Lithium-ion battery safety

Lithium-ion battery safety

Lithium-ion battery safety is not a simple topic. What are the risks when using lithium-ion batteries? How to prevent any safety issue? Risk linked to the use of a lithium-ion battery When submitted to increasing temperatures, whatever the chemistry, there is a...
From a lithium-ion cell to a battery system

From a lithium-ion cell to a battery system

The voltage of a single lithium-ion cell (3 to 4V) is too low to supply high power applications. Therefore, it is necessary to assemble cells together to elevate the voltage and be able to deliver sufficient power to the application. Cells are connected in series...
History and battery future

History and battery future

The battery future can only be studied with respect their historical development, as detailed by Jean-Marie Tarascon in this document and summed up here below: 1859: First lead acid battery by Gaston Planté. As indicated in the figure below, there is a material...
Li-Ion negative electrode technologies

Li-Ion negative electrode technologies

In the previous WATTALPS TechLetter, we have reviewed the different positive electrode technologies available on the market. We will now study the negative electrode. Li-Metal It is the most obvious negative electrode and the one that is commonly used in laboratories....
Lithium-ion positive electrode technologies

Lithium-ion positive electrode technologies

As explained before, the wording “lithium-ion battery” covers a wide range of technologies. It is possible to have different chemistries for each positive and negative electrode (anode or cathode). Each technology has its interest, as shown in the following figure...
