These new battery chemistries and designs avoid overheating, are resistant to catastrophic failure, and in some circumstances can be added to a vehicle’s frame to increase strength.
About 10 kilos of the rare earth lanthanum were used in these batteries in the initial generation of hybrid cars. Today, however, the family of lithium-ion (Li-ion) batteries with significantly superior performance has supplanted this battery technology.
Rare earths are naturally occurring minerals that have distinct magnetic properties and are employed in wind turbines and electric vehicle (EV) motors. Alternative technologies must be created to replace rare-earth-based magnets in motors and generators because these materials are costly and in short supply.
Since ancient times, batteries have been produced without the need of rare earth metals. Robert Sansone has created a prototype electric vehicle battery that uses a synchronous reluctance motor to operate.
Applications for REEs in industry range from electronics to clean energy to aerospace to automotive to defence. The production of permanent magnets, which accounts for 29% of the anticipated demand, is the single biggest and most significant end application for REEs.
The fact that rare earth ores frequently include radioactive thorium and uranium, which have particularly bad impacts on health, is the most concerning. Overall, 2,000 tonnes of toxic waste are produced for every tonne of rare earth.
The Global Rare-Earth Free EV Battery market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Rosen Solar Energy Co., Ltd. A novel electric motor without rare earth metals is being developed by Renault, Valeo, and Valeo Siemens eAutomotive. To achieve the lofty objective of creating an electric powertrain system that is “unparalleled worldwide, offers more power on less energy, without the use of rare earths,” the three firms will pool their expertise.
The overall motor architecture as well as the rotor technology for Electrically Excited Synchronous Motors (EESM) will be developed and produced by Renault.
The stator, which is the stationary component of the system that generates a magnetic field, will be developed and manufactured by Valeo and Valeo Siemens eAutomotive. According to Valeo, it will generate greater power without using more electricity.
We are thrilled to be working with Valeo, whose expertise is respected all around the world. Together, we will create a brand-new line of cutting-edge electric motors that will be manufactured at our Cléon plant. This collaboration is another another example of our ability to lead the electric revolution in the automotive sector and to establish France at the centre of the new automotive value chain.
High-performance electric vehicles are the sole target market for CATL’s “HP” series of rare-earth-free EV batteries. These batteries are perfect for use in sports cars, high-speed trains, and other high-performance electric vehicles because of their high power output and quick charging capabilities. The sophisticated NCM 712 technology from CATL, which is used in the HP series batteries, refers to the cathode chemical ratio of 7:1:2 (nickel, cobalt, and manganese).
High-performance electric cars are a good fit for this technology because it strikes a compromise between high energy density and high power output. Excellent thermal stability is another feature of the NCM 712 technology that contributes to the battery’s longer lifespan and enhanced safety capabilities. The high power output of the HP series batteries is one of their primary characteristics.
These batteries have a discharge rate of up to 10 C, so they can offer a quick burst of power for acceleration or high-performance driving. As the battery can tolerate a larger charging current without overheating, the increased power output also enables quicker charging periods. The HP series batteries’ ability to charge quickly is another crucial quality.
Using a rapid charging station, these batteries may be charged to 80% of their capacity in just 15 minutes. Due to their quick charging durations, they are perfect for usage in electric vehicles like high-speed trains and delivery trucks that are used for business purposes. For high-performance electric cars that need a mix of high power output and quick charging ability, CATL’s HP series batteries are a great option.
They are perfect for a variety of high-performance applications because of their cutting-edge NCM 712 technology, which balances energy density and power output. The HP series batteries are certain to be a popular option among producers of high-performance electric vehicles because of their great thermal stability and quick charging capability.
In order to lessen reliance on rare earth elements, which are expensive and ecologically harmful to extract, BMW and Northvolt have partnered to produce rare earth-free batteries for electric vehicles. Because they are more widely available and less expensive than rare earth minerals, businesses want to employ a mix of nickel, manganese, and cobalt in their batteries.
The alliance will also concentrate on establishing a raw material supply chain for battery manufacturing that is sustainable. This involves guaranteeing fair labor conditions, minimizing the negative effects of mining and processing on the environment, and obtaining raw materials ethically. The businesses will also focus on creating recycling methods to extract useful components from old batteries.
To create rare-earth free batteries for its electric vehicles, Volkswagen has invested in QuantumScape, a firm that makes solid-state batteries. Batteries made by Quantum Scape don’t require a liquid electrolyte that comprises rare earth elements since they employ a solid-state electrolyte instead. The collaboration intends to produce batteries with increased energy density and quicker charging periods.
Volkswagen intends to begin implementing solid-state batteries in its cars by the end of the decade because they have the potential to greatly enhance the performance and safety of electric vehicles.
