There are abundant reserves of silicon. Si and Li can be combined to form a Li4.4Si, which has a theoretical specific energy of 4200mAh/g. That is almost 10 times more than the lithium ion that is absorbed by the widely used lithium batteries. In the present day, silicon materials are used in lithium-ion cells mainly for two reasons. The anode is formulated by adding nano-silicon. To improve the performance, organosilicon compounds can be added to the electrolyte.
The University Alberta created a brand new generation of lithium batteries based on silicon
Jillian Biriak and her team at the University of Alberta (Canada) discovered recently that the formation of nano-sized silicon particles can help prevent the material from breaking.
Nano-silicon can be defined as crystalline particles of silicon that have a diameter less than five nanometers. It is a very important non-metal, amorphous substance. Nano silicon powder is characterized as having high purity, a small particle size and uniform distribution. It has high surface activity and high surface activity. Nano-silicon can have a variety of uses: It can be mixed under high pressure with a diamond to form composite materials that can be used for cutting tools, or it can be combined with graphite to form composite materials made from silicon and carbon. The negative electrode material in lithium-ion cells increases the battery’s capacity. This material can be combined with organic matter to create organic silicon polymer.
The team studied and tested four sizes of nanoparticles of silicon to determine which size would maximize its advantages while minimizing the disadvantages. They are evenly dispersed in a highly conductive graphene-carbon aerogel with nanopores that compensates for the low conductivity silicon.
After multiple cycles of charge and discharge, they found that particles as small as one part per meter showed the most stability. This eliminates the limitations of using silicon for lithium-ion cells. This discovery could result in batteries that have 10 times more capacity than the current lithium-ion battery. It’s a major step toward the manufacture of a next generation of lithium-ion-based batteries. The results of this research have been published in the journal Materials Chemistry.
The lithium battery industry’s chain of tens billions in silicon anode sales
This research can be applied in many fields, including electric vehicles. The batteries will become lighter, travel longer and charge faster. Next step will be to create a method that is faster and cheaper to produce silicon nanoparticles. This will make it easier for industrial production.
Other than new energy vehicles, the need for lithium-ion battery with higher energy and power density is also present in energy storage and shipbuilding. The positive electrode is now made from high nickel ternary material, while the negative electrode is made from silicon and its Composite material.
