with high doping levels of N and S with a structural backbone of carbon black. Experimentally they have confirmed that the material showed great potential for SWBs. The co-doped anode material exhibited remarkable electrochemical performance in SWBs, with a cycling life of more than 1500 cycles at a current density of 10 A/g. They can be safely operated while completely submerged in seawater, used to supply emergency power in coastal nuclear power plants, installed on buoys to aid in navigation and fishing and installed as a power source in passenger ships…read more.
