According to a report by the Physicist Organization Network on September 3, researchers at South Korea's LG Chemical Co., Ltd. said that they have developed a flexible lithium-ion battery that looks like a wire. The battery has excellent flexibility, can withstand greater bending and deformation, and can still work even after knotting. This achievement is expected to break through the design bottlenecks of existing mobile electronic products, paving the way for the emergence of flexible folding mobile phones and computers. Related papers were published in the latest issue of Advanced Materials magazine.
The traditional lithium-ion battery has a large volume, occupies a large proportion in the overall volume and weight, and has always been a major obstacle to the design and development of mobile electronic devices. As early as a few years ago, some experts predicted that flexible electronic products that could be bent or worn would become the mainstream of the next generation of electronic products. Before this, we must first develop a flexible flexible battery.
Although there have been many flexible batteries available before, these batteries are mostly flat and have limited capacity. In contrast, the cable-shaped flexible lithium-ion battery developed by LG Chemical Co., Ltd. is more flexible and can be better integrated into the design of the product.
The researchers said that this prototype battery has excellent flexibility, and can also withstand a certain degree of stretching. They used a cable-shaped lithium-ion battery with a length of 25 cm in the experiment to drive a small MP3 and a red LED display, respectively.
The researchers said that the popularity of such batteries will likely make the appearance of existing mobile devices have changed dramatically. In the field of portable electronic devices, the most important limiting factor is the shape of the battery. After this difficulty is broken, it will open up a new path for product design and innovation. Currently, they are testing a new type of anode material so that the battery can achieve greater capacity and faster charging speed. In the next step, their goal is to realize the mass production of such batteries as soon as possible.
It is understood that LG Chemical Company has long been dedicated to the research and development of batteries, and began mass production of lithium-ion batteries since 1999. As of 2008, LG Chemicals has become Korea's second-largest and fourth-largest lithium-ion battery manufacturer in the world. (Wang Xiaolong)
7.5L Electric Wallpaper Stripper
The 2200W 7.5L Electric Steam Wallpaper strippers is the most productive, safest and easiest to use steam wallpaper stripper.
The Wallpaper Stripper force steam through the layers of paper, helping to not only remove the paper but also glue residue from walls.The Wallpaper Steam Stripper is particularly effective on stubborn papers with paint on, or wood chip paper.
The 7.5L Electric Wallpaper Remover Stripper is much easier, compared to soak and scrap off the wallpaper manually, it only uses water which is heated.
Once the water boil then the water evaporates, produces steam out of the plate. The steam will penetrates into the wallpaper and loosen the old adhesive paste, so the wallpaper can then be pulled off and removed easily.
The advantages of removing wallpaper with steam are obvious: no need for chemicals, which is cheap and good for the environment. It's also much faster--you do not need to soak. BTW, no large puddles of water on the floor. What`s more, it makes work easier because large pieces can be removed from the wall.
