Comparing graphene battery with Lithium-ion Battery technology shows why battery users are excited about a technology that offers a slimmer, smaller battery size, higher energy density and faster charging times than current batteries.
“Almost every portable electronic device today – be it our smartphones or electric vehicles come packed with the widely used lithium-ion batteries. They hold a limited charge, are quite bulky, need charging often and have a modest lifespan.
Graphene batteries are said to be the absolute alternative to our current-gen lithium-ion batteries. Graphene batteries are itself quite lightweight, advanced and powerful. Graphene has been found to be a superior material as it not only has higher electrical and heat conductivity, but it’s also quite lightweight, flexible, and durable. Thus, graphene batteries have been under development for many years now and are expected to go mainstream in the next couple of years.
The internal structure of a graphene battery is quite similar to that of a standard lithium-ion battery pack. You have 2 electrodes and an electrolyte solution to enable flow of charge, but there’s a notable difference here. One of the electrodes in graphene-based batteries, mostly the cathode, is replaced with a hybrid composite material (solid-state metal + graphene) used in place of a standard solid-state metal.
Key benefits of graphene battery technology include:
Smaller, slimmer battery: We have already discussed how graphene is lightweight. It’s when you stack 3 million layers of graphene is that you get 1 mm thickness. I mean, that should be enough to tell you that graphene batteries aren’t going to take much space in your future smartphone. It will allow manufactures to place higher capacity batteries in your phones, tablets, laptops, and more.
Higher capacity: Graphene has a higher energy density as compared to lithium-ion batteries. Where the latter is known to store up to 180 Wh per kilogram, graphene’s capable of storing up to 1,000 Wh per kilogram. So, you can have a higher capacity graphene battery pack of the same size as the lithium-ion battery.
Other benefits include faster charging times, thermal management and greater safety.
Graphene batteries are definitely the next big thing because carbon is in abundance as compared to Lithium, which is a rare metal.”
The rarity of litium is another reason why comparing the graphene battery with current lithium makes commercial sense.
