Giga Factory Electric Vehicle Battery Facilities: Importance of Moisture Control in Clean & Dry rooms The drive in the Electric Vehicle (EV) battery industry is to increase storage capacities, that last longer and are lighter, charge faster and are safer, and if this is not enough, come in different configurations. This will mean new chemistries and structures, higher density and more narrow film separators between cells.
The EV battery market is growing rapidly as the demand for electric vehicles increases. The global market for electric vehicle batteries is expected to reach $225 billion by 2027. This growth is driven by several factors, including the move to climate rebalancing and carbon reduction, the falling cost of electric vehicle batteries, government incentives and subsidies for electric vehicles. To meet this demand, giga scale facilities must place increasing emphasis on integrated contamination control within the manufacturing environment. This is key to a safe facility and successful product: product failures lead to poor reliability and in some cases catastrophic impacts. A well-integrated contamination control strategy is required and must address all the contaminant risks of moisture and particles, as well as the associated static control and safety risk around gases, both in the manufacturing process and thermal runaway.
electrolytes are highly sensitive and reactive to moisture, so when using them as the basis for EV battery production, it is essential to operate in extremely low humidity controlled cleanrooms and dry cleanrooms. There are numerous reasons for this, from ensuring the highest possible quality and production yield, to providing a safe working space for employees. Issues with moisture can reduce production uptime leading to lost product, poor reliability, significant costs and negative impacts on the environment, also affecting the reputation of a brand and shareholder value. Modern and future EV battery facilities are not just one single ballroom. EV battery manufacturing process steps require dedicated areas such as mixing, coating, deposition, stacking, laminating, milling, electrolyte filling, finishing, packaging and formation. Many of these are separate and dedicated manufacturing spaces, with different environmental control set points and different challenges. Future EV battery manufacturing processes around additive manufacturing, including 3D printing using lithographic techniques will still
