On the one hand, the technology is still immature. On the other hand, the cost remains high. Furthermore, much work needs to be done in areas such as safety and stability. Moreover, even if graphene batteries are successfully developed and widely adopted, they may not necessarily be suitable for electric vehicles, replacing the currently popular lithium-ion batteries. Just as a special technology has many advantages, it cannot simply replace other types of power plants. Similarly, graphene batteries may not be suitable for electric vehicles. Only in suitable application scenarios can specific technologies maximize their advantages.
1. Graphene batteries need time to move from the laboratory to the market, and this process has not yet begun.
The transformation of scientific research results into market products takes time, and not every technology is suitable for large-scale commercialization. Currently, there is no consensus on what graphene batteries actually are.
Does using a tiny amount of graphene as an electrode material constitute a graphene battery? Currently, most batteries on the market that dare to claim to be graphene batteries, aside from scams, are essentially lithium-ion/lead-acid batteries that incorporate or use graphene. While the all-graphene battery of our imagination does exist, it remains only in the laboratory and is far from meeting industrialization standards.
Graphene's potential applications extend far beyond replacing traditional batteries. In fact, graphene may hold greater promise in novel flexible batteries, devices, displays, and catalysts. Considering the excellent overall performance, good capabilities, mature industry, and relatively low price of lithium-ion batteries, graphene is unlikely to replace them in the foreseeable future.
The actual value of a technology depends not only on performance but also on many other factors such as cost-effectiveness and stability. For graphene to one day surpass lithium-ion batteries and become the most suitable battery option for automobiles, it must demonstrate advantages in the laboratory that lithium-ion batteries cannot match, and then be heavily promoted by major manufacturers. Currently, graphene batteries are still very immature and have not shown any significant advantages over lithium-ion batteries. Therefore, graphene batteries do not even have the potential to replace lithium-ion batteries. Moving from the laboratory to the market takes time, and for graphene batteries, this process has not yet begun. Because a compelling reason for entering the market has not yet been found.
2. Graphene technology may be used to enhance lithium-ion batteries rather than replace them.
While graphene battery technology is a newer and potentially more powerful technology, lithium-ion batteries are the culmination of years of battery technology development. Lithium-ion batteries possess many advantages, which is why they have become the most mainstream automotive battery. Graphene technology has indeed provided a possibility for breakthroughs in battery technology, but it does not mean that graphene can completely replace lithium-ion batteries.
In the future, if graphene-related research matures and technological breakthroughs are achieved, the possibility of applying these findings to lithium-ion batteries to improve their performance is much higher than the likelihood of graphene completely replacing lithium-ion batteries. Every material has its own characteristics, and graphene's surface properties are greatly affected by its chemical state, resulting in numerous issues with stability, cycle life, and so on. If the pursuit of replacing lithium-ion batteries with graphene is deliberately pursued, it is highly likely that graphene batteries will be produced that are less practical than lithium-ion batteries.
