A mushroom derived biomass carbon as high-stability anode for potassium ion battery

An oriented tube array porous carbon anode prepared using a self-blowing mold of salt templates for high-rate potassium storage

“…In recent years, many efforts have been made to design anode materials for PIBs with excellent properties, including phosphide, 9,10 sulfide, [11][12][13][14][15] selenide, [16][17][18][19][20] and carbon materials. [21][22][23][24][25] Among them, carbon as a commonly used electrode material shows great potential in electrochemical energy storage due to its good electrical conductivity, high chemical stability, low price, and environmental friendliness. 23,26,27 Despite good progress, the poor kinetic behaviour and severe bulk effects (∼60%) limit the practical application of carbon materials in PIBs.…”

“…For example, Du et al prepared an N, S, and P co-doped porous carbon by direct carbonization of mushrooms with ordered channels. 24 Jiang et al prepared an N, O co-doped corn silkderived porous carbon through a facile hydrothermal method and one-step carbonization. 35 Although porous carbon with ordered pores or channels is being obtained by carbonizing biomass, these porous structures are not only highly reliant on the screening of biological structures easily affected by the growth environment, but also require the environmentally unfriendly removal of a large number of impurities that they contain.…”

Bimetallic-based composites for potassium-ion storage: challenges and perspectives

“…4 Unfortunately, lithium resources cannot meet the rapidly growing demand for LIBs. 5,6 Therefore, other new energy storage technologies to complement LIBs are urgently needed. 7,8 Supplement energy storage technologies based on other earth-abundant resources (Na, K, and Al) have emerged recently.…”
