Graphene Batteries vs Lithium-ion Batteries

by Luther B. Technology Writer

Phone batteries are often a frustrating element of mobile phones. As mobile phone technological features advance, the battery life of mobile phones seems to decrease. Phone batteries haven’t advanced that much in recent years, whereas mobile phones have. This means the power of phones is outweighing the capacity at which the batteries can function at.

Samsung however, is planning on switching from traditional lithium-ion batteries, to graphene-powered batteries. These graphene batteries will charge 5 times faster than lithium-ion batteries and will be able to hold up to 45% more capacity. They’ll also be smaller, slimmer whilst having a similar surface temperature. Although, these batteries are thought to be expensive and won’t be available on the market until 2021.

Phone batteries are a frustrating element of mobile phones. As technology advances, the battery life of mobile phones seems to decrease. This is because the power at which mobile phones need to operate is outgrowing the capacity at which batteries can function. Samsung however, is planning on switching from traditional lithium-ion powered batteries, to graphene, in an attempt for the batteries to keep up with modern mobile phones.

Comparing graphene batteries 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. There are some graphene power banks as well as present in the market. 


Graphene batteries are said to be the absolute alternative to our current-gen lithium-ion batteries. Graphene batteries are 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.

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.”
