We report on the two families of carbon materials (graphites and hard carbons) known to be the most attractive host structures in Li-ion batteries. Both present drawbacks related to the irreversible capacity. For graphites, it is due to exfoliation, which can be suppressed by the presence of...
In this work, these tradeoffs are overcome by fabricating hybrid anodes with uniform mixtures of graphite and hard carbon, using industrially‐relevant multi﹍ayer pouch cells (>1 Ah) and electrode loadings (3 mAh cm). By controlling the graphite/hard carbon ratio, this study shows that battery...
Hard carbonshave a high degree of disorder and cannot be graphitized. Their capacity varies widely, depending on the degree and type of disorder. Some hard carbons are known for their good cycling stability; however, their capacity is below that of graphite. Their potential is more positive than...

graphite anode in LIBs is not suitable for SIBs because of the positive formation energy of Na-graphite intercalation compounds (Na-GIC) [9]. Compared with alloy- and conversion-based anode materials with high plateau voltage and poor cycling stability [10,11,12,13,14,15], hard carbon has ...
3b. The mechanism that Li-ion inserts in hard carbon material is different from that in graphite material. Though hard carbon is not as fully crystallized as graphite, there is a larger inter-layer space structure in hard carbon. The behavior of Li-ion insertion in hard carbon is determined...
FEC or VC have been widely employed as additives to enhance the ICE of the graphite anode in lithium-ion batteries, but it does not work for the HC carbon anode in SIBs. Ponrouch et al. [35]. proposed a fluoroethylene carbonate (FEC)-containing electrolyte based on EC and PC as ...
