“What we have so far been able to achieve is a 30% improvement in the amount of charge the battery can store,” Akshay Singhal, founder of Log 9 Materials, said in an interview. “So, earlier if the storage capacity was for five hours, it can now run for 6.5 to 7 hours.”
Mr. Singhal added that his company had achieved a 35% increase in the longevity of the batteries. “And the potential for this is a 50% increase in capacity, and a 40% increase in the life,” he said. The breakthrough, in an area that has not seen a change in the materials used in the last 30 years, comes with the use of a form of carbon called graphene. Mr. Singhal, a graduate of IIT Roorkie, said that Log 9 Materials started as a graphene and nanoparticles manufacturers, but quickly morphed into a product manufacturer since “it makes more sense if there are first products in the market that are graphene based before the market for the material picks up.”
“Graphene is a very thin material,” he added. “And as thin as a material is, the more is its capacitance (ability to store an electrical charge). Graphene is a single layer of atoms closely placed together. It’s the thinnest you can get. It is also very conducting, so not only can you can store more charge, but you can withdraw it at a much higher rate.”
