As like other battery cell systems, a classical LIB cell is composed of a negative electrode (N) and a positive electrode (P), which are mechanically separated by an electrolyte-wetted separator [12].This two-electrode configuration is typically termed as "full-cell setup" in battery research (as depicted in Fig. 1 (d)), in which the cell voltage, …
Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious …

Graphite and related carbonaceous materials can reversibly intercalate metal atoms to store electrochemical energy in batteries. 29, 64, 99-101 Graphite, the main negative …
For nearly two decades, different types of graphitized carbons have been used as the negative electrode in secondary lithium-ion batteries for modern-day energy storage. 1 The advantage of using carbon is due to the ability to intercalate lithium ions at a very low electrode potential, close to that of the metallic lithium electrode (−3.045 V vs. …
In the context of batteries, a nanostructured electrode contains active material particles in the size range 1–100 nm, whereas a microstructured electrode uses …
