Guide: Mobile phones are becoming more and more important in our life. It brings us a lot of convenience and adds a lot of fun to our life. As we all know, batteries are a very important part of mobile phones. Mobile phones need batteries to run, but there will be some problems after the batte...

Although the charging cost of electric vehicles is relatively low compared with traditional fuel vehicles, due to the high price of electric vehicles and the relatively short service life of batteries, the replacement of batteries will also be a huge expense, so the cost barrier 'battery mainten...

With the commercialization of lithium batteries becoming more and more widespread, the charging and discharging process of lithium batteries on the surface of the positive material is that when the battery discharges, the lithium ions in the hole enter the positive active material. If the current in...

Lithium battery refers to the battery containing lithium (including metal lithium, lithium alloy, lithium ion and lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries a...

Lithium battery has many advantages, such as high energy density, stronger discharge capacity than dry battery and nickel-cadmium nickel-hydrogen battery, faster charging speed than nickel-cadmium nickel-hydrogen battery, and no memory effect of nickel-cadmium battery. Waste dry battery and nickel-c...

The ideal polymer gas separation membrane material should have high permeability and good permeability selectivity, high mechanical strength, excellent thermal and chemical stability and excellent film-forming processing performance. Among the above requirements, the gas permeability of the ga...

Lithium iron phosphate battery refers to lithium ion battery with lithium iron phosphate as cathode material. The cathode materials of lithium-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc....

1. 2 for startup, 3 for power, 4 for fixed valve control and sealing, and 4 for small valve control and sealing. This method is mainly classified in terms of structure, but also in terms of use. It is still difficult for non-battery practitioners to understand. It is easy to understand from the pers...

Lithium ion battery manufacturers talk about graphene lithium ion battery large modulus output can not be achieved? It is understood that the single-layer rate of products produced by the ten-ton production line of spinning grade single-layer graphene oxide is more than 99%, which can support...

How far is lithium-ion battery as the "group pet" of energy storage project? As an emerging field, lithium-ion battery energy storage has developed rapidly around the world in recent years. At present, there are three important applications in the energy storage lithium-ion battery market:...
