The Problem With Fast Charging
One of the major drawbacks of EV over the IC engine vehicle is charging time. As we know filling the gasolene tank only takes a few minutes. however, for the same drive range, it takes about an hour for an EV to recharge itself even with a fast charger. In this blog, I will discuss some of the problems with fast charging in the case of LiB. Before we dive into what happens inside LiB when we try to fast charge, I would like to talk a bit about LiB construction. LiB Construction In my previous blog, ' How Does The LiB Work? ', I indicated LiB as a simple construction with 2 electrodes (Anode and Cathode) placed in an electrolyte. As shown in figure 1. Figure 1. Oversimplified LiB However, the construction of an actual Lithium-ion cell is not at all like what I have shown above! In an actual cell, Anode and Cathode are placed very close to each other in order to pack as much active material (material which takes part in intercalation/de-intercalation) as poss
