A lithium-ion secondary battery (rechargeable lithium battery) is a highly efficient energy storage device that has revolutionized modern technology. It typically consists of an electrode assembly, a protective container, and an electrolyte. The electrode assembly includes two electrodes with opposite polarities separated by an advanced porous membrane separator.
Advanced Separator Technology
In high-performance secondary batteries, the separator often features a porous membrane containing engineered ceramic particle clusters. This porous film is formed by bonding these clusters with a specialized adhesive. Each particle cluster is meticulously formed by sintering, or by dissolving and recrystallizing ceramic particles. Because these ceramic materials possess a specific band gap and excellent thermal resistance, they drastically improve the safety and structural integrity of the battery.
The Evolution of Chemical Batteries
A chemical battery is a device that directly converts chemical energy into low-voltage direct current (DC) energy. The history of the battery spans over 200 years, dating back to Alessandro Volta’s invention in 1800. Prior to World War II, the market was dominated primarily by zinc-manganese dry cells and heavy lead-acid batteries.
Following the post-war technology boom in aerospace, mobile communications, and consumer electronics, the global demand for high-energy storage batteries skyrocketed. Because lithium has the lowest atomic mass and the highest electrode potential among all metal elements, batteries utilizing lithium exhibit exceptional characteristics, such as a high open-circuit voltage and a massive specific capacity.
The Rise of Lithium-Ion Secondary Batteries
In the 1970s, scientists developed the first disposable (primary) lithium batteries. By 1990, Sony launched the world’s first commercial lithium-ion secondary batteries. Driven by the rapid expansion of mobile communications and laptops, lithium-ion technology quickly replaced older nickel-cadmium (Ni-Cd) and nickel-metal hydride (NiMH) batteries as the premier high-energy power source.
Today, the specific capacity and cycle life of commercial lithium-ion batteries far exceed early industry projections, frequently surpassing thousands of charge cycles. This technology has expanded beyond small consumer electronics into heavy-duty electric vehicles (EVs) and grid-scale energy storage. Furthermore, innovations like solid polymer and ultra-thin plastic lithium-ion batteries are continuously entering the market, pushing the boundaries of lightweight, high-density energy storage.
