Here are the specific reasons why the car key lights up red: Normal phenomenon: For some car models, pressing the car key will cause it to light up red, such as the Arrizo 5. Accompanied by the car failing to start and the dashboard not lighting up: If the car key lights up red and is accompanied by the car failing to start and the dashboard not lighting up, the red light on the car key is due to the car battery being dead. This may be caused by leaving the headlights on when locking the car, leading to battery drain. Replacing the battery can solve the problem. Red backlight: It can be confirmed that the car key has been stained with color. If the car key cannot be used normally, it is recommended to use the mechanical key to drive first.

What Materials Are Used in New Energy Batteries?

New energy batteries primarily consist of lithium manganese oxide, lithium iron phosphate, and ternary materials. Below are the relevant introductions: 1. Lithium Manganese Oxide: Lithium manganese oxide batteries are cost-effective and feature good safety and low-temperature performance as cathode materials. However, the material itself is not very stable and tends to decompose, producing gases, hence it is often used in combination with other materials. 2. Lithium Iron Phosphate: Lithium iron phosphate ion batteries offer excellent thermal stability, safety, low cost, and long lifespan, but have low energy density and are sensitive to low temperatures. The internal chemical composition of these batteries only begins to decompose at temperatures between 500-600°C, and they do not burn or explode under conditions such as puncturing, short-circuiting, or high temperatures.
