1. The initial breakthrough of lithium batteries. Research on lithium batteries began in 1912. However, the real breakthrough was in 1958. At that time, a graduate student at the University of California proposed the idea of using active metals such as lithium and sodium as the negative electrode of the battery. After that, people began a comprehensive study of lithium batteries. At the same time, new progress has been made in the field of lithium battery materials such as electrolytes, further promoting the development of lithium batteries. After years of exploration, lithium battery positive and negative electrode materials and electrolytes and other related materials have been constantly updated and iterated. New materials give lithium batteries better performance, further promoting the application and promotion of lithium batteries.
2. From primary battery to secondary battery
early lithium batteries were mainly primary batteries. The chemical energy in the battery was converted into electrical energy and irreversible, that is, a non-rechargeable battery. With the continuous research on new materials and the continuous advancement of technology, the functions and performance of lithium batteries are constantly upgrading and changing. In the late 1970s, the concept of lithium-ion battery was proposed. Researchers used two different embedded compounds as the positive and negative electrodes respectively. After continuous experiments and debugging, the secondary battery was born, which is the early "rocking chair battery". The charging and discharging function was realized through the back and forth movement of lithium-ion between the positive and negative electrodes, thus pushing battery application to a new height. In subsequent developments, electrode materials and electrolyte materials continued to change until the negative electrode materials were replaced by carbon materials with more suitable performance and production, which started the industrial revolution of lithium batteries.
3. The leap of lithium battery applications
The application of lithium battery has gradually started a gorgeous turn after completing the qualitative leap of rechargeable and dischargeable, especially the large-scale production of lithium-ion batteries started in Japan in 1991. At the same time, it is used in mobile phones, which is of milestone significance to the popularization and promotion of lithium batteries. In the next few decades, the focus of lithium battery research and development began to shift toward lighter, smaller, and higher energy ratios to meet the needs of increasingly developed small-scale portable electronic devices, especially the development of mobile communication device , which has become a strong promoter to the popularization of lithium batteries. The lithium industry has also become one of the most popular industries driven by consumer demand.
4. The new journey of lithium batteries
In recent years, new energy has begun to become the next industry that hopes to change the world's development process. New energy has shown unprecedented potential under the pursuit of the goal of highly consistent with mankind's vision of energy utilization transformation. Among them, new energy vehicle is the most popular and representative industry among them. The status of power lithium batteries in the energy storage field has also begun to be sought after, further consolidating the status of lithium batteries. Although people have begun to study alternative products of lithium batteries, from the moment, most of the relevant research is still in the experimental stage, and it will take some time to truly replace lithium batteries.
Conclusion of this article
From the development of lithium battery applications, we can see that a thing needs to go through a long process from research to wide application, requires the joint promotion of all aspects of conditions and factors, and even requires generations of continuous research, technological improvement, and production progress to achieve the fruits of today's industrial prosperity. A mature industrial system and application have never been achieved overnight. It requires accumulation day after day, exploration, patience and perseverance, and continuous application of technology to benefit mankind. The "big drama" about lithium will continue to be staged in the future, let us wait and see and look forward to its arrival together.
