Is silicon a promising anode material for high-performance lithium-ion batteries (LIBs)?

Owing to highly theoretical capacity of 3579 mAh/g for lithium-ion storage at ambient temperature, silicon (Si) becomes a promising anode material of high-performance lithium-ion batteries (LIBs).

How does a pristine Si layer affect crystallinity?

The pristine Si layer provided a large and clear Si crystallite phase with high crystallinity (Fig. 4c). However, as the amount of crystal growth inhibitor increased, the size of the Si crystals substantially decreased in the C (1.5)Si layer with the emergence of the SiC phase (Fig. 4d).

How many atoms are in a C(X)Si slab model?

The C (x)Si slab model (x = 0, 1.5, 5) consists of three layers of graphene and a mixture of silane (159 molecules) and ethylene (0, 26 and 91 molecules for the three systems, respectively). Carbon, hydrogen and silicon atoms are coloured in grey, white and yellow, respectively. b, The number of Si atoms in the largest atom cluster over time.

Could a synthetic anode improve the durability of lithium ion batteries?

A research team, affiliated with UNIST has developed a novel synthetic approach that could dramatically improve the durability of silicon (Si)-based anode materials that are regarded as high capacity anodes for next generation lithium ion batteries (LIBs).
