Graphite is an excellent negative electrode (anode) material for Li-ion batteries. It has high
specific capacity (eg,∼ 2.5× higher than LiCoO 2), high volumetric capacity (∼ the same as …

Increasing demand for sustainable battery technologies has necessitated substantive global
research efforts towards delivering improvements in terms of both, the underlying battery …

The movement of lithium ions into and out of electrodes is central to the operation of lithium-
ion batteries. Although this process has been extensively studied at the device level, it …

Cracking of electrodes caused by large volume change and the associated lithium diffusion-
induced stress during electrochemical cycling is one of the main reasons for the short cycle …

We examine the effects of surface tension and surface modulus on diffusion-induced
stresses within spherical nanoparticles. We show that both the magnitude and distribution of …

Although lithium-ion batteries are ubiquitous in portable electronics, increased charge rate
and discharge power are required for more demanding applications such as electric …

A lithium polyacrylate (Li-PAA) binder has been developed by 3M Company that is useful
with electrodes comprising alloy anode materials. This binder was used to prepare …

Electrochemical insertion-deintercalation reactions are typically associated with significant
change in molar volume of the host compound. This strong coupling between ionic currents …

Graphite has been used as the negative electrode in lithium‐ion batteries for more than a
decade. To attain higher energy density batteries, silicon and tin, which can alloy reversibly …

We derive and implement analytic solutions for the description of insertion particles subject
to cyclic surface concentration variations consistent with a periodic voltage excitation source …
