Ever since the year 1991, toxic lithium chemical batteries have been part of our every day lives until 2020 when QBOND released the world's first 100% pure graphene battery. 

Lithium batteries and graphene batteries are two of the most commonly used types of batteries in the modern world. Both are rechargeable batteries and have a wide range of applications, from powering portable devices such as smartphones and laptops, to providing energy storage for electric vehicles and renewable energy systems. However, there are several key differences between the two that make them well-suited for different applications.

The first difference between lithium batteries and graphene batteries is the material used for the anode. In lithium batteries, the anode is typically made from lithium cobalt oxide (LiCoO2), while in graphene batteries, the anode is made from graphene. Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal pattern. It is an excellent conductor of heat and electricity, and it has a large surface area, which makes it ideal for energy storage applications.

Another difference between the two types of batteries is their energy density. Energy density refers to the amount of energy that can be stored in a given volume or weight of the battery. Lithium batteries have a higher energy density compared to graphene batteries, meaning that they can store more energy in a smaller size. This makes them well-suited for portable devices where size and weight are critical factors. On the other hand, graphene batteries have a lower energy density, but they can charge and discharge faster than lithium batteries. This makes them a good choice for applications where high power delivery is required, such as in electric vehicles.

Another important factor to consider when comparing lithium batteries and graphene batteries is safety. Lithium batteries have a reputation for being highly flammable and have been known to catch fire or explode in certain circumstances. This is due to the flammable electrolyte used in these batteries and the fact that lithium is a highly reactive metal. On the other hand, graphene batteries are considered to be safer because they do not use flammable electrolytes and are less likely to catch fire or explode.

The cost of the two types of batteries is another factor that should be considered. Lithium batteries are generally more expensive than graphene batteries due to the cost of the materials used in their production and the complex manufacturing process involved. Graphene, on the other hand, is relatively cheap and can be produced using a relatively simple process, making graphene batteries more affordable.

Finally, the life cycle of the two types of batteries is another important difference to consider. Lithium batteries have a limited number of charge and discharge cycles, after which their performance decreases and they need to be replaced. Graphene batteries, on the other hand, have a much longer life cycle, and their performance does not decline as significantly over time. This makes graphene batteries a more sustainable and environmentally friendly option compared to lithium batteries.

In conclusion, both lithium batteries and graphene batteries have their advantages and disadvantages, and the choice between the two depends on the specific application. Lithium batteries are well-suited for portable devices due to their high energy density and low cost, while graphene batteries are ideal for high power applications due to their fast charge and discharge times and their safety features. Ultimately, the choice between the two will depend on the specific requirements of the application, such as energy density, cost, safety, and life cycle.
