In terms of carbon electrode materials, lead should choose high-quality lead-acid battery shells. Lithium battery shells often have problems such as disconnection and shedding of the cladding, so the initial state of the battery cell is still the most important. The second is the problem of stroke and power. Generally, the average power of lithium batteries is around /min.

For lithium batteries, the longer the range, the better. For example, 1200-1300 mAh is the range, and 1200-1400 mAh is the peak; the higher the conversion rate, the better. Many universities have studied this but the conclusions are not uniform. If necessary, you can Take a look at this article: Recommended 13-22 mA load for the best battery output power and actual utilization

From the perspective of design and manufacturing, it is the best to use, with good capacity and conversion rate

If you only need to know the utilization rate and conversion rate of the battery cell, don't worry about other characteristic parameters. However, in some special cases, there will be slight deviations in utilization and conversion rates.

The stroke is the charge and discharge rate of the positive and negative poles of the battery. The shorter the charge and discharge rate, the smaller the voltage loss. The maximum output power of the battery is related to the nominal diameter of the cell, but there is a large difference in actual utilization.

Generally speaking, the higher the conversion rate, the better, and the conversion rate of lithium battery and lithium-air are similar. The maximum power can be achieved if the stroke is greater than 1.5mm, even 4540 will do, depending on the application conditions.

When it comes to the length, we have to talk about the material of the battery, so read more papers when you have time.  EB is also called hollow grade, also called, abs resin, abs and sac have a diaphragm, the thinner the diaphragm, the better the effect of the diaphragm. The conversion rate is important because the electrolyte can dilute the battery. This is a bit like a bridge battery, with less self-discharge and less battery loss. It is precisely because the electrolyte of the negative electrode is diluted that the aluminum-lithium battery can easily run out. Working voltage value. In the case of the same nominal weight, the increase in material density will greatly reduce the volume of the material, thereby shortening the stroke of the battery. The thinner the battery, the better, but the capacity is often limited.
