Lithium-ion batteries: the energy heart of modern technology

Time dates back to 1981, an epoch-making invention was born, that is the first generation of lithium battery patent issued. This milestone marks the dawn of modern lithium-ion battery technology. After 11 years of technology precipitation and market exploration, in 1992, lithium battery officially entered the mass production and civil market, quickly occupied the core position of portable electronic equipment, such as mobile phones, laptops, etc., become an indispensable partner in modern life.

In the 21st century, with the rise of electric vehicles and renewable energy, the demand for lithium batteries has exploded like a blowout, driving the rapid iteration and innovation of technology. From the initial exploration to the current wide application, lithium battery at an amazing speed from the laboratory to the global market.

Lithium battery family is huge, numerous members, diverse classification methods, to meet the unique needs of different fields. By shape, cylindrical, square and soft-pack lithium batteries, cylindrical batteries in power tools, and square batteries in electric vehicles and energy storage systems. Lithium batteries of different shell materials, such as steel shell, aluminum shell and soft bags, have their own characteristics and adapt to the safety and weight needs of different environments.

The diversity of cathode materials, such as lithium cobalt oxide, lithium manganese oxide, lithium nickel-cobalt manganese oxide and lithium iron phosphate, determine the energy density, safety and cost of lithium batteries, and become the key to technology selection. The differences in electrolytes, such as liquid Lithium Ion, polymer lithium ion and all-solid state lithium ion batteries, directly affect the performance and safety of batteries, and have become a hot topic of future technology exploration.

With its excellent performance, lithium battery has conquered consumer electronics, electric vehicles, industrial energy storage, medical electronics, aerospace and military equipment and other fields. In smart devices, lithium battery is the guardian of endurance; in electric vehicles, it is the engine of new energy vehicle revolution; in industrial energy storage, it is the wise man of power grid regulation; in high technology fields, such as medical care, aerospace, etc.

The performance parameters of lithium battery, just like its technical core, voltage and capacity, internal resistance and cycle life, working temperature range and discharge ratio, constitute a multi-dimensional perspective to evaluate its performance. These parameters not only reflect the power output capacity, charge and discharge efficiency and durability of the lithium battery, but also determine its performance under different environments and power requirements.

The safety testing and transportation of lithium battery, just like the combination of technology and art, needs both the rigor of science and technology and the delicacy of art. A series of rigorous safety tests, from electrical performance to mechanical, to environmental adaptability, ensure the safety performance of lithium batteries. In the process of transportation, follow the regulations of the International Air Transport Association (IATA) to ensure the safe transportation of lithium batteries, and become a perfect interpretation of technology and rules.
