Connect a wire from the 12V output end of the transformer to the positive (or negative) end of the rectifier diode and wrap the connection head with insulating tape. Connect the other wire at the 12V output end of the transformer to the positive (or negative) end of the capacitor. Connect the...

To create a self-made 12V battery charger, you first need a circuit diagram of the 12V charger. If there is a diagram, it is easy to make. Following the diagram can provide a clear and convenient way to start making. Prepare the necessary materials for production. Firstly, o...

Due to the significant difference between the method used during detection and the actual situation in the battery, it is not particularly reasonable to compare the puncture strength of the two types of separators directly. However, when the microstructure is fixed, the ones with high puncture...

③ Wettability To ensure that the internal resistance of the battery is not too high, it is required that the separator can be completely soaked by the electrolyte used in the battery, which is related to the separator material itself and the surface and internal microstruct...
