[PDF Version]Side reactions that occur in LIBs during overcharging include the oxidative and reductive decomposition of the electrolyte components [,, ], irreversible degradation of the positive and negative electrode materials by electrolyte decomposition residuals, and lithium metal plating at the negative electrode.
The number of side reactions increased with the temperature, and a substantial rise was observed at 100 °C, consistent with the operando analysis findings from XRD and XAFS measurements. However, the lithium-plating side reaction at the negative electrode during overcharging at 30 °C was not evident as a side reaction in Fig. 6.
Utilizing the Co valence information derived from alterations in Co K-top energy, we could qualitatively discern the side reactions occurring at the positive electrode. The slope of the Co K-top energy change shifted within the overcharged region, corroborating the escalation of side reactions at the positive electrode with increasing temperatures.
Based on the operando XAFS measurements, the side reaction capacity of the positive electrode up to an SOC of 100% (C p_std) was determined to be 0 mA h at all temperatures.
Contact with lithium metal triggers chemical reactions, involving reduction and structural changes in the polymer electrolyte. The ionic conductivity of the reaction products is usually lower than that of the electrolyte, necessitating lower reductive reactivity of the polymer electrolyte.

The quest for new positive electrode materials for lithium-ion batteries with high energy density and low cost has seen major advances in intercalation compounds based on layered metal oxides, spin.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Electrons are simultaneously extracted from one electrode and injected into another electrode, storing and delivering electrical energy, during which materials are oxidized or reduced in positive and negative electrodes. Lithium ions shuttle between positive and negative electrodes, named lithium-ion (shuttlecock, swing, etc.) batteries.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
