Potato derived biomass porous carbon as anode for potassium ion batteries

Jute sticks derived novel graphitic porous carbon nanosheets as Li‐ion battery anode material with superior electrochemical properties

“…The narrow and broad diffraction peaks appear at 2θ = 25.9 o and 2θ = 43.4 o corresponds to the presence of (002) and (101) reflections of graphite (JCPDS card no. 41‐1487), respectively . The sharp and narrow (002) diffraction peak appears at 2θ = 25.9 o implies the high crystalline nature of carbon material developed in the present study.…”

“…The concern over the serious global environmental issues arising from usage of fossil fuels has driven researchers to look for alternative renewable energies to mitigate the current energy crisis . Electrical energy storage devices for electric vehicles, especially the rechargeable batteries have gained significant attention over the years due to their critical role in replacing and curbing pollution arising from burning of fossil fuels .…”

Advancements and Challenges in Potassium Ion Batteries: A Comprehensive Review

“…The N‐doped porous carbon derived from walnut septum could exhibit an initial specific capacity of 263.6 mAh g −1 at 0.1 A g −1 and a specific capacity of 119.9 mAh g −1 at the end of 1000 cycles at 1 A g −1 with a Coulombic efficiency of 55.1% . Potato derived biomass porous carbon could also demonstrate promising capacities of 248 mA h g −1 and 152 mA h g −1 at current densities of 100 mA g −1 and 1000 mA g −1 , respectively, with ≈100% capacity retention over 400 cycles at 500 mA g −1 having a Coulombic efficiency about 100% . The 2D MXenes (Ti 3 CNT z ) could exhibit a 1st discharge capacity of 710 mAh g −1 at 20 mA g −1 , but with a poor initial Coulombic efficiency of 28.4% .…”
