CATL M3P // Is the Hype Legit & Will Tesla Use it?
CATL M3P has generated a lot of hype, noise, and confusion over the past year. Is the hype legit and will Tesla soon be using it for the Model 3?
Today I'll try to create some clarity around M3P in terms of energy density, cycle life, and cost... as well what vehicles it could be used in and when that might happen.

*Timeline* 00:00 Introduction 01:18 M3P // What is it? 05:44 M3P // Cycle Life 08:26 M3P // Cost 12:32 Specs // Quick Recap 13:29 Extra Cells Aren’t Free! 14:17 The Hidden Benefit of Voltage 15:12 Lithium Usage and Price Spikes 15:58 Can M3P Replace Nickel? 17:51 When Could Tesla Start Using M3P? 18:55 Summary
What are the advantages and disadvantages of CALT LFP type batteries versus Tesla NCA type batteries what’s the basic science behind them? Today I’ll compare a standard LFP Chemistry like CATL’s to the NCA chemistry produced by Panasonic at Giga Nevada for Tesla to provide a Full Rundown of the Science and Specs.
For those looking for information on the BYD blade battery and Tesla’s 4680 with LFP, those will each be covered in separate videos. This video mainly focuses on chemistry, whereas the Blade and 4680 are mainly form factor changes that come with a host of additional benefits.

The results are in! UC San Diego tested the energy density of the Munro 4680 and today I share the results. I also discuss why the energy density is lower than expected and explain how it appears the Model Y Pack size is fully explained.

If lithium forecasts are conservative and don't account for potential new supply, where are the opportunities for growing the lithium supply by country throughout the rest of the decade?

David Howey runs the Battery Intelligence Lab at the University of Oxford. In this interview we do a deep dive into battery charging curves, from determining the state of charge, to what the core problem is with charging, to trade-off decisions, and does lfp really like to be charged to 100%?

This video is a technical deep dive and walkthrough of Tesla's Tabless Electrode Patent. There is a lot about this Patent that isn't being dicussed, such as the trail of patents by Kunio Tsuruta, reduced heat generation, improved cooling, easier and cheaper manufacturing, and improved cold-weather performance.
The video begins by talking about the three inventors and Kunio's patent history, then talks about the negatives of a tabbed electrode and the positives of a tabless electrode, explains in depth the benefits of the tabless electrode, and then talks in depth about Durr systems and double sided electrode coatings.
