Manganese-rich cathode active materials such as LiMn2O4 have long been considered an interesting option for their low cost, high voltage, and relatively low environmental impact, but they haven’t been seriously considered for electric vehicles due to a tendency for rapid degradation. Now, Tesla has patented new ‘doped manganese-rich cathode active materials’ that it claims increase the longevity of those battery cells. In the patent application, Tesla writes that its “doping” of the materials results in better capacity retention at 50 cycles than regular manganese-rich cathodes:

Tesla reveals plans for new 4680 LFP battery cells, aiming to reduce dependence on Chinese batteries. The company is also preparing updates for its Supercharger Diner experience and software features, including FSD improvements and insurance discounts. 𝗦𝗼𝗼𝗺𝗮 𝗔𝗿𝘁𝗶𝗰𝗹𝗲 Tesla is making significant strides in battery technology with the development of a new 4680 battery cell using lithium iron phosphate (LFP) chemistry. This move is set to revolutionize the EV industry and reduce America's reliance on Chinese battery production. The information comes from a Tesla patent filing released on January 16th under the World Intellectual Property Organization, detailing the manufacturing process for LFP cathode material. LFP batteries replace expensive and hard-to-source nickel, cobalt, and aluminum with abundant iron. While they may not be suitable for high-performance, long-range vehicles, they work well for economy-focused cars. The expiration of Chinese patents on LFP technology has opened up the market, allowing Tesla to develop its own production methods. Enjoying this article?

What advances can we expect in electric car batteries? Batteries play a fundamental role in electric vehicles by determining their ability to store and supply energy. Therefore, one of the main focuses of research and innovation is directed towards improving their performance, durability, safety, and cost. A significant advancement in this field is the development of the 4680 battery cells introduced by Tesla in their Model Y. These cells have larger diameter and height compared to conventional ones (46 mm vs. 21 mm diameter and 80 mm vs. 70 mm height), which increases their energy density, power, and range. According to Tesla, this results in a 16% increase in range and a 14% reduction in cost per kWh. Another important advance is the use of alternative materials in the chemical composition of batteries, such as lithium iron phosphate (LFP) or lithium nickel manganese cobalt oxide (NMC). These materials offer advantages like greater thermal stability, reduced dependence on cobalt (a scarce and expensive metal), and extended lifespan. Some manufacturers, like BYD or Volkswagen, have already adopted these technologies for their electric vehicles. #EMCIL #emobility #sustainablemobility #electricvehicles #batteries #performance #durability #safety #technology #advancements

Interesting how Tesla managed to pull that off, if this is true. The PTFE fibrillation method developed by Maxwell Technologies is intended more for cathode dry coating. If Tesla is still using this very method, it means they have finally figured out how to get around the problems five years after acquiring Maxwell.

Copper content in EVs is expected to decline ~11% between 2024 and 2030; this will help make next generation EVs cheaper and lighter. Takeaways: Thrifting, the process where engineering teams continuously improve the efficiency and performance of various components, is leading to reduced copper usage. Major copper savings will come from reduction in thickness of copper foils for battery packs, localized wiring architectures removing hundreds of meters of redundant copper conduits, and introduction of aluminum busbars to replace copper solutions. Fun fact: Tesla’s CEO, Elon Musk, said that Model S has about 3 km of wiring harnesses, and Tesla brought it down to 1.5 km in length for the Model 3. Tesla’s new wiring architecture for future vehicle platforms aims to bring it down to just 100 meters.

Tesla's collaboration with Chinese battery manufacturer CATL has been pivotal in advancing electric vehicle (EV) technology. CATL supplies Tesla with lithium iron phosphate (LFP) batteries, known for their cost-effectiveness and safety, though they offer less range compared to other chemistries. This partnership has enabled Tesla to produce more affordable EVs, particularly in the Chinese market. However, CATL's founder, Robin Zeng, has expressed skepticism about Tesla's focus on 4680 cylindrical cell technology, predicting potential challenges in its implementation. Despite these differing perspectives, the collaboration between Tesla and CATL continues to play a significant role in the evolution of battery technologies within the EV industry. #Tesla #CATL #EVBattery
