The study of SOH in lithium-ion batteries involves internal state variables such as internal temperature, electrolyte concentration, and internal resistance in electrochemical models. However, accurate monitoring of the internal state of batteries is very difficult, and quantitative analysis o...

The research on the health status and lifespan of lithium-ion batteries is receiving increasing attention, but the research on battery SOH is still in its early stages, which is important for the following three reasons. 1. Long research cycle and strict control of experimen...

(2) Blade battery charging speed is fast In terms of charging speed, Han can charge the remaining 8% of the battery to 80% within 25 minutes; Under comprehensive operating conditions, charge for 10 minutes and have a range of 135 kilometers. Generally spea...

Make the volume energy density of the lithium iron phosphate blade battery close to that of the currently produced 811 ternary battery with the highest individual energy density. That is to say, consumers can spend the price of purchasing vehicles with lithium iron phosphate...

2、 The driving range can reach 600 kilometers In addition to safety, there is also driving range. The common understanding among people about lithium iron phosphate batteries is that they have outstanding safety, but unfortunately, their volumetric energy...

That is to say, when new energy vehicles are invaded by foreign objects and damage the battery, BYD blade batteries will not explode, which can effectively protect the safety of personnel inside the vehicle. (2) Ceramic battery technology, further improving safety...

1、 Comprehensive battery safety It can be said that in order to achieve safety, BYD has carried out comprehensive construction from materials to battery cells to battery packs. (1) The characteristics of electrode materials are safe In...

(4) During the recycling process of lithium-ion batteries, due to the low lithium storage capacity of the negative electrode material or the rapid release of lithium ions from the positive electrode, too many lithium ions are released on the surface of the negative electrode, and over time, dendriti...

The causes of short circuits in lithium-ion batteries (1) The positive electrode material is impure or left in the air for too long, resulting in incomplete drying; Failure to remove transition metal impurities from the positive electrode slurry can lead to penetration of th...

1. Do not contact the positive and negative poles of lithium-ion batteries with metal objects during use, and keep them away from metal objects and places with high temperatures to avoid short circuits in lithium-ion batteries. 2. When not in use for a long time, lithium-ion...
