1. Main components of APM flight control battery
APM flight control systems usually use lithium polymer batteries (LiPo) as power sources, whose core components include positive electrode materials, negative electrode materials, electrolytes and separators. The following are the main components of LiPo batteries and their functions:
| Ingredients | Material | function |
|---|---|---|
| positive pole | Lithium cobalt oxide (LiCoO₂), lithium manganese oxide (LiMn₂O₄), etc. | Provide lithium ions and participate in electrochemical reactions |
| negative pole | Graphite, silicon-based materials | Store lithium ions and generate electric current |
| electrolyte | Organic solvents (such as carbonates) and lithium salts (such as LiPF₆) | Conduct lithium ions to achieve charge transfer |
| diaphragm | Polyethylene (PE) or polypropylene (PP) | Isolate the positive and negative poles to prevent short circuit |
2. The relationship between hot topics on the Internet in the past 10 days and APM flight control batteries
