Ready for Battery Technology News? Both Lyten and MAHLE have announced breakthroughs in new battery technology, but neither is an empty experiment from a laboratory 10 years away from production. Both promise low cost, fast charging, and reduced flammability. Let’s take a closer look.
Liten Lithium Sulfur Battery
California-based Lyten Lithium sulfur Pentagon battery cell for several years.so Press releaseThe company is ready to move from defense applications to powering electric vehicles. What’s so special about Lyten technology? Energy density up to 900Wh per kg — about three times that of traditional lithium-ion batteries.
The secret is a special 3D graphene that took years to refine. The company states that this unique material can be designed and tuned at the molecular level to meet the requirements of specific battery applications. By blocking the “polysulfide shuttle,” which has traditionally hindered the use of lithium-sulfur batteries in electric vehicles and is a compromise that shortens battery life, it is possible to unleash the potential of sulfur performance. During Pentagon testing, the LytCell ™ prototype design withstood more than 1,400 charge / discharge cycles.
“We have begun a generational shift from internal combustion engines to BEVs. Lyten’s groundbreaking battery platform is the mass consumption of electric vehicle ownership due to improved performance, range and safety of LytCell EV ™ batteries. We are confident that we will accelerate recruitment by people, “said Dan Cook, CEO and co-founder of Lyten. “We also believe that by providing the most environmentally friendly batteries in the USMCA-compliant supply chain, Lyten will give automakers more confidence in implementing the announced electrification roadmap.”
According to the company, lithium-sulfur batteries are safer than traditional lithium-ion batteries because they do not contain oxygen from metal oxides.That oxygen is in many EVs, especially Chevrolet Volt..
In addition, the company’s batteries make electric vehicles cheaper than traditional vehicles with internal combustion engines, the company said. They can operate at temperatures from -30 degrees Celsius to 60 degrees Celsius. Flexible and scalable pack sizing allows Lyten batteries to meet the needs of a wide range of automotive platforms.
Batteries can be produced in cylindrical, pouch, and prismatic forms at production facilities near automobile factories. The company says its batteries emit the least carbon dioxide of any EV battery, can be charged in less than 20 minutes, and do not contain competing substances such as cobalt. We expect full production and market availability of 2025 and 2026 model vehicles.
Mare Lithium-Carbon Battery
We tend to focus on cars here Casa Clean TechnicaHowever, in many parts of the world, scooters and mopeds are the vehicles of choice, especially in crowded urban environments.Germany’s Mare Is a Tier 1 supplier to the automotive industry. In partnership with Allotrope Energy, we have created a battery for small vehicles that combines the functions of a conventional lithium-ion battery with the functions of a conventional lithium-ion battery. Supercapacitor..
Allotrope’s lithium carbon batteries are fully recyclable, use no rare earth metals, are less susceptible to thermal runaway, and can be recharged in just 90 seconds. “The main barrier to the adoption of electric vehicles is often said to be anxiety about distance, but if we can refuel a conventional IC engine vehicle and charge the battery at the same time, many of those concerns will disappear.” Mike Bassett of MAHLE Powertrain said. Principal investigator.
“With the rise of the on-demand economy, the use of gasoline-powered mopeds for delivery to cities, such as takeaway meals, is rapidly increasing, which contributes to the air quality problem in our cities. Decarbonization of these deliveries has so far unless they maintain an inventory of expensive replaceable batteries or switch to larger, heavier electric vehicles with increased energy consumption. It has proven to be difficult, “says Bassett. (Replaceable battery Easy replacement I’m from Piaggio, KTM, Honda and Yamaha. )
Allotrope Energy’s lithium carbon technology combines the advantages of supercapacitors with traditional lithium-ion batteries to provide cells that can be recharged quickly and maintain excellent energy density. This technology features a fast battery anode and a large electric double layer capacitor cathode separated by an organic electrolyte.
The result is a battery cell that is not affected by the thermal degradation experienced by conventional lithium batteries. Its stability allows for high current supply and fast charging, even at high temperatures, without the need for complex external cooling or complex battery management systems.
The best part is that the battery is cheap and the condenser style cathode is suitable for 100,000 cycles or more. Rare earth metal elimination and complete recyclability of the design make it environmentally friendly both during and after production.
As part of the project, MAHLE Powertrain investigated the use of lithium carbon batteries to power electric mopeds for delivering high-speed food within a 25km target range. Lithium carbon batteries can be charged at 20kW in just 90 seconds. This means you can fully charge it within the time it takes for your next order to arrive.
“Ultra-fast charging allows us to optimize the size of the battery for the scenario in which the vehicle is used. This not only reduces weight, but also reduces costs and lowers the decarbonization barrier.” Says Bassett. “The real challenge was to design an electrical architecture that could absorb such high charges.”
It’s all working, but chargers that can deliver 20 kW of power are uncommon. “Therefore, we created our own custom design,” he adds. The solution devised by his team uses a unique built-in capacitor-based energy storage module to achieve ultra-fast charging by boosting power from a typical 7kW single-phase connection. This reduces cost and complexity while eliminating the need for expensive grid connection upgrades.
Triples the power density. One-third of the charging time. As the EV revolution accelerates, some amazing things are happening. Today, no one remembers a car that had to be started with a hand crank. Eventually, no one will remember when the car was equipped with a hellish combustion engine. The day is getting closer.
