How to buy Lithium Ion cells

Lithium-ion batteries have a higher energy density, especially the battery module, in the event of an accident, conventional means can not effectively control the rapid spread of heat or prevent the continuous explosion of the battery, which may have serious consequences. Especially in the case of lithium batteries burning or exploding during air transportation, the consequences to passengers and aircraft would be very serious or even catastrophic. So how exactly did the lithium battery accident happen, let’s look at the characteristics of the lithium battery itself. Lithium battery characteristics 1 High Energy Lithium battery is a high-energy item, if it catches fire and explodes, the danger is enormous. Take the 300Wh/kg square lithium ion battery for example, 1kg square lithium battery contains 1.08 × 10 6J of energy; 1g TNT can release 4184J of energy, the conversion shows that the energy contained in 1kg square lithium battery is equivalent to about 258g TNT, the energy contained

Since its first publication in 2002, the IEC 62133 series of standards has enabled international harmonization of safety testing of small cells and batteries. Since then, the standard has undergone major revisions in 2012 and most recently a major change in 2017. This article will detail these latest changes and their impact on compliance activities. The scope of the first and second editions of the IEC 62133 standard included nickel and lithium-ion battery chemicals. As technology has evolved, secondary lithium options in both lithium-ion and lithium-polymer forms have overtaken nickel batteries in most portable applications. As production of lithium batteries increased, the cost of lithium plummeted and the economics and safety of lithium batteries changed dramatically. In recognition of this fact, the latest version of the IEC 62133 standard is divided into two distinct parts. Part 1 deals with nickel chemistry and Part 2 focuses on lithium. This has led to some confusion as the pre
