The increase in voltage can bring more capacity to the battery, longer battery life for terminal devices, and enhance the signal strength of communication devices. Taking the Samsung NOTE2 battery label as an example, 11.78Wh, 3100mAh and 4.35V, 3.8V and 11.78Wh represent the total energy of the battery, that is, how much electric energy is stored, which is a direct indicator of how powerful the battery is. The higher the value of the same battery, the more awesome the battery has. 3100mAh represents the capacity of the battery, 4.35V represents the charging cutoff voltage, 3.8V represents the platform voltage of the battery, and multiplying 3100 by 3.8 is exactly 11.78Wh. The former is an important sign to measure whether the battery (i.e. the positive material) is awesome or not. The larger the capacity, the more useful the battery is and the longer its battery life (for the same discharge current); The latter represents the cutoff voltage for battery charging. For batteries with the same positive electrode material, the higher the cutoff voltage, the higher the battery capacity, and the longer the battery life. Therefore, most manufacturers use cut-off voltages of 4.2-4.5V for lithium batteries, which are safe and reliable. The following 3.8V represents the voltage platform of the battery (positive electrode material), and the higher the platform, the higher the specific energy of the battery. Compared to previous batteries, which often had a platform of 3.7V, high voltage batteries had a platform of 3.8V. Although it only increased by 0.1, the energy capacity of the battery increased by 10%.
The main technology of high voltage lies in the use of specific cathode materials and conductive carbon materials with three-dimensional spatial conductive networks, and the addition of a small amount of wetting agent, lithium salt stabilizer, anode film forming additive, and cathode film forming protective agent to the electrolyte, enabling lithium-ion batteries to operate at higher cut-off voltages.
As the energy density gradually increases, the safety of lithium batteries is required to be higher due to the instantaneous increase in energy burst per unit space. Main technology: 1. Using a ceramic diaphragm, the ceramic material layer coated on the porous membrane substrate can improve the heat resistance of the diaphragm, while the adhesive polymer adhesive layer coated on the ceramic material layer can prevent internal short circuits caused by interlayer misalignment between the diaphragm and the electrode, enhancing the safety performance of the battery. 2. Using new electrolytes, positive electrode materials, additives, material systems, and other methods to improve battery safety.
