Battery quality is among the most difficult issues facing the industry today due to the complexity of both battery failure and gigawatt-hour-scale battery production. Yet the human, environmental, financial, and reputational stakes are enormous. The challenge of battery quality deserves much more academic, industrial, and regulatory focus.
4.1. Method for quality man agement in battery production quality management during production. This procedure can be format and process structure. Hence, by detecting deviations in control and feedback are facilitated. properties. Among the external requirements are quality performance or lifetime of th e battery cells . Internal
While battery quality control is a multifaceted problem worthy of its own article, a key element is inspection. Battery inspection techniques can identify process failures before defective cells leave the factory and provide a snapshot into manufacturing performance.
Under this definition, poor quality means that the as-built cells deviate substantially from their design. This definition of battery quality is more general since it can include dimensional specifications and electrochemical properties as well as the lack of physical defects. Poor conformance has a number of impacts on the final product.
Quality management for complex process chains Due to the complexity of the production chain for lithium- ion battery production, classical tools of quality management in production, such as statistical process control (SPC), process capability indices and design of experiments (DoE) soon reach their limits of applicability .
Table I. Key features of cell-level battery quality inspection techniques. Spatial resolution on the order of 10–100 μm is important for detecting many critical battery defects, such as anode-cathode overhang and metallic particle contaminants (see Figure 3).
