Battery test

In routine storage and practical applications, lithium-ion batteries often face a variety of environmental and external challenges. Room-temperature storage, high-temperature storage, and shell stress testing are the key verification procedures to address these challenges. The room-temperature storage test focuses on the battery’s ability to maintain performance under normal storage conditions and concerns the reliability of…

In the R&D, mass production, and pre-delivery stages of lithium-ion batteries, environmental performance testing is a critical link connecting laboratory validation with real-world use and transportation scenarios. Through conditions such as high-altitude (low-pressure) simulation, high-temperature and high-humidity storage, and temperature cycling, cells and batteries are systematically evaluated for sealing integrity, capacity retention, and safety thresholds…

Mechanical performance testing is used to simulate the effects of external forces on lithium-ion cells/batteries during handling and transportation, including drops and impacts in transit. It is also used to verify the battery’s overall structural strength, the resistance of tabs and separator to mechanical damage from external forces, and the trigger boundaries for thermal runaway….

With their high energy density, long cycle life, and low self-discharge rate, lithium-ion batteries have become the power source of choice for mobile electronics, electric vehicles, power tools, and energy storage systems. However, when exposed to mechanical abuse, electrical anomalies, or changes in the thermal environment, defects in structural design, protection strategies, or manufacturing processes…

In the R&D, production, and outgoing quality inspection of lithium-ion batteries, electrical performance testing is one of the most fundamental components of quality evaluation. It is directly related to capacity delivery, cycle life, charge–discharge efficiency, and stability under different temperature conditions. This article comprehensively summarizes the electrical performance test items for polymer lithium-ion cells and…
