Nanomaterials are extremely tiny particles made from atoms, that you would need a very powerful electron microscope to see. Their composition gives them special powers that are not present in larger materials. Battery chemists have begun using nanomaterials for better batteries, and are achieving remarkable results as we share here.
Building Better Batteries Using Nanomaterials
Nanomaterials are so tiny that they measure billionths of a meter across. They comprise even tinier nanoparticles, which we can imagine as building blocks in unique arrangements.
Being so tiny almost seems to free nanoparticles from the limitations of our larger physical world. For example, they can conduct electricity, and react with other substances in interesting ways. They can even interact with light and electricity differently to “normal” materials.
Scientists are finding exciting new ways to use these nanomaterials in medicine, electronics and chemistry. However, our interest lies in using nanomaterials for better batteries, and here too, there are excellent results in the field of lithium-ion chemistry.
Powerful Faster Lithium-Ion Batteries With Nanomaterials
Using nanomaterials for battery electrodes, means the ions do not have to travel so far during charging and discharging, The benefits are already showing in more efficient batteries, able to charge faster and store more energy.
But nanomaterials also help in other ways too, notably in terms of battery safety and durability. Here their ability to tolerate structural changes during discharging and recharging, prevents damage developing over time.
Bur perhaps nanomaterials’ greatest advantage is their ability to increase their surface area compared to battery volume. This benefit improves the interface between the electrodes and the electrolyte. And this in turn enables more rapid ion movement, and with it faster battery cycling.
Nanomaterials allow battery engineers to fine-tune lithium-ion batteries for optimum performance. These changes are gradually making the transition to renewable energy a reality, one that future generations may need in order to survive and prosper.
