Particle size as a central influence
Overall, the milling of cathode materials, with solutions from WAB-GROUP, helps improve the energy and power density, efficiency and lifetime of batteries, which is critical in a variety of applications, including electric vehicles and renewable energy. Lithium Nickel Manganese Cobalt Oxide (NMC) and others.
In batteries, especially lithium-ion batteries, the cathode can be made of various materials, including lithium iron phosphate (LiFePO4), lithium cobalt oxide (LiCoO2), lithium nickel manganese cobalt oxide (NMC), and others.
Improvement of reaction kinetics
Grinding significantly increases the surface area of the cathode materials. A grösere surface area enables faster diffusion and reaction of lithium ions, which increases the charge and discharge efficiency of the battery. This leads to better performance and faster reaction kinetics.
Increase in energy density
Grinding allows the cathode materials to be produced in a finer form. This enables a higher packing density in the battery, which in turn increases the energy density. A higher energy density means that the battery can store more energy in a smaller space.
Grinding ensures that the cathode materials are mixed more homogeneously. This is decisive for the uniformsdistribution of lithium ions during the charging and discharging process. A uniformssible distribution contributes to the avoidance of unequalsssible capacity decrease and prolong battery life.
Reduction of agglomerates
Agglomerates are collections of particles that can occur in the cathode. Grinding helps to break up these agglomerates and to evenlyssevenly distributed. This leads to improved reaction kinetics and prevents hotspots in the battery that could lead to undesirable reactions.
Optimization for specific applications
Depending on the requirements of a particular battery application, milling can be used to tailor cathode materials to desired properties. This could include increasing energy density, improving lifetime, or adapting to different operating conditions.
