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...

Intelligent chargers can provide different charging modes and corresponding algorithms based on the characteristics of each type of battery to achieve good charging results. Rechargeable batteries have high cost performance, large discharge current, and long lifespan, and are widely used in va...

Pulse charging mainly consists of three stages: pre charging, constant current charging, and pulse charging. Compared with conventional charging methods, pulse charging can charge at a higher current. During the shutdown period, the concentration polarization and ohmic polarization of the batt...

Electrolyte - A mixed solvent system consisting of LiPF6 ethylene carbonate, propylene carbonate, and low viscosity diethyl carbonate alkyl carbonates. Diaphragm - uses polyolefin microporous membranes such as PE, PP or their composite membranes, especially PP/PE/PP three-la...

Structural composition of lithium-ion batteries Lithium ion batteries are alternative products to metal lithium batteries that emerged in previous years. The important components of batteries are positive and negative electrodes, electrolytes, separators, and shells....
