1. Handling of Cells 1.1 Consideration of strength of film package 1). Soft Aluminium foil Easily damaged by sharp edge parts such as pins and needles, Ni-tabs, comparing with metal-can-cased Li-ion battery. 2).Sealed edge may be damaged by heat above 100°C, bend or fold sealed edge. 1.2 Prohibition short circuit Never make short circuit cell. It generates very high current which causes heating of the cells and may cause electrolyte leakage, gassing or explosion that are very dangerous. The LIP tabs may be easily short-circuited by putting them on conductive surface. Such outer short circuit may lead to heat generation and damage of the cell. An appropriate circuitry with PCM shall be employed to protect accidental short circuit of the battery pack. 1.3.Mechanical shock LIP cells have less mechanical endurance than metal-can-cased LIB. Falling, hitting, bending, etc. may cause degradation of LIP characteristics. 1.4 Handling of tabs The battery tabs are not so stu...

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences ,  including burns ,  house fires and at least one plane crash. Inspired by the weird behavior of some liquids that solidify on impact ,  researchers have developed a practical and inexpensive way to help prevent these fires. They will present their results today at the 256th National Meeting & Exposition of the American Chemical Society  ( ACS ) . "In a lithium-ion battery ,  a thin piece of plastic separates the two electrodes , " Gabriel Veith ,  Ph.D. ,  says. "If the battery is damaged and the plastic layer fails ,  the electrodes can come into contact and cause the battery's liquid electrolyte to catch fire." To make these batteries safer ,  some researchers instead use a nonflammable ,  solid electrolyte. But these solid-s...

Scientists at Tokyo Institute of Technology have addressed one of the major disadvantages of all-solid-state batteries by developing batteries with a low resistance at their electrode/solid electrolyte interface. The fabricated batteries showed excellent electrochemical properties that greatly surpass those of traditional and ubiquitous Li-ion batteries; thereby, demonstrating the promise of all-solid-state battery technology and its potential to revolutionize portable electronics. Many consumers are familiar with rechargeable lithium ion batteries, which have developed over the last few decades, and are now common in all sorts of electronic devices. Despite their broad use, scientists and engineers believe that traditional  Li-ion battery  technology is already nearing its full potential and new types of batteries are needed. All-solid-state batteries are a new type of Li-ion battery, and have been shown to be potentially safer and more stable energy-storing devic...

Lithium metal batteries hold tremendous promise for next-generation energy storage because the lithium metal negative electrode has 10 times more theoretical specific capacity than the graphite electrode used in commercial Li-ion batteries. It also has the most negative electrode potential among materials for lithium batteries, making it a perfect negative electrode. However, lithium is one of the most difficult materials to manipulate, due to its internal dendrite growth mechanism. This highly complex process is still not fully understood and can cause Li-ion batteries to occasionally short circuit, catch fire, or even explode. While researchers know that the growth of dendrites, which are needle-like lithium whiskers that form internally in battery electrodes, is affected by how ions move in the electrolyte, they do not understand how ion transport and inhomogeneous ionic concentration affect the morphology of lithium deposition. Imaging ion transport in a transparent electro...
