EU Develops New Customized Garment Industry Technology

< p > recently, the total R & D investment has reached 5 million 200 thousand euros. From the "a href=" http://www.91se91.com/news/index_c.asp "EU" /a "9 Member States and the associated countries Germany, Holland, Tunisia, Italy, Belgium, Ireland, Switzerland, Poland and Spain, the European OPEN GARMENTS R & D team, which is made up of the garment industry and the scientific and technological circles and the innovative small and medium enterprises (SMEs), has worked hard for more than 4 years, and has successfully developed a set of garment industry technology series combining" scale customization and personal customization "using the Internet and cloud computing, which will open a revolution in the European garment industry.

< p > new carbon nanotube (CNT) composite yarns, which are newly researched and designed, can be tightly wound into cotton fibers to create high-performance lithium-ion batteries.

The diameter of the fiber is about 1 millimeters, it can be woven into flexible fabric or cloth, and is compatible with flexible wearable electronic equipment.

Weng Wei, who took part in the research, said: "it is very necessary that this power supply can be directly integrated seamlessly into wearable electronic products." P

Because it needs to be woven into clothing flexibly, the fibrous power supply is ideal.

Although this is the first carbon nanotube like lithium ion battery, it exhibits excellent electrochemical performance, including high energy density up to 750 billion watts / square centimeter, and after 100 cycles, the battery has a capacity of 87%.

One of the biggest challenges in designing P based lithium ion batteries is the widely known problem of silicon expansion.

Chemical reactions will occur during charging / discharging processes, and the volume of silicon will undergo a great change of 300%.

To adapt to this situation, the researchers introduced carbon nanotube into a composite CNT/ silicon yarn anode.

Carbon nanotubes effectively buffer the volume change of silicon and solidify it.

Without such a hybrid structure, the expansion of silicon will cause it to peel off and lead to battery damage.

< p > for the cathode materials, researchers use carbon nanotubes and lithium manganate. The advantages are high stability, high working voltage and low cost.

By making the CNT based yarn separated from the anode and cathode separated by gel electrolyte into cotton fibers, the lithium-ion battery can be woven into a flexible fabric.
