WhatsAppBackground In 2010, the rechargeable lithium ion battery market reached ~$11 billion and continues to grow. 1 Current demand for lithium batteries is dominated by the portable electronics and power tool industries, but emerging automotive applications such as electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) are now claiming a share.
WhatsAppHighlights Real-time stress evolution in a practical lithium-ion electrode is reported for the first time. Upon electrolyte addition, the electrode rapidly develops compressive stress (ca. 1–2 MPa). During intercalation at a slow rate, compressive stress increases with SOC up to 10–12 MPa. De-intercalation at a slow rate results in a similar …

WhatsAppSilicon is a promising negative electrode material with a high specific capacity, which is desirable for commercial lithium-ion batteries. It is often blended with graphite to form a composite anode to extend lifetime, however, the electrochemical interactions between silicon and graphite have not been fully investigated.
WhatsAppFor example, when the local anode potential drops below 0 V vs Li/Li +, lithium plating occurs [11], [12], [13] which reduces the battery''s available energy capacity due to loss of lithium inventory. The formation of dendrites from plated lithium can lead to internal short-circuits [14], [15], [16] .
WhatsAppAbstract 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.
