Has the development of lithium battery technology slowed down, or is the technology stagnant?

With the development of science and technology, people’s reliance on portable electronic devices is increasing. The wide application of lithium-ion batteries also temporarily meets the daily battery life requirements of electronic devices. However, with the increase of functions, the battery life of lithium batteries is no longer necessary. However, the slots are full, is the technology of lithium batteries stagnant? In fact, this is not the case. In the past 10 years, lithium-ion battery technology has been progressing, but the speed of development has not caught up with the demand for power consumption of new technology products. Has the development of lithium battery technology slowed down, or is the technology stagnant? Nowadays, the commonly used lithium-ion battery is a very mature technology and has been applied for 20 years. Relying on the movement of lithium ions through the electrolyte between the lithium cobalt oxide positive electrode and the carbon negative electrode to achieve charging and discharging, the basic principle is very clear, and the room for improvement in battery performance is limited. The latest research also focuses on the development of new positive and negative electrode materials to achieve stable charge and discharge cycles. There are many reports on scientific research progress, but when it comes to commercial applications, the biggest problem is the high cost of preparation or stability problems. There are also some research and reports on graphene batteries, and more are hype about the concept of graphene. For example, there are now some research and reports on graphene batteries, but they are more hype about the concept of graphene. Graphene, a star material, is added to a lithium-ion battery in a small amount, and it can be regarded as a lithium-ion battery doped with graphene. Graphene is used in batteries to increase the conductivity of the electrolyte or directly blended into negative electrode materials. There are many similar reports of high performance. However, it is difficult to achieve breakthroughs in comprehensive performance, which is limited by the price and preparation process of graphene materials. In the short term, the application of pure graphene electrodes cannot be realized. In the long run, battery technology must have been advancing, and we look forward to new materials and technologies that can completely break through the battery bottleneck. As for some supercapacitors and nuclear batteries, these are not choices for our civilians and households for the time being. With the continuous development of new energy technologies in the past two years, especially the widespread application of photovoltaics and wind power, energy storage technology is becoming the next technological hotspot. I believe that in the near future, our mobile phones can completely realize long-term free charging applications. Let us look forward to it together!
