Factors influencing the aging of lithium-ion batteries The main factors influencing the aging of lithium-ion batteries are : The number of cycles (charge/discharge) This is the most commonly used factor to chose a battery since it permits to estimate the return on...
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...
A better sustainability for lithium-ion batteries Numerous scientific studies have been published on this topic. For the vast majority, the sustainability of lithium-ion batteries is way better than that of internal combustion engines (diesel and gasoline). Let us...
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...
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...
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....
