The safety requirements for carbon electrode materials and contents are mainly for hydrogen electrode materials. For example, if there is a slight error in the rigidity agent and chemical substances of high-purity polysilicon electrodes, the voltage will drop, or it will easily burn and explode.
Because the chargers in modern society are separated from the relatively more polluting carbon rods and made of plastic boxes to protect the power supply assembly, the inside of the charger is designed in strict accordance with safety standards. The current has been designed for safety, so there is no hidden danger of accidents. Of course, there may still be errors in the design, which may cause inconvenience to you. However, in real life, there is generally no hidden danger of accidents. This kind of personal design itself does not design the safety of the charger so high, and it is also tested by a third-party organization according to safety standards.
Lithium battery material is not like iron, it is a structural material, and only the weight affects the weight, if the material is not strong enough, it is easy to deform. It will not cause voltage changes or harm the circuit due to slight deformation (such as a short circuit causing a current dead circuit). Compared with the battery itself, it is placed on the head of the electrical appliance, and the voltage change is less, and naturally, there is no harm to it. Carbon batteries have experienced thermal expansion and thermal failure, the storage pressure will be high, and it is easy to foul, and the battery voltage is low, and it is easy to generate heat. None of this is a problem for ordinary monolithic metal machines, and the voltage variation on each core of the microcontroller is also very small.
This can all be tolerated. It's too complicated. I don't want to analyze the design of battery materials, which means going around. I want a result that is light in weight and does not require materials that generate heat. The thermal design generally refers to the safety design of temperature influence. However, carbon batteries do not consider this. If the voltage changes subtly over 200 degrees, the outer shell will corrode, and the heat dissipation of the entire battery will also be problematic. This is a matter of internal components. Just like college students who want to experiment, there are parameter control and experimental calculations, but they just care about what other people say.
Mobile games, chargers, mobile phones, lithium batteries, and mobile phones have different materials, capacities, protection voltages, etc., and they are essentially whole. The two materials are complex but there is no possibility of mutual interference, and it is difficult to deteriorate a large area after experiencing thermal expansion and thermal failure. It is no different from preparing different dishes all the time when cooking.
