Optimizing Performance and Longevity: Discover how detecting leaks early helps maintain the structural integrity of battery cells, enhancing performance and extending their lifespan.
Reliable leak testing of battery cells is crucial because the highly flammable electrolytes they contain can spark fires. Even small amounts of humidity in a battery module can cause the system to short circuit, reduce service life and degrade performance, including a vehicle's driving range.
A method is presented discussing how to reliably and quantitatively detect leakage from battery cells through the detection of escaping liquid electrolyte vapors, typically dimethyl carbonate (DMC). The proposed method does not require the introduction of an additional test gas into battery cells.
Leak testing plays a critical role in the assembly of battery cells, modules and packs. Batteries need to be leak-free and protected from humidity, water and other liquids for 10 years or more. Reliable leak testing of battery cells is crucial because the highly flammable electrolytes they contain can spark fires.
Rapid detection of leaks in the production of battery cells is absolutely essential to achieving necessary service life and safety requirements. This applies particularly to small leaks that cannot be detected immediately after the cell has been manufactured, for example by using an electrical discharge method.
For instance, the cooling circuit is leak tested with air, while the battery cells are tested with either tracer gas or ionized air methods. “An in-process leak test is to check every battery subassembly, such as cells, cooling plates, cooling circuits, venting valves, trays and covers,” Dewailly points out.
For pouch cells, no reliable method to detect small leak channels is available. This paper examines the spectrum of possible leak scenarios for cylindrical, prismatic and pouch lithium-ion batteries [ Figure 1 ]. Currently no rejection limits have been codified for these batteries.

EXCEPTION: Battery lugs with a solder contact length of not less than 1. 5 times the diameter of the conductor. NOTE: When a stranded conductor is soldered, the soldered portion of the conductor becomes a solid strand conductor, and flexing can cause the conductor to break at the end of the solder joint unless adequate additional support is.
The most common soldering defect on PCB boards is solder bridging, which occurs when solder accidentally connects two or more pins or pads that should not be connected. Can all soldering defects be detected visually?
Understanding what causes soldering defects is key to preventing them. Here are some of the most common root causes of the failure modes outlined above: Insufficient heat or cooling too quickly during soldering leads to cold joints, voids, poor wetting, and other defects. Excessive solder quantity can create bridges, icicles, and tombstoning.
Uneven heat distribution due to, for example, a damaged tip can require using more solder than needed and tends to create these joints. Applying excessive pressure can also create these undesired “balls” when soldering. When soldering, less solder is better. Only apply the necessary solder to create a solid and secure joint.
Many soldering defects can be repaired through rework, salvaging the PCB assembly. Here are some guidelines for repairing typical defects: Solder bridges: Use a soldering iron, solder braid, or sucker to remove excess solder creating the bridge. Prevent overheating nearby joints.
Insufficient penetration: When the solder does not flow through the entire joint, resulting in a weak or incomplete connection. Barrel fill: The amount of solder present inside a through-hole component's barrel, which is crucial for ensuring a reliable connection.
When working with SMD components, insufficient solder can cause a phenomenon called “Solder Starvation”, resulting in a weak bond that affects the circuit's performance. Weak joints that are prone to cracking when subjected to physical stress. Board failure and malfunction.
