Prolate carbon architecture as a novel Li-ion battery anode with kinetic study

Lithium-ion battery (LIB) performance can be tailored by controlling the structure, texture, defects, dopants, and architecture of carbon-based anodes. In this publication, a novel prolate carbon-shape with dual short-ordered graphite-like and turbostratic arrangements was studied for the first time in LIB anodes which delivered a promising reversible capacity of 271 mAh g(-1) at 100 mA g(-1) after 100 cycles. The novel prolate carbon was synthesized by dry autoclaving avocado oil, utilizing autogenic pressure to ensure a homogeneous sample. The novel prolate carbon demonstrated stable, promising performance by leveraging graphite-like layers towards the surface and a highly amorphous bulk. Physico-chemical and extensive electrochemical studies were conducted to elucidate the Li-ion storage mechanism of the novel architecture: the anode was found to rely on 70% of its lithium to be stored via capacitance, and its apparent lithium-ion diffusion coefficients were estimated in the range between 10(-9) and 10(-12) cm(2) s(-1).
