Carbon nanotubes can revolutionize lithium-ion batteries

　　From mobile phones to electric vehicles, lithium-ion batteries have now become the main energy storage device. Now, research shows how to make them more environmentally friendly and gain more power. By using carbon nanotubes, a team of Indian scientists from Clemson University in the United States eliminated the need for toxic organic solvents in traditional batteries.

By using carbon nanotubes, a team of Indian scientists from Clemson University in the United States eliminated the need for toxic organic solvents in traditional batteries.

　　The research team then used a lithium active material called lithium iron phosphate or LFP mixed with a binder in water to make battery electrodes on carbon nanotube-coated aluminum foil. The adhesive helps the active substance to adhere firmly to the underlying foil.

　　The energy and power of the battery

　　``During the charging process, the lithium ion battery transfers lithium ions from the lithium active material on one side and traps them in the graphite electrode on the other side. During the discharge process, lithium ions leave the graphite and return to lithium-ion active materials to power devices, such as mobile phones or laptops. The performance of a battery is evaluated based on two things: energy and energy.
