There’s a great deal of magic in Lithium-ion batteries that we normally take for approved as well as don’t dig deeper into. Why is the normal full fee voltage 4.2 V as well as not the a lot more practical 5 V, why is CC/CV charging needed, as well as what’s up with all the fires? [The limiting Factor] released a video that describes the low-level workings of Lithium-ion batteries in a extremely easily accessible method – particularly going into ion as well as electron ion exchange happening between the anode as well as the cathode, during both the fee as well as the discharge cycle. The video’s excellent illustrative power comes from an impressively sized investment of animation, script-writing as well as narration work – [The limiting Factor] explains the effort as “16 months of animation design”, as well as this is no normal “whiteboard sketch” explainer video.
This is 16 minutes of pay-full-attention discovering material that will have you glued to your screen, as well as the only reason it doesn’t describe every single thing about Lithium-ion batteries is since it’s that substantial of a topic, it would need a video series when performed in a expert style like this. Instead, this is an exceptional introduction to assist you develop a core of solid comprehending when it pertains to Li-ion battery internals, elaborating on whatever that’s appropriate to the level being explored – be it the SEI layer as well as the organic additives, or the nitty-gritty of the ion as well as electron exchange specifics. We can’t assist however hope that a lot more videos such as this one are coming soon (or as soon as they realistically can), broadening our comprehending of all the other levels of a Li-ion battery cell.
Last video from [The limiting Factor] was an 1-hour banger breaking down all the decisions made in a Tesla Battery Day presentation in likewise excellent level of detail, as well as we appreciate them making a general-purpose insight video – lately, it’s ended up being remove we requirement to go a lot more thorough on such topics. This year, we’ve covered a excellent comparison between supercapacitors as well as batteries as well as appropriate applications for every one of those, in addition to explained the automakers’ reluctance to make their own battery cells. In 2020, we did a breakdown of alternating battery chemistries that goal to replace Li-ion in a few of its crucial applications, so if this topic catches your attention, inspect those articles out, too!
