Reactivity and Safety Aspects of Carbonaceous Anodes used in Lithium-Ion Batteries — Correlation of Structural Parameters and Reactivity

摘要: Among various alternative anode materials for rechargeable batteries, the carbonaceous anodes are most promising as their capacity and rate capabilities can be tailored to satisfy specific applications [1–4]. Lithium intercalated into a large variety of materials’. Graphite with high degree crystallinity appears desirable candidate due host (Li/C6), low flat electrode potential profile similar that Li metal (0.01–0.02 V). The electrochemical process lithium insertion extraction from graphitic electrodes, however, has at least two major problems: first, excessive electrolyte decomposition during first lithiation causing irreversible loss, second, formation gaseous species which detrimental performance cells considered hazardous majority flammable [5, 6]. Some may also dissolve in organic participate parasitic reactions within operating voltage Li-ion cells.
