Ever since Tesla's acquisition of Maxwell technologies in high-power systems there's been much speculation about a tesla solid-state battery. However, while all eyes on the far-reaching goals of solid-state batteries, the truth is that Tesla may not even need solid state batteries. With the recent developments of dry, electric batteries in mid-may Tesla will be unveiling their battery developments on Tesla's battery investor day in this video, I'm gon na explain why there's a high chance tesla unveils groundbreaking, dry, electro technology and i'm gon na show you the evidence that Boxes up in 2019, Tesla's acquisition of Maxwell technologies manifested a clear thinking, vision of a battery revolution with dry electro technology. In fact, in Maxwell's presentation back from 2019, they highlighted that their business was split into two key components: energy storage in the dry battery electrode dry battery electrodes were not just a portion of Maxwell's potential, but rather the majority of Maxwell's potential Maxwell's energy storage business was Projected to be worth one point: three: five billion dollars by 2023.

On the other hand, dry battery electrodes were predicted to be worth multi billion dollars, Tesla's intent when purchasing Maxwell technologies must have been because of their promising drive battery electrode technology. After all, it makes up of the majority of Maxwell's potential in 2017. Elon Musk described in a conference, call how, if a company really has a very big three, they should send a sample to Tesla the week where somebody has like some great claim that they've proposed or some batteries, you know what send us a sample or if you Don't trust us incentive to an independent lab where the parameters can be verified, otherwise SPF yeah, so everything works on power point you know it's like. I keep your PowerPoint presentation about teleportation to the Andromeda galaxy.

That doesn't mean it works, so it says it's the biggest buyer of lithium-ion batteries on earth. You know people come to first when they start looking my battery up because we're the biggest customer in 2019 Maxwell technologies cleaned out their drive battery electrodes already demonstrated performance of 300 watt hours per kilogram in our own path to 500 watt hours per kilogram. To put this into perspective Maxwell's, claiming that the current technology of 300 watt hours per kilogram would allow the model 3 to get 450 miles of range on one charge versus the 322 miles it currently has. Eventually, Maxwell is looking to have that range increase.

The 600 miles do it's dry, electro technologies. This claim was made a few months before Tesla's acquisition of the company four months before the acquisition. One of Maxwell's goals was half strategic partnerships within the next six months. What I believed happened here was that Maxwell Center dry electric batteries to Tesla, which, as Elon Musk explained, is the largest customer of lithium-ion batteries, like some great claim awesome battery.

You know what, once this technology was evaluated by musk and Tesla's team, they realized the potential of technology and purchased the company in the conference. Call you all listen to earlier in this video. You all must claim that there were some avenues with potential for a battery breakthrough, but he hesitated to mention what it was. Some breakthroughs that I think are achievable they're confidential.

So I can talk button on this call, but there's one particular venue that I have done coffin could be made to work. That would be no no fellas the most significant one breakthrough in in a while, but but a game that bit in the lab. It doesn't work, it doesn't yet working your leg, promising in the lab you go from the lab to small production. You go to large production, then you get to cost optimization.

You know several years. Ok, I wish it was shorter. That's pretty good, keep in mind that earlier in this call, he talked about how solid-state batteries only working power points, so he can rule that out. This is where the dots start to connect.

Maxwell's claims of the dry electric battery were clearly quite groundbreaking. We talked about how the dry electrode batteries magical technologies had in 2019 would increase the range of the model 3 to 450 miles, but it also came with more benefits, including extending the battery life to up to two times more lowering cost reproduction by 10 to 20 Percent and increasing the production capacity density while using no solvents just four months after Maxwell made. These claims has law acquired the company as Elon Musk said, salty batteries don't work, but there is some other groundbreaking Avenue for batteries. This was stated in Tesla's, q2 2017 conference call in Maxwell officially announced there dry electro technology in their q4 of 2017.

Clearly, Maxo was already developing its dry electrodes before the official release in q4 of 2017, making it quite clear that Elon Musk was talking about Maxwell's dry electro technology. After connecting the dots, it seems like there's a high chance, Tesla will reveal their dry electric battery on Tesla's battery investor day, but many of you are probably wondering what exactly is this dry electrode technology? Less than two weeks after Tesla, apart Maxwell, a few employees revealed the results of the dry electrode coating technology experiments. Normally, a battery consists of the electrolytic solution, a node and cathode. The anode and cathode are the electrodes, with the cathode being the positive side in the anode being the negative side.

These electrodes transfer energy through the transfer of ions. However, the coating of the anode and cathode makes a huge difference on this discharging process. Tesla's current battery uses wet coating technology in which a solvent is used to coat the electrodes. This has many drawbacks, including solvent toxicity, reactivity, with the electrode material and solvent and unwanted changes to the properties of coated electrodes.

All of these issues are fixed through dry electrode technology. In addition, there are many benefits that come with dry electrode technology. Dry coating allows for batteries to work more efficiently at higher temperatures. This is due to the cohesion and adhesion of dry coating, but for the scope of this video we don't need to go over those concepts.

Dry coating also allows for significant savings in manufacturing costs in comparison to wet coating and, last but not least, dry coating decreases. The co2 pollution in the battery electrode manufacturing process by eliminating the use of solvents we'll go more into the benefits of dry electrodes in terms of electric vehicle performance in a later segment. The reason why the costs are far lower for dry coating routes deep into the dry coating process. The first step is to obtain the silicon based materials that are used in this coating.

This material is widely available and consists of lithium, nickel, magnesium, copper, oxygen, aluminum iron, phosphorus and sulfur. I'm sure we can all agree that those are pretty common elements, then the next step would be to mix the powder which can be easily automated with machines. After that, the next step is to go from powder to film formation, as that powder needs to be transferred to material that can actually coat. The electrode then laminate the film another process that can easily be automated and last but not least, dry.

The laminated film. In a vacuum at 120 degrees Celsius, in order to remove moisture, this five-step process is quick, easy and cheap, allowing for an increase of 16 times in the production capacity density. The results of Maxwell studies with distract coating were quite promising. The batteries now had impressive.

Discharging rates which resulted in far higher capacity retention compared to wet coated electrodes with higher capacity retention. This would increase the driving range by a substantial amount. The next groundbreaking result was an increase in power capability. The high level power capability of the dry electrode would allow for far higher performance of Casals vehicles than what they already are along with significantly better performance.

A higher power density would also mean that charging rates would be considerably faster than before. The last benefit of the experiment was higher power retention. The battery was able to maintain 90 % of its original capacity after 2,000 miles with Maxwell's previous claim of a 450 mile range battery. This would mean that the body would be able to go 900 thousand miles before degrading 10 %.

Remember Elon Musk's promised to deliver a million mile battery when musk made this claim. He must have been thinking of the dry electrode battery breakthrough. A breakthrough doubt easily allow Tesla's to last 1 million Mouse. High bar systems is a company known for its state-of-the-art equipment.

This must have been a strategic acquisition by musk in order to help reduce the equipment needed in order to ramp up dry electric batteries.
