A lithium battery is nothing new, but when you infuse it with graphene, you will have a combination that charges faster, lasts longer, and has a lower temperature. The benefits are desirable and clear but the thing is, we have not seen any of these graphene lithium batteries in real life.
That will soon change as Real Graphene, a tech company based in Los Angeles as its CEO said such a battery is ready to be launched to the public.
Graphene Is No Longer Future Tech
According to Samuel Gong, Real Graphene’s CEO, people tend to think that graphene is the material of the future but it is not. The company’s batteries are fast charging and long-lasting, and they are here now.
On average, a phone battery takes 90 minutes to recharge, sometimes it is a bit quicker. With a cell produced by Real Graphene, you have to wait for just 20 minutes to fully charge a 3,000mAh battery with a 60watt charging brick.
Another advantage of this cell is longevity. They can last for 1500 cycles of charges. Last but not least, the cell is cooler so it is much safer to be around it.
Gong explained that to have these benefits, the company mixed graphene to the lithium battery. According to him, graphene has proven itself to be an amazing electricity and heat conductor. Lithium does not react well when you make it carry lots of energy or when you want to draw a large amount out.
In the company’s cells, graphene is added in two different ways, one is to mix with lithium and the other is to make a sheet of the material and add to the lithium battery. The material acts as a conductor of electricity and the best part is, it does not emit lots of heat.
Real Graphene provides not only the batteries but also the special chipset needed to charge them.
The sheet form of graphene is expensive to manufacture, the cost that the consumers will have to pay for. Each sheet needs $25 to make and some years back, you will have to spend $300,000 for one kilogram of the material.
A kilogram is not very much but it can go a long way in producing batteries. Graphene is not heavy and each sheet is just 5-atom thick, so manufacturers do not have to put much in one battery.
While the cost has reduced a lot in the last few years, the process of making graphene sheets is still complex. This is the reason why many batteries out there, which advertise themselves as carrying graphene, actually makes use of graphite, thus unable to deliver these above benefits.
It was not until recently that Real Graphene started manufacturing its batteries and some other manufacturers are testing them. The next step is for a company to embrace the tech and actually add a graphene-enhanced battery to a smartphone.
For Real Graphene, it is easy to scale up their production as they are the one that makes the material, so they can use someone else’s facility or collaborate with another battery making firm.
When it comes to size, a graphene battery will be 100% identical to the ones we are using today but the price will definitely be different. An estimation suggests that such a battery will be around 30% more expensive than its conventional counterpart.
This might deter some users but a lot more will be willing to pay a little extra to have a battery that charges faster and can work for a long time before needing to be replaced.
