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....
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...
When you switch from diesel engine to a full electric powertrain, it is no more possible to only think in terms of power. You have to also specify the working time during which you want your power to be available: For on-time smaller than 100 ms, chemical capacitors...
