Lithium-ion batteries are a highly representative rechargeable category within the lithium battery family. Their core design cleverly avoids the issue of metallic lithium dendrite formation.

In modern energy storage systems, battery cells, battery modules, and battery packs form a three-tier structure ranging from basic energy storage units to end-use application systems.

Primary lithium batteries, also referred to as lithium primary cells, are a key branch of lithium batteries.

Based on the core characteristics of battery packaging forms, this article analyzes the characteristics, advantages, and selection logic of lithium batteries suitable for UAV applications, starting from the mainstream packaging types.

Specifically, the hierarchy can be divided as follows: Chemical Batteries (general category) → Lithium Batteries (subset) → Lithium-Ion Batteries (subtype) → Lithium Polymer Batteries (improved type of lithium-ion batteries). Additionally, lithium batteries also include other subtypes, such as lithium metal batteries.

The packaging form of a lithium battery is crucial for its adaptation to different application scenarios, which is primarily determined by application requirements, cell performance, and cost control.
