Stories about batteries
What are you making?
Reduce the surface area of materials with ultra-fine milling solutions
The battery chemistry determines the performance of the lithium-ion exchange. But the treatment of the materials significantly impacts the energy storage parameters of the final battery cells.
Battery manufacturing technology includes specialized mills to reduce the particle size of materials and increase their surface area. Grinding your chemicals into ultra-fine powders expands a battery pack’s overall capacity and recharge speed.
Distribute particles evenly with specially-designed battery making equipment
Lithium-ion batteries involve more than lithium, and the cornerstone of the manufacturing process is distributing materials homogeneously.
Milling equipment for ion battery production facilitates uniform dispersal by downsizing the minerals into ultra-fine powders. But particle size is only one-half of the effort. The materials must be mixed thoroughly but gently to achieve a consistent base for the electrodes.
Combat lithium dendrite with solid-state battery types
The early wave of electrolytes for lithium-ion batteries were liquid solutions enriched with dissolved salts, acids, or alkalis. But elevating temperatures, particularly while charging the battery, generates internal pressure and produces dendrites.
Solid-state batteries reduce this problem by replacing the liquid electrolyte with a ceramic plate that acts as a physical barrier. Repeated charging cycles still cause dendrite growth, but the solid-state technique offers further advantages. Batteries are lighter, charge faster, and are simpler to recycle.
Round the graphite off to manufacture high-performance anodes
Graphite is the material of choice for most battery anodes as it is sourced relatively easily. But its effectiveness and storage capacity can be enhanced by rounding the particles.
Dedicated battery making equipment, such as classifier mills, apply mild pressure to achieve precise spheroidization. Natural graphite is usually highly irregular in shape, but the synthetic alternative still needs to be rounded.
Finish cathode production with a protective layer
The electrolyte transports the ions between the electrodes but also causes surface erosion of the materials. One strategy to minimize the wear is to coat the cathode and anode with a passivation layer.
Manufacturers apply various coating materials such as carbon black, zirconium dioxide, or magnesium oxide. Use high-shear mixing technology to coat the electrode material entirely and homogeneously.
