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...
Wattalps has been awarded 180,000€ for the national startup contest i-LAB, for innotative technology. On Thursday, September the 6th, Matthieu DESBOIS-RENAUDIN, President of Wattalps, has been invited in Lyon for the awards. Wattalps project has been selected in the...
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....
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...
