Learn MoreBattery manufacturing At the manufacturing stage, facility workers face exposure to harmful chemicals like solvents, acids, and heavy metals. Long-term exposure to these substances can result in respiratory issues, skin conditions, and other health problems.
The manufacturing process for lithium-ion battery cells involves three critical steps, each with specific hazards and risks. 1. Electrode Manufacturing During electrode manufacturing, raw materials are mixed and coated onto sheets of foil, which then become the cathode and anode electrodes. Hazards involved in these process steps include:
After production of the battery cells, they are usually pre-aged, where the charging rate is gradually increased to form a SEI to protect the anode. Meanwhile, quality checks of battery voltage, capacity and impedance are carried out to remove short-circuited and abnormal cells.
Although manufacturing incorporates several safety stages throughout the aging and charging protocol, lithium-ion battery cells are susceptible to fire hazards. These safety challenges vary depending on the specific manufacturing environment, but common examples include:
However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation. In extreme cases, these defects may result in severe safety incidents, such as thermal runaway.
In some extreme cases, batteries may catch fire spontaneously when not in use, often due to defects in their manufacturing process. For example, an electric vehicle got self-ignited without traffic accident in 2018, Hubei, China . These defects can accelerate performance deterioration, shorten battery lifespan and compromise battery safety.
