Role of Graphene batteries in accelerating electrification of transportation.

Transport accounts for about 20% of global GHG emissions and 75% of this is from road transport. Therefore, electrification of transportation industry has the potential to reduce greenhouse gas emissions significantly. However, the EV industry has slowed down recently due to several challenges such as supply chain constraints, higher cost of ownership, lack of charging infrastructure, performance related issues such as longer charging time and range anxiety.

The existing Lithium-ion chemistries provide economical but sub-optimal solutions. While the LFP and NMC batteries helped in kickstarting the EV revolution, it won’t be enough to accelerate electrification of transportation industry. The industry is in search of an ideal chemistry that addresses the issues highlighted above and graphene-based battery technology has emerged as a viable alternative.

Graphene, because of its unique electro-mechanical properties solves most of the problems inherent in traditional Lithium-ion chemistries. Because of extremely high surface area, use of graphene facilitates higher energy storage capacity for the same amount of weight of the battery addressing customer hesitation related to range anxiety. Additionally, far superior electrical conductivity allows these batteries to recharge much faster thus saving time. 

As graphene batteries offer longer range, the demand of charging infrastructure gets moderated. With extremely safe operation and longer life, graphene batteries offer higher life-cycle value to the customer thus alleviating concerns related to cost of ownership.

– Charging time of less than 20 min for 100% SOC
– Lifecycles in the range of 4000-6000
– 1.5-2X range for same battery capacity.
