Project scope:-

Graphene, a sheet of carbon atoms bound together in a honeycomb lattice pattern, is hugely recognized as a “wonder material” due to the myriad of astonishing attributes it holds. It is a potent conductor of electrical and thermal energy, extremely lightweight chemically inert and flexible with a large surface area. Andre Geim and Konstantin Novoselov are two winning Nobel Prize in physics researched groundbreaking experiments regarding two dimensional material of grapheme (Nai-Chang, 2017)

Higher temperature (60° degrees as opposed to the existing 50° limit) and offers a longer operation time - double than what can be achieved with previous batteries and making safer for electric cars, mobile phones, laptops and notable areas, this will reduce the carbon footprint of current vehicles and It is also considered eco-friendly and sustainable (DesigningBuildings, 2018)

Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state (vapor) to a solid state on a substrate. The copper layer is used as base layer and spread up multilayered grahene and then mixed with methane CH4 in room temperature, in minimum amount of time will get high quality graphene with honeycomb structures (PECVD, n.d.)

LFP (Lithium Iron Phosphate) batteries are a kind of rechargeable Li-ion battery. It has a lower energy density than other Li-ion batteries but a higher power density (an indicator of the rate at which energy can be supplied by the battery). Enhancing LFP cathodes with graphene allowed the batteries to be lightweight, charge much faster than Li-ion batteries and have a greater capacity than conventional LFP batteries (Lung-Hao, 2013)

Samsung advance institute of technology (SAIT) is has used the graphene in lithium ion batteries for upcoming Samsung S10 mobile with full charge time in almost five time (5X) fast charging, while capacity is boosted by 45% and it can sustain in 60 degree Celsius, the batteries are more thinner and lighter with great capacity (Jung, 2017)
