The basic structure of modern batteries includes three elements: positive electrode, negative electrode, and electrolyte. As a type of battery, lithium-ion batteries also have these three elements. General lithium-ion technology uses liquid or inorganic colloidal electrolytes, so a sturdy shell is required to accommodate combustible active ingredients, which increases the weight and cost of the battery and limits the flexibility of size and shape. Generally speaking, the small thickness of liquid lithium-ion secondary batteries is 6mm, which can be difficult to reduce further.

　　The so-called polymer lithium-ion battery uses polymer materials as its main battery system in at least one or more of these three main constructions.

　　The new generation of polymer lithium-ion batteries has already achieved a high degree of polymerization, so they can be thinly shaped (very thin by 0.5 millimeters), arbitrarily shaped, and shaped, greatly improving the flexibility of battery design. Therefore, they can meet product requirements and be made into batteries of any shape and capacity.

　　Meanwhile, the unit energy of polymer lithium-ion batteries has increased by 50% compared to current general lithium-ion batteries, and their capacity, charging and discharging characteristics, safety, operating temperature range, cycle life, and environmental performance have significantly improved compared to lithium-ion batteries.
