Lithium metal has been considered as an ultimate anode choice for next-generation secondary batteries due to its low density, superhigh theoretical specific capacity and the lowest voltage potential. Nevertheless, uncontrollable dendrite growth and consequently large volume change during stripping/plating cycles can cause unsatisfied operation efficiency and …
Rechargeable batteries Li-ion batteries are now used in very high volumes in a number of relatively new applications, such as in mobile phones, laptops, cameras and many other consumer products. The typical Li-ion cells use carbon as the anode and LiCoO 2 or LiMn 2 O 4 as the cathode. as the cathode.

Introduction Current lithium-ion batteries, which rely on intercalation chemistry, have nearly attained their theoretical energy density of approximately 250 Wh kg −1. 1 However, the demand for even higher energy density, such as 500 Wh kg −1, remains persistent, particularly for electric vehicles and aircraft. 2 One potential approach to achieve this goal involves replacing graphite …
The clean energy revolution requires a lot of batteries. While lithium-ion dominates today, researchers are on a quest for better materials.
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 longer …
A high concentration lithium salt in electrolytes has recently attracted attention to improve the performance of rechargeable lithium–oxygen (Li–O2) batteries. In particular, lithium nitrate (LiNO3) was noted as a promising salt for Li–O2 batteries because of its catalytic effect during the charge process. N
The main components and, most notably, the concentration of the non-aqueous electrolyte solution have not significantly changed since the commercialization of Li-ion batteries in the early 1990s
The voltage generated by the battery at a given state of charge can be calculated using the Nernst equation and depends mainly on the concentration of Li-ions on the electrodes. The more Li-ions migrate to the cathode side, the higher their concentration at the cathode and the cell voltage drops accordingly.
Using these two techniques, we show that a Li concentration gradient evolves during cycling, and the depth of the gradient expands proportionally with the number of cycles.

The solid electrolyte interphase (SEI) significantly influences the electrochemical performance of lithium-ion batteries. Traditional electrolytes, particularly ether electrolytes, make it challenging to form a stable SEI film, and the corresponding lithium-ion batteries frequently exhibit poor electrochemical performance. In this paper, we develop a stable SEI film to improve fast …
In recent years, the production of lithium from spodumene has gained importance (I) as its price and application in batteries has increased and (II) as an additional source of tantalum, a scarce metal with high economic …
Lithium-ion batteries operate by collecting current and directing it into the battery during the charging process. Typically, a graphite anode attracts lithium ions and retains them as a charge. During discharge, the cathode draws the stored lithium ions and channels them to another current collector.
Lithium-ion batteries use lithium ions to create an electrical potential between the positive and negative sides of the battery, known as the electrodes. A thin layer of insulating material called a "separator" sits between …
