Structural and interface design of hierarchical porous carbon derived from soybeans as anode materials for potassium-ion batteries

Insights into the diverse precursor-based micro-spherical hard carbons as anode materials for sodium–ion and potassium–ion batteries

“…The ex-situ Raman spectra were done to verify the mixed K-ion storage mechanism, as shown in Figure 4a. The charge-discharge curve of the first cycle is illustrated in 93 was similar to the report by J. Hu et al 84 and truly justified the mixed intercalation and adsorption mechanism.…”

Potassium-ion batteries: outlook on present and future technologies

“…Most plants including trees, crops, and vegetables are also appropriate carbon sources for electrochemical energy storage, due to their abundance and environmental friendliness. Liu et al 183 prepared a hierarchical porous hard carbon by using the low-cost and abundant soybeans as raw material. Benefiting from the medium surface area, low degree of graphitization, and large interplanar spacing, the obtained hard carbon electrode exhibits a high discharge capacity of 225 mAh g -1 at 40 mA g -1 and impressive cycling stability of 900 cycles.…”

Growth Mechanism of Micro/Nano Metal Dendrites and Cumulative Strategies for Countering Its Impacts in Metal Ion Batteries: A Review

“…For better coulombic efficiency, a tinny film of aluminum oxide was kept on the hard carbon surface. Mxenes and plastic wastes have greater recycling viability and utilization potential for energy storage in the coming years [461][462][463][464][465]. Likewise, battery recycling may improve the secondary life with reduced material requirements in batteries.…”
