Quality Requirements of Lithium Ion Battery Separators

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Further Improvements on Performance of Weighing Method Water Vapor Transmission Rate Tester

Abstract: weighing method is the basic testing method for water vapor transmission rate measurement. After realizing automatic testing of water method, Labthink has made a series of innovative improvements on weighing method water vapor transmission rate tester with higher testing efficiency and better capability for extension. Thus, customized demands for desiccant method testing and inverted water method testing, as well as testing demands for special samples can be met. Keywords: water vapor transmission rate , WVTR , weighing method , testing efficiency , inverted water method Weighing method has long been the basic testing method for water vapor transmission rate testing with the widest applications, which can be subcategorized into desiccant method and water method, etc. The method needs manual operation in its early stage to accomplish the testing; yet, the relevant instruments are low in automation. Since high efficiency and multi-function are the trend for instrumental devel...
