1s lipo battery cell design table is one of the necessary tools for engineers who are developing materials for cell product development. The format of the design table is often different for each company, and even there are many kinds of design tables in a company.
The design table understood by CNHL is composed of three equations: the capacity equation (this article about the capacity of lipo battery has a detailed introduction, and the required partners can Click to read: The reason for the capacity of 6s lithium battery is a formula to understand!), volume equation, N/P ratio equation. Where capacity and volume are defined by the customer or by the process. The 1s lipo battery N/P ratio equation is explained as follows:
The same stage: 1s lipo battery charging and discharging has two stages, corresponding to different gram capacities, one is the first charging stage, and the other is the discharging stage, corresponding to the (first) charge N/P ratio and discharge N/P ratio respectively.
Regarding the discharge of lipo battery, the following article introduces the knowledge of self-discharge of lipo battery in detail. Interested partners can click to read:
lipo battery 3s self-discharge dry goods!
We know that the 1s lipo battery material has the first effect, which is the first (Coulomb) efficiency, that is, the first charge-discharge capacity ratio of the 1s lipo battery.
During the first charging process of the 1s lipo battery, the SEI film is formed on the surface of the material, the defect position of the material is reacted, the impurities in the material are also reacted, etc., resulting in the first charge capacity > the first discharge capacity > the discharge capacity after aging.
Although after aging and subsequent charge-discharge cycles, the discharge capacity of the 1s lipo battery still decays, but a large number of reactions have been completed in the early stage.
There are differences in the gram capacity of the two stages, one is the gram capacity of the first charge, and the other is the gram capacity after the first effect. Mixing them will cause the design of the 1s lipo battery to fail.
Same condition: The same condition is also relevant for gram capacity calculation. This condition refers to the same test conditions, such as temperature, magnification, voltage range, etc.
If the gram capacity test conditions of the positive and negative electrodes of the 1s lipo battery are different, using the same formula will also cause the design to fail.
Directly opposite: We need to calculate the area density, which is the meaning of being right. But what if the shape of the pole piece of the 1s lipo battery is bent and deformed? That is, when the outer ring shrinks and the inner ring stretches, we use the curvature to correct the value of the surface density, which is why the cylindrical 1s lipo battery has yin and yang surfaces during the coating process.
