Any misstep can lead to defects forming in electrodes during the coating process. The profit margins for battery manufacturing are narrow, so the defective coatings must be quickly identified and removed from the production line.
In battery slurries, carbon black forms micron-scale clusters, known as agglomerates, whose size and distribution change based on the slurry formulation and the details of the coating process. In turn, the electrical connections between the carbon black and the active material depend on the size and connectivity of agglomerates.
Carbon black, the conductive nanomaterial most used in batteries today, is a soot-like nanoparticle. The highly engineered type found in batteries is produced at scale by the incomplete combustion of hydrocarbons.
Carbon black, a key ingredient in ancient inks, is used today to make the porous electrodes found in many rechargeable batteries. Understanding how to control its microstructure can pave the way to better-performing batteries.
Repair centres offer a solution in the top layers of the hierarchy. By repairing batteries, they are able to extend the lifespan of batteries considerably. They have a team of experienced high-voltage experts, certified to work on lithium-ion batteries. This is how they operate: Prevention of battery waste (hierarchy level 1)
When a lithium-ion battery arrives at the battery repair centre, it usually goes through 3 phases: Test and diagnosis: the battery is tested and checked for damage. The diagnosis will determine the next steps. Repair: A team of high-voltage specialists repairs the battery or replaces certain parts of the pack.
