CR2450 battery

Why is it difficult to make breakthroughs in CR2450 battery technology?

If you only look at CR2450 battery technology, you will find that batteries can only increase a certain amount of storage in the past decade, but it is very difficult to make a completely revolutionary breakthrough in materials. Therefore, you will see that the power of mobile phone batteries is constantly increasing, but the increase is also very small, which is far from comparable to the development of chips and screens. Even in CR2450 battery technology, many people feel that CR2450 battery technology is stagnant and difficult to break through. From the last century to now, batteries have only made breakthroughs from the original nickel-cadmium batteries to lithium batteries.

Compared with nickel-cadmium batteries and lithium batteries, there are actually many differences. For example, the biggest advantage of lithium batteries is that they can be charged frequently, and the storage capacity has also been greatly increased. As long as it can be ensured that there is always power in the CR2450 battery storage CR2450 battery, the life of the lithium CR2450 battery can basically be extended. The charging mode of nickel-cadmium batteries is discharge and recharge, and there is a memory effect. With the development of time, people have now discovered a new storage material in CR2450 battery technology, which is graphene.

The storage capacity of graphene is one order of magnitude higher than that of lithium batteries. Samsung's graphene CR2450 battery is said to be able to store 5 times the amount of lithium batteries. Currently, only Samsung has adopted this graphene CR2450 battery, and mass production is also a problem. It is still difficult to say whether it is a real graphene CR2450 battery. The graphene mentioned by Huawei is nothing more than a lithium CR2450 battery plus graphene technology. In essence, it is a lithium CR2450 battery. According to Moore's Law, 2 years is a cycle. The number of transistors in an integrated circuit will double, but the CR2450 battery power will not increase at such a multiple. So why is the development of CR2450 battery technology so slow and difficult to break through?

The reason is still because of the physical limitations of nature. The difficulty in breaking through CR2450 battery technology is that each new electrode will cause more safety problems, such as explosion, short circuit or instability of the CR2450 battery itself. Many scientists have thought of many ways, but they can't break through this technical limitation anyway. Some scientists plan to add silicon electrodes in the laboratory to solve the safety problem, but unfortunately the result is also a failure. Therefore, graphene is indeed a development direction for batteries at present, but graphene is not mature in terms of mass production or technology, and the cost is very high. Graphene cannot increase the capacity of batteries.

The biggest feature of graphene is its conductivity. If it wants to become a revolutionary material that can subvert the capacity of CR2450 battery materials, it still requires a breakthrough in physics. Only by achieving more breakthroughs in basic disciplines can we develop better batteries through technology, which can truly change the CR2450 battery storage capacity and trigger a revolution.
