Si is a promising anode material for Li ion batteries because of its high specific capacity, abundant reserve, and low cost. However, its rate performance and cycling stability are poor due to the severe particle pulverization during the lithiation/delithiation process. The high stress induced by the Li concentration gradient and anisotropic …

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a …
If the battery voltage is great enough to overcome the junction potential (0.6V in Si), the N-type electrons and P-holes combine annihilating each other. This frees up space within the lattice for more carriers to flow toward the junction. Thus, currents of N-type and

Sodium-ion battery development took place in the 1970s and early 1980s. However, by the 1990s, lithium-ion batteries had demonstrated more commercial promise, causing interest in sodium-ion batteries to decline. [10] [11] In the early 2010s, sodium-ion batteries experienced a resurgence, driven largely by the increasing cost of lithium-ion battery raw …

In this research, we examine the effect of light irradiation on electrochemical lithiation by utilizing the doping type (p- and n-type) of Si single-crystals in a lithium-ion battery system. Ionic liquid containing lithium bis (fluorosulfonyl) imide (LiFSI) dissolved in N -methyl- N -propylpyrrolidinium bis (fluorosulfonyl) imide was used as the electrolyte.
In the early days of solar PV production, much of the demand came from space agencies for satellites and manned space exploration. It turns out p-type Si is far more resistant to the degradation from cosmic array. This demand set the tone of the industry and p-type Si solar cells came to dominate the residential and commercial solar markets globally. Recently, …

Lithium–silicon batteries are lithium-ion battery that employ a silicon-based anode and lithium ions as the charge carriers. Silicon based materials generally have a much larger specific capacity, for example 3600 mAh/g for pristine silicon, relative to the standard anode material graphite, which is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC6. Silicon''s large volume change (approximately 400% based on crystallographic densities) when li…
