Smartphones are getting faster and more capable with each passing year. But one aspect that has barely seen any changes is the battery technology. Most devices still rely on the tried and tested lithium-ion cells, however, graphene batteries could be the game-changer we’ve all been waiting for. So here are 3 ways it can revolutionize smartphones in the near future.
1. Faster Charging Speeds
One of the biggest advantages of graphene batteries is their ability to charge significantly faster than traditional lithium-ion batteries. Unlike most smartphones with lithium-ion batteries that take an around to fully charge even with fast charging, graphene batteries can be fully charged in mere minutes.
There have been demonstrations where graphene batteries being powered up with great speeds. Furthermore, unlike current fast charging technology, which can lead to battery life degradation over time, graphene’s high thermal conductivity helps reduce heat build up. In other words, graphene makes charging not only more efficient but safer as well.
2. Increased Energy Density for Longer Battery Life
The latest flagship smartphones with lithium-ion batteries that use silicon-carbon composite materials for higher battery capacities thanks to improved density. But graphene batteries boast much higher energy density right off the bat. Meaning, smartphones with this technology can store a lot more power for the same physical size as the current lithium-ion cells.
This also has many advantages with smartphones easily lasting more than a day with a single charge. Since graphene batteries can pack higher energy capacity, smartphones could also become slimmer and lighter without sacrificing battery life.
3. Longer Battery Lifespan
Battery degradation is a major issue with lithium-ion batteries as they lose capacity over time, requiring more frequent replacements. On the other hand, Graphene batteries, offer a much longer lifespan. A typical lithium ion battery can offer up to 500 to 800 charging cycles. However, graphene batteries can last well over 1,500 charge cycles before seeing any significant degradation.
This means that users who use their phones for multiple years need not worry about replacing batteries or battery life issues. Longer lasting batteries also go a long way in producing less electronic waste, which means that it is more sustainable and eco friendly as well.
4. Conclusion: The Future of Smartphone Batteries
To sum things up, Graphene batteries have the potential to revolutionize the smartphone industry with ultra fast charging that could take mere minutes, extended battery lifespan for reduced waste, and higher energy efficiency that could make battery life longer and smartphones thinner. Unfortunately, the technology is still too expensive to use as a commercial product, but the technology is still in development.
