We are familiar with the lithium-ion batteries where graphite anode is being used widely, but not familiar with the relatively newer graphene based anode. Recently, researchers of Rensselaer Polytechnic Institute have claimed that they have developed a new graphene based anode that will not only charge batteries 10 times faster than current lithium-ion batteries but also discharge 10 times faster.
The new graphene based anode uses defects in the material. To find out the defects of the graphene, researchers at first took a graphene-oxide paper sheet and have used laser or camera flash. When the researchers saw that the graphene paper was being damaged then they expanded its thickness. That means, the paper has been damaged for its large voids between the graphene sheets. At last, they found the defects and made this new anode material.
According to the researchers, their discovery is ready for commercialization. Even, a patent application has been filed. The researcher team also indicates that they will make a full battery by using a high-power cathode.
