The team at PEI are experts at working with diverse metals and alloys for high-precision battery components.
In lithium-ion batteries, the cathode and anode materials play a crucial role in determining energy density, efficiency, and overall battery performance. The common cathode materials are typically metal oxides, including lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium iron phosphate (LiFePO4 or LFP), and lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC).** Each of these positive electrode materials offers different advantages in terms of thermal stability, energy capacity, and cost-effectiveness.
On the negative electrode side, anode active materials are usually carbon-based, with graphite being the most widely used due to its high electrical conductivity, stability, and affordability. Silicon anodes are gaining popularity for their higher energy density, but they present challenges like volume expansion and shorter cycle life. To optimize performance, manufacturers often dope graphite anodes with small amounts of silicon, balancing stability and efficiency.
The cost of processing raw materials for cathodes accounts for 30-40% of a lithium battery cell’s cost, while anode materials make up about 10-15%. With the rising demand for sustainable battery solutions, the industry is increasingly focused on reusing valuable materials to reduce waste and enhance cost efficiency in battery production.
The anode is the negative electrode, which releases electrons during discharge, while the cathode is the positive electrode, which stores and releases energy. Together, they facilitate the flow of electricity in an electrochemical cell, enabling efficient energy storage and power delivery.
The choice of anode and cathode materials affects energy density, charging speed, cycle life, and overall efficiency. Graphite anodes are widely used for stability, while silicon anodes offer higher energy density but face volume expansion challenges. Common cathode materials like lithium cobalt oxide (LiCoO2), lithium iron phosphate (LFP), and NMC impact battery longevity, cost, and thermal stability, making material selection crucial for specific applications.
