Effect of carbon types on the electrochemical properties of negative electrodes for Li-ion capacitors

Electrode Materials, Electrolytes, and Challenges in Nonaqueous Lithium‐Ion Capacitors

“…Amorphous carbon not only has the advantage of outperforming graphite at higher rates, but also displays a higher capacity retention for long‐term cycling. However, amorphous carbon has a higher initial irreversible capacity loss compared to graphite …”

Pre-lithiation design and lithium ion intercalation plateaus utilization of mesocarbon microbeads anode for lithium-ion capacitors

“…The energy characteristics of LIC depend on the charge adsorption-desorption behavior of the AC positive electrode. The lithium ion intercalation/ de-intercalation reaction at the negative electrode is much slower than the adsorption/desorption reaction on the surface of the positive electrode, the power performance of LIC is determined by the rate capability of the negative electrode [16,17]. Therefore, the choice of positive electrode and negative electrode materials plays an important role in achieving high performance of LIC devices.…”

Hard carbon enveloped with graphene networks as lithium ion battery anode

“…Hard carbon (HC) has been demonstrated to be one of the most promising anode materials for Li-ion batteries due to its high theoretical capacity (740 mAh g À 1 ), which is expected to meet the requirements of future energy storage systems [1][2][3]. Unfortunately, due to considerable hetero atoms or radicals in hard carbon, absorbed species and formation of solid electrolyte interphase (SEI) on the active material surface, the irreversible capacity is commonly too high ( 4150 mAh g À 1 ) during the first lithium ion insertion/extraction.…”
