Battery is a portable power energy products, lithium batteries have appeared as early as in the last century, continuous optimization and development, is now a common category of battery products, lithium battery development history is a journey full of innovation and breakthroughs in science and technology. From the initial laboratory research to today’s wide range of applications, lithium batteries with its high energy density, long life and environmental protection and other characteristics, has become one of the indispensable and important energy sources in modern society.

As early as in the 1960s, Prof. John Goodenough of the United Kingdom discovered a new anode material – lithium cobalt oxide (LiCoO2) by chance when he was researching magnetic materials. This discovery laid an important foundation for the birth of lithium batteries. With high energy density and long life, LiCoO2 anode became one of the most commonly used anode materials in lithium batteries. Subsequently, Prof. Rachid Yazami of France and Prof. Stanley Whittingham of the U.S. proposed the anode materials for lithium-ion batteries – graphite and lithium titanate (LiTi2O4), and the ternary combination of anode and cathode material system for lithium batteries was gradually formed. The ternary combination positive and negative material system of lithium battery was gradually formed.

In the early 1980s, the commercialization of lithium batteries began to appear gradually. With the continuous progress of technology and market expansion, lithium batteries have been widely used in various fields. Especially in the field of consumer electronics, lithium batteries have become the ideal choice for smart phones, tablet PCs and other devices due to their high energy density and long life. In addition, lithium batteries also play an important role in electric vehicles, energy storage systems and other fields, providing strong support for the use of renewable energy and the stability of the power network.

However, the development of lithium batteries is not all smooth sailing. In the application process of lithium batteries, safety has been the focus of attention. In order to solve this problem, researchers have been exploring new materials and technologies to improve the safety performance of lithium batteries. For example, by improving the structure of the battery and the manufacturing process, to improve the battery’s ability to resist overcharging, overdischarging and short-circuit, etc.; the use of multi-layer structure and thermal isolation and other technologies to prevent the battery thermal runaway; at the same time, to strengthen the monitoring and management of the battery, and to detect and deal with the potential safety hazards in a timely manner.

In addition to safety issues, the cost of lithium batteries and environmental protection is also a key factor restricting their development. In order to reduce the cost of lithium batteries, researchers are committed to developing new production processes and materials to improve production efficiency and reduce material costs. At the same time, strengthening the recycling and treatment of waste batteries to reduce environmental pollution and resource waste is also an important direction for the sustainable development of lithium batteries.

With the progress of science and technology and market changes, the development of lithium batteries is also constantly pushing forward. New positive and negative electrode materials, electrolytes and additives continue to emerge, providing more possibilities for lithium battery performance improvement and cost reduction. At the same time, the emergence of new battery technologies, such as solid-state batteries, also brings new opportunities and challenges for the development of lithium batteries.

Overall, the history of lithium battery development is a technological epic full of innovation and challenges. From the initial laboratory research to today’s wide range of applications, lithium batteries have provided a powerful impetus for the development of modern society with their unique advantages. In the future, with the progress of science and technology and changes in the market, lithium battery will continue to play its important role and make greater contributions to the sustainable development of human society.
