If too much is transferred, the structural framework of lithium cobalt oxide will collapse, so lithium cobalt oxide can only be charged to 4.2V And the ternary voltage can be charged up a bit, such as 4.25V, 4.3V, and 4.35V. But no one charged to 4.4V It i...

Lithium cobalt oxide is a material that is prone to structural collapse after more than half of the lithium is removed, The theoretical specific capacity is 2754.2V, which is generally between 140 and 145. Someone has done lithium cobalt oxide before, and the capacity is about 155-160mAh/g at...

Last protection The final protective wall will be established at the software system level. The new energy vehicle power battery management system (BMS) will provide high-voltage electric shock protection, vehicle collision and power outage protection, high-voltage component...

This is not yet up to standard. In addition to strict waterproof testing, there is also a shy test - 'naked testing'. Ensure that, without relying on any protective measures, the battery cell itself must also have strong pressure resistance, such a...

We just need to remember the numbers. The IP67 standard is already the highest standard for most civilian grade products. This standard is applied to phones, watches, and other mobile devices that we cannot do without in our daily lives. This set of standards will be aimed a...

New energy vehicles are piling up, some are worried about their range, some are saying that charging stations are not enough. While these concerns are gradually being resolved, others are asking whether these electric vehicles will be afraid of water. As we all know, a mobil...

Plan and integrate lithium ore resources to promote orderly mining and rational allocation. One is to implement unified planning for lithium mineral resources, coordinate mineral rights and equity relationships from a global perspective, and strengthen resource integration efforts. The second is to...

The chaos in the lithium battery market is emerging, and integration is imperative At the same time, the construction of lithium battery standards is lagging behind, and safety accidents are frequent. China has a total of 16 lithium battery standards in fields such as electronics, c...

China is an important producer and consumer of lithium batteries, with the output value of lithium batteries accounting for approximately 30% of the global market. In the first half of 2014, China's lithium battery production approached 2.2 billion units, with an import and export surplus...

Example of lithium battery fire prevention plan This plan draws on advanced foreign experience and is simple and easy to implement. The main components of the fireproof materials used are granular minerals, which are non combustible, non conductive, non corrosive, safe and envir...
