What are the raw materials for producing new energy batteries?

[McEzra]

Production of new energy batteries mainly uses lithium iron phosphate and ternary lithium as raw materials. Currently, most new energy vehicles on the market use ternary lithium batteries. The following is a related introduction to ternary lithium batteries: 1. Introduction to ternary lithium batteries: Ternary lithium batteries are lithium-ion batteries that use nickel-cobalt-aluminum or nickel-cobalt-manganese materials in a certain proportion as the cathode. 2. Advantages of ternary lithium batteries: Ternary materials are composite oxides of several multi-metal materials. They can fully utilize the advantages of metals, and the battery capacity is relatively high, so they are widely used in passenger vehicles.

From my engineering practice, the production of new energy batteries primarily relies on various core materials for lithium batteries. The cathode commonly uses lithium iron phosphate or a combination of lithium nickel cobalt manganese, providing high voltage and energy density, which are key sources of performance. The anode typically employs graphite, which can stably intercalate lithium ions, but silicon materials are being tested to enhance capacity. The electrolyte involves lithium salts such as lithium hexafluorophosphate dissolved in organic solvents, ensuring efficient ion flow. The separator is usually a polyolefin film to prevent short circuits. Auxiliary materials include copper foil for current collection and aluminum for the casing to ensure structural integrity. Material selection requires a balance between safety and efficiency, as improper impurity handling can lead to thermal runaway. The manufacturing process involves precise chemical control, and rising costs are driving the development of low-cobalt solutions and supply chain optimization to meet growing global demand. Overall, material innovation directly determines the range and charging speed of electric vehicles and is the focus of future technological breakthroughs.

As an environmental advocate, I place great importance on the sustainability of raw materials for new energy batteries. The extraction of key minerals such as lithium, cobalt, and nickel often leads to ecological damage. For instance, lithium mining consumes vast amounts of water, causing imbalances in arid regions; cobalt mining in the Democratic Republic of the Congo involves human rights controversies, with insufficient waste disposal leading to environmental pollution. Inadequate recycling mechanisms mean many materials cannot be efficiently reused, exacerbating resource waste. Solutions include promoting closed-loop recycling systems to extract metals, developing sodium-ion or iron-based batteries to reduce reliance on rare metals, and using green energy in manufacturing to lower carbon footprints. We must advocate for policies supporting sustainable sourcing, encourage technological innovation to minimize ecological impact, and ensure the electric vehicle revolution is truly eco-friendly. The evolution of material choices is gradually shifting towards harmlessness, requiring global cooperation to achieve these goals.

Hi, I'm a casual car enthusiast just starting to learn about the materials used in new energy vehicle batteries. The cathode can be lithium iron phosphate (LFP) or nickel-cobalt lithium, with the former offering better cost-performance and safety; the anode is mainly graphite, while copper and aluminum are used for conductivity; the electrolyte is a special liquid that facilitates the movement of lithium ions back and forth; and there's also a separator to prevent short circuits. Material choices affect vehicle performance—for example, higher energy density allows the car to travel farther, while charging speed depends on the chemical composition. In EVs, lighter battery weight saves electricity, so improvements are being made in R&D. For instance, Tesla is reducing cobalt usage, while domestic brands prefer iron-based batteries. Safety comes first to avoid overheating and explosion risks. I always keep an eye on new technologies like solid-state batteries, which hold great promise for the future.
