| The actual lipo battery 4s contain electrolyte and graphite. Among them, graphite has a layered structure, so the separated lithium ions can be easily stored there. The electrolyte between the graphite and the metal oxide in the lipo battery 4s acts as a protection, it only allows lithium ions to pass through, not electrons. When a power supply (electric field) is applied, the positive electrode of the lipo battery 4s power supply obviously attracts electrons from the lithium atoms of the metal oxide due to the attraction of opposites, and pushes these electrons to flow along the external circuit and reach the graphite layer of the lipo battery 4s. Note that these electrons cannot flow through the electrolyte. At the same time, the positively charged lithium ions of the lipo battery 4s will also be attracted to the negative electrode and flow through the electrolyte to reach the graphite layer. At this time, the graphite layer contains a large amount of lithium ions and electrons. These ions and electrons are lithium atoms, but because lithium atoms are unstable, they exist in the form of lithium ions and electrons. Once all the lithium atoms in the metal oxide of the lipo battery 4s reach the graphite layer, the lipo battery 4s is fully charged. At this point, the unstable state of the lithium atoms is like a small ball on the top of the mountain. Once the power is removed and the load is connected, the lithium atoms return to a stable state as part of the metal oxide. Due to this tendency to stabilize, the electrons lithium back to the oxide through the load, and the lithium ions pass through the electrolyte back to the oxide, like a small ball sliding down a mountain top, and finally the lithium ions and electrons combine to form lithium atoms Fixed in lipo battery 4s metal oxide. Note that graphite does not play a role in the chemical reaction of the lipo battery 4s, it is only a storage medium for lithium ions. If the internal temperature of the lipo battery 4s rises due to some abnormal conditions and the electrolyte dries up, the lithium ions and electrons all run to the oxide along the same path, which is equivalent to a short circuit between the anode and the cathode, which may lead to fire or explosion . In order to avoid the above situation, an insulating layer, called a separator, is placed between the electrodes of the lipo battery 4s. Due to its micropores, the separator is permeable to lithium ions, but electrons cannot. In the actual lipo battery 4s, graphite and metal oxide are coated on copper foil and aluminum foil, respectively, the foil acts as a current collector here, and the positive and negative electrodes can be easily removed from the collector, where the copper foil leads out the negative electrode , the aluminum foil leads to the positive electrode.
