What does battery energy density refer to?

　　Energy density refers to the amount of energy stored in a certain space or mass of matter. The energy density specific energy of a rechargeable battery is the electromagnetic energy released by the volume or mass of the rechargeable battery. The number of times the rechargeable battery is more powerful than the energy battery; the charging and discharging service platform/rechargeable battery thickness/total width/rechargeable battery length, the basic component is wh/kg (wh/kg).

　　The greater the specific energy of a rechargeable battery, the more power it can store per unit volume.

　　Now people have understood that the most important breakthrough point for the battery industry and even the pure electric vehicle manufacturing industry, but it is difficult to upgrade!

　　Proportion of inactive materials (except conductors, etc.) in typical rechargeable battery designs

　　It is understood that the specific energy of a rechargeable battery is determined by the positive and negative aspects of the rechargeable battery. However, only the positive and negative specific raw materials cannot guarantee that the rechargeable battery can generate electricity. There are many inactive substances, such as conductive neutralizers, special Powder intermediate adhesive, protective film, anode foil, insulation layer fixing tape, aluminum plastic film or steel aluminum shell, etc.

　　Most of us inadvertently ignore the composition of these chemicals and gain more energy from the network spray than objective fact. In fact, these are crucial. In terms of technological development in the past decade, the key to improving the battery power ratio is to rely on increasing the usage of active materials.

　　The necessity of improving the specific energy of power lithium batteries

　　In a certain practical sense, power lithium batteries replace the car's fuel tank. The capacity of the vehicle can be expanded, but the overall design of the vehicle is fixed and will not change. Even if a pure electric vehicle product is developed, the internal structure of the power lithium battery will be affected. The rational distribution of space is just a fixed position between the front and right axles.

　　Without changing the reasonable indoor space layout, increasing the total capacity of rechargeable batteries is a basic issue in dealing with durability. Basically, from 2013 to now, the mileage of domestic new energy vehicles has increased from 150 kilometers to 400 kilometers, lagging behind the latest mileage. Power lithium batteries usually require a lighter total weight and a larger battery charge capacity, which is the key to upgrading.

　　Essentially, lithium-ion batteries refer to the overall range of rechargeable batteries that use positive ion implantation as the positive material. Whether it's lithium ion or lithium phosphate. The overall charging process of the battery is basically the same. The difference lies in the different trends of different materials pursuing perfect characteristics.

　　Lithium batteries are composed of positive lithium battery electrolyte and negative phase, and the main raw material is lithium metal chemicals. When the battery is charged, the battery is converted into a lithium-ion battery, according to which the electrolyte solution is converted to the negative level of the rechargeable battery and the negative material is put in. When charging and discharging, the lithium-ion battery with negative material returns to the positive electrode according to the flow of electrolyte. The more lithium-ion batteries that return to the positive potential, the greater the battery capacity.
