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:...

Electric vehicle batteries are divided into two categories: battery and fuel cell. The battery is applicable to pure electric vehicles, including lead-acid battery, nickel-metal hydride battery, sodium-sulfur battery, secondary lithium battery and air battery. Fuel cells are...

The mercury discarded in the natural battery will slowly overflow from the battery, enter the soil or water source, and then enter the human body through crops, damaging human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury and gathered in the body...

With the rapid increase of domestic new energy vehicle sales, the recovery and reuse of new energy vehicle power battery has also been put on the agenda. "Generally speaking, the capacity of the power battery is less than 80% and it can no longer be used in new energy v...

The more the lithium battery is discharged, the greater the loss of the battery will be. "Tom Hartley, a professor of electronic engineering at Akron University who helped NASA study the extension of the battery life, said," The more fully the battery is charged, the greater the loss of th...
