6. Calculate the rated capacity based on the required working current and working time; Rated capacity=working current× working hours 7. Determine the design capacity; Design capacity=rated capacity * design coefficient...

2. Determine the number of audio cells in the combination battery, as well as the working voltage and current density of individual cells; 3. Determine the total working voltage, working current, and other indicators of the battery pack according to user requirements, select...

These two types of batteries are like twin brothers, and most people are not very clear about them or understand their differences. In fact, for us ordinary consumers, these two types of batteries are not very different, but they have been used for a long time. For example, after using them fo...

3、 The optimization of electrolyte composition and the production process of lithium-ion batteries require electrolyte to maintain capacity and extend battery life: 1. Suppress the reaction between the positive electrode material and the electrolyte, 2. B...

1、 Improving the physicochemical structure of positive and negative active materials is the fundamental link in the production process of lithium-ion batteries: 1. Appropriate ion doping of materials 2. Try to use materials with disordered layered structu...

By the way, it's best not to charge lithium-ion batteries in winter. Due to low temperature, the lithium ions nested on the negative electrode will crystallize and directly penetrate the diaphragm, generally causing micro short circuits that affect lifespan and performance! So some people have r...

The low-temperature performance of lithium-ion batteries made of different materials also varies. Currently, the hottest type of lithium iron phosphate has the worst low-temperature performance. Our product has a capacity of 89% of its maximum capacity at -10 ℃, which should be relatively hig...

The car owner chooses to replace the lithium-ion battery, which costs approximately 1500 yuan. The old battery is worth around 300 yuan, and the cost of replacing it with a new one is around 1200 yuan. Normally, the service life of a lithium-ion battery is 4-5 years, which is 2-3 years longer...

3、 Current, such as the 18650 battery cell discharging at 3C, and your electric vehicle discharging at 8000W. The battery cell used is lower than the discharging current of your electric vehicle, which can cause the temperature of the lithium-ion battery to be too high, the current to be too high,...

There are three important categories of lithium-ion batteries for electric vehicles. The first is ternary lithium, which is also a widely used type of lithium-ion battery. The second is lithium iron phosphate, and the third is lithium titanate. Among them, lithium titanate has a low popularity and i...
