Importance of Battery ConsistencyAug 12 , 2024The inconsistency of energy storage batteries mainly refers to the inconsistency of parameters such as battery capacity, internal resistance, and temperature. Our daily experience is that when two dry batteries are connected in positive and negative directions, the flashlight will light up, and we don’t consider consistency. However, once batteries are used on a large scale in energy storage syste...read more

Battery Charge and Discharge CurvesJul 19 , 2024During the charge and discharge process of the battery, as the charge and discharge depth changes, the voltage is also constantly changing. If we use capacity as the horizontal coordinate and voltage as the vertical coordinate, we can get a simple charge and discharge curve, which contains many clues about the battery's electrical performance. These curves drawn with the battery cell parameters su...read more

Why Monitor Dew Point in Lithium-ion Battery Workshop?Jul 08 , 2024The dew point is the temperature at which moisture condenses. When the water vapor content in the air remains unchanged and the air pressure is kept constant, the temperature at which the air is cooled to saturation is called the dew point temperature (Td), or dew point for short. It can also be understood as the temperature at which water vapor and water reach equilibrium. The difference between ...read more

Key Points of Lithium-ion Battery Areal Density DesignJun 24 , 2024Areal density（mg/cm2）：Areal density refers to the mass per unit area, which in this case is (the mass per unit area ofthe region ignoring the volume). Compacted density（g/cm3）：The compacted density indicates the mass contained in a unit volume, which has a lot to do with the properties of the material itself. Thickness：The total thickness of the material and the foil is generally expressed in micr...read more

Lithium-ion Battery Winding Process GuideJun 20 , 2024The winding process of lithium-ion batteries is to roll the positive electrode sheet, negative electrode sheet and separator together through the winding needle mechanism of the winding machine. The adjacent positive and negative electrode sheets are isolated by the separator to prevent short circuit. After winding, the jelly roll is fixed with a termination tape to prevent it from spreading, and ...read more
