Solid Polymer Electrolytes (SPE), also known as ion-conducting polymers or solvent-free polymer electrolytes, are a class of solid-state ionic conductors formed by using high molecular polymers as the matrix and compounding them with metal salts (such as lithium salts and sodium salts).

Prismatic lithium batteries are one of the important packaging types of lithium-ion batteries. They have a rectangular or square shape and, together with cylindrical lithium-ion batteries (such as models 18650 and 21700) and pouch lithium-ion batteries, constitute the mainstream categories of lithium-ion batteries.

Button-type lithium batteries are small-sized lithium batteries with a disc-like, button-like shape.

A cylindrical lithium-ion battery is a rechargeable lithium-ion battery with a cylindrical shape. It uses lithium as the core energy storage carrier and is widely applied in various fields due to its long service life and high energy density.

Soft-pack lithium batteries for drones, which use aluminum-plastic composite film as the packaging material, fall under the category of lithium-polymer batteries.

Cylindrical lithium-ion batteries for UAVs are cylindrical-shaped batteries that utilize lithium-ion technology.
