Some batteries use graphene in peripheral ways - not in the battery chemistry. For example in 2016, Huawei unveiled a new graphene-enhanced Li-Ion battery that uses graphene to remain functional at higher temperature (60° degrees as opposed to the existing 50° limit) and offer a double the operation time. Graphene is used in this battery for
Graphene batteries are a type of battery that utilize graphene as a component in the electrodes. Processing graphene into electrodes improves batteries due to graphene''s outstanding electrochemical properties and unique combination of large surface area, high electronic conductivity and excellent mechanical properties.

Scaling this method may help to bring the
Graphene improves the chemistries of both the cathodes and anodes of Li-ion batteries so that they hold more charge and do so over more cycles. Two major methods of using graphene as an anode involves the use of graphene as an additive in
Compared to magnesium-air, aluminum-air, and zinc-air batteries, it is more expensive to produce. While aluminum-air batteries cannot be recharged, lithium-air batteries have superior reversibility than zinc-air and magnesium-air batteries . Electrodes made of graphene have recently been used as effective electrodes for metal-air batteries. To
Could the use of graphene mean we see batteries being used in new settings? Yes, that''s possible – graphene can definitely enable new applications that don''t exist with the current lithium-ion battery technology.
Graphene-based electrodes have shown themselves to be a lot better at conducting electricity than the electrodes currently used in mass-produced lithium-ion batteries other words, they are more
Here, the scientific gap between graphene research and the key parameters in Li-ion batteries and beyond is discussed, such as the electrochemical window, the electrode surface area, and the
Even today, in 2021, graphene batteries aren''t on the market yet, in any major way. We do see, however, some niche adoption - for example, the use of graphene to enable novel battery casings, or extending the battery''s temperature range (see Huawei''s 2016 graphene battery announcement for example).
While graphene batteries have not yet reached widespread commercialization, battery breakthroughs are being reported around the world. Batteries serve as a mobile source of power, allowing electricity-operated devices to work without being directly plugged into an outlet.

What Are Sodium-Ion Batteries, and Could They Replace Lithium?
Graphene is an essential component of Nanotech Energy batteries. We take advantage of its qualities to improve the performance of standard lithium-ion batteries. In comparison to copper, it’s up to 70% more conductive at room temperature, which allows for efficient electron transfer during operation of the battery.
Graphene can improve such battery attributes as energy density and form in various ways. Li-ion batteries (and other types of rechargeable batteries) can be enhanced by introducing graphene to the battery's anode and capitalizing on the material's conductivity and large surface area traits to achieve morphological optimization and performance.
Although solid-state graphene batteries are still years away, graphene-enhanced lithium batteries are already on the market. For example, you can buy one of Elecjet's Apollo batteries, which have graphene components that help enhance the lithium battery inside.
Over the next few years, as the cost of graphene production drops, we expect to see more devices beef up their lithium batteries with this wonder material. One day soon, perhaps solid-state graphene batteries will become the next great revolution in power storage. That stuff inside of pencils is potentially a miracle for power storage.
