Mark Cuban-backed Natrion has unveiled its latest developments in solid-state battery manufacturing with the new LISIC278 separator in a traditional pouch cell. The separator allows for a higher thermal resistance than other EV batteries, decreasing the risk of fires and combustion. Additionally, the cell showed a 40 percent increase in the charge rate compared to a conventional battery with the same capacity.

Natrion’s LISIC278 material utilizes a Lithium Solid Ionic Composite (LISIC) electrolyte that mimics the performance and specs of a standard polyolefin separator, which sits between the anode and cathode. The purpose of the separator is to prevent short circuits by keeping the electrodes apart while also allowing ionic charges to flow through with the necessary passage of currents in a cell. The LISIC cell can utilize significantly less of the electrolyte liquid by delivering high ion transport capability at ambient conditions. This keeps the cells’ thermal resistance above 200° Celsius (392 F) without having any porosity.

The LISIC278 separator’s ability to remain stable at high temperatures nearly eliminates the risk of fire, while it also exhibits a reduced ability for a thermal event altogether.

CEO and Co-Founder Alex Kosyakov said that reducing flammable liquid electrolytes was a main focus because reducing the perception that battery cells will catch on fire is a key to growing mass EV adoption:

“Reducing our reliance on flammable liquids in EV batteries is key to reducing fire risk and ultimately making mass EV adoption more viable. So the fact that this data shows we can produce battery cells that are just as efficient with only a small fraction of that liquid is a huge win.”

Cycling performance of a two-layer pouch cell at C/3 charge and discharge using LISIC278 with an NMC532 cathode and natural graphite anode.

In addition to the LISIC278 cells’ stability, it also showed a 40 percent increase in charge rate, taking just 3 hours to charge as opposed to 5 hours for a conventional cell with the same capacity. Natrion utilized a standard pouch containing NMC532 cathode, LP40 liquid electrolyte, and a natural graphite anode with a state-of-the-art separator for its experiments. This was compared to the Natrion pouch, which was identical but utilized the LISIC279 separator instead of a conventional design.

Comparison of the cycling performance of two one-layer pouch cells: one constructed with LISIC278 and another constructed with a commercially-available polyolefin separator.

The cell with the LISIC279 separator also displayed a high initial coulombic efficiency. Conventional lithium-ion cells “typically” have less energy available than they are charged with when used the first few times. Natrion cells did not display this issue and “exhibited higher initial coulombic efficiencies and resultantly improved capacity retention at higher C-rates,” the company said.

Dr. Jon Tuck, an expert in energy storage for Silent Koala, said using less electrolyte liquid while maintaining a high initial coulombic rate is difficult, especially at the capacity and C-rate threshold given here. “These results are highly promising and show a versatility of use for LISIC that we have yet to see from other solid-state electrolyte materials. It signals the potential of Natrion’s materials to really advance the industry and the technological feats being developed,” Dr. Tuck added.

Natrion is based in Binghamton, New York, and has operations in Champaign, Illinois.

Solid-state batteries utilize a solid material to allow energy to flow from the cathode to the anode, instead of traditional lithium-ion cells, which utilize a liquid electrolyte solution. EV makers have not been able to switch to solid-state technology due to its complex manufacturing processes. Additionally, researchers have not been able to find ideal solutions for the material it would utilize in the batteries, and this continues to be a severe bottleneck of solid-state development.

Tesla confirms date when new Cybertruck trim will go up in price

Tesla has officially revealed that this price will only be available until February 28, as the company has placed a banner atop the Design Configurator on its website reflecting this.

Tesla has confirmed the date when its newest Cybertruck trim level will increase in price, after CEO Elon Musk noted that the All-Wheel-Drive configuration of the all-electric pickup would only be priced at its near-bargain level for ten days.

Last week, Tesla launched the All-Wheel-Drive configuration of the Cybertruck. Priced at $59,990, the Cybertruck featured many excellent features and has seemingly brought some demand to the pickup, which has been underwhelming in terms of sales figures over the past couple of years.

Tesla launches new Cybertruck trim with more features than ever for a low price

When Tesla launched it, many fans and current owners mulled the possibility of ordering it. However,  Musk came out and said just hours after launching the pickup that Tesla would only keep it at the $59,990 price level for ten days.

What it would be priced at subsequently was totally dependent on how much demand Tesla felt for the new trim level, which is labeled as a “Dual Motor All-Wheel-Drive” configuration.

Many fans and owners have criticized Tesla’s decision to unveil a trim this way, and then price it at something, only to change that price a few days later based on how well it sells.

It seems the most ideal increase in price would be somewhere between $5,000 and $10,000, but it truly depends on how many orders Tesla sees for this new trim level. The next step up in configuration is the Premium All-Wheel-Drive, which is priced at $79,990.

The difference between the Dual Motor AWD Cybertruck and the Premium AWD configuration comes down to towing, interior quality, and general features. The base package is only capable of towing up to 7,500 pounds, while the Premium can handle 11,000 pounds. Additionally, the seats in the Premium build are Vegan Leather, while the base trim gets the textile seats.

It also has only 7 speakers compared to the 15 that the Premium trim has. Additionally, the base model does not have an adjustable ride height, although it does have a coil spring with an adaptive damping suspension package.

Tesla set to activate long-awaited Cybertruck feature

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, as the company has officially added the feature to its list of features by trim on its website.

Tesla is set to activate a long-awaited Cybertruck feature, and no matter when you bought your all-electric pickup, it has the hardware capable of achieving what it is designed to do.

Tesla simply has to flip the switch, and it plans to do so in the near future.

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, according to Not a Tesla App, as the company has officially added the feature to its list of features by trim on its website.

The ANC feature suddenly appeared on the spec sheet for the Premium All-Wheel-Drive and Cyberbeast trims, which are the two configurations that have been delivered since November 2023.

However, those trims have both had the ANC disabled, and although they are found in the Model S and Model X, and are active in those vehicles, Tesla is planning to activate them.

In Tesla’s Service Toolbox, it wrote:

ANC software is not enabled on Cybertruck even though the hardware is installed.”

Tesla has utilized an ANC system in the Model S and Model X since 2021. The system uses microphones embedded in the front seat headrests to detect low-frequency road noise entering the cabin. It then generates anti-noise through phase-inverted sound waves to cancel out or reduce that noise, creating quieter zones, particularly around the vehicle’s front occupants.

The Model S and Model X utilize six microphones to achieve this noise cancellation, while the Cybertruck has just four.

As previously mentioned, this will be activated through a software update, as the hardware is already available within Cybertruck and can simply be activated at Tesla’s leisure.

The delays in activating the system are likely due to Tesla Cybertruck’s unique design, which is unlike anything before. In the Model S and Model X, Tesla did not have to do too much, but the Cybertruck has heavier all-terrain tires and potentially issues from the aluminum castings that make up the vehicle’s chassis, which are probably presenting some challenges.

Unfortunately, this feature will not be available on the new Dual Motor All-Wheel-Drive configuration, which was released last week.

Tesla Model S and X customization options begin to thin as their closure nears

Tesla’s Online Design Studio for both vehicles now shows the first color option to be listed as “Sold Out,” as Lunar Silver is officially no longer available for the Model S or Model X. This color is exclusive to these cars and not available on the Model S or Model X.

Tesla Model S and Model X customization options are beginning to thin for the first time as the closure of the two “sentimental” vehicles nears.

We are officially seeing the first options disappear as Tesla begins to work toward ending production of the two cars and the options that are available to those vehicles specifically.

Tesla’s Online Design Studio for both vehicles now shows the first color option to be listed as “Sold Out,” as Lunar Silver is officially no longer available for the Model S or Model X. This color is exclusive to these cars and not available on the Model S or Model X.

Tesla is making way for the Optimus humanoid robot project at the Fremont Factory, where the Model S and Model X are produced. The two cars are low-volume models and do not contribute more than a few percent to Tesla’s yearly delivery figures.

With CEO Elon Musk confirming that the Model S and Model X would officially be phased out at the end of the quarter, some of the options are being thinned out.

This is an expected move considering Tesla’s plans for the two vehicles, as it will make for an easier process of transitioning that portion of the Fremont plant to cater to Optimus manufacturing. Additionally, this is likely one of the least popular colors, and Tesla is choosing to only keep around what it is seeing routine demand for.

During the Q4 Earnings Call in January, Musk confirmed the end of the Model S and Model X:

“It is time to bring the Model S and Model X programs to an end with an honorable discharge. It is time to bring the S/X programs to an end. It’s part of our overall shift to an autonomous future.”

Fremont will now build one million Optimus units per year as production is ramped.
