Battery & EV Manufacturing Air Filtration

Different Steps in Battery Production Bring Different Risks

Battery manufacturing looks clean on the surface, but a few key steps in the process create real air quality concerns.

Making the electrode material involves mixing fine powders like lithium, graphite, cobalt, and manganese, and handling these powders can release fine particulate into the air. Coating the electrodes uses a solvent, often NMP, and drying that coating releases solvent vapor that needs to be captured. Cutting, slitting, and assembly steps add more fine particulate as materials are shaped and handled. And in rare cases, cell testing or damage can trigger thermal runaway, which releases gas and smoke that needs to be dealt with quickly.

Points in Your Line Worth a Closer Look

• Fine powder is visible settling near electrode mixing or coating areas

• A solvent smell is noticeable near coating or drying lines

• You're scaling up electrode production or adding a new line

• Cell testing areas don't have dedicated air handling

• Standard HVAC filters are struggling with nano-sized particles

• You've never tested air quality near powder handling stations

Catching Powder Too Fine for Standard Filters

Electrocorp combines high-efficiency particulate filtration with carbon stages to address both halves of the battery manufacturing air problem. The particulate stage is built to catch very fine dust from lithium, graphite, and other electrode materials, since standard filters often let these smaller particles through. The carbon stage adsorbs solvent vapor released during electrode coating and drying. Units can be placed at powder handling, coating lines, or testing areas depending on where your risk is highest.
