The lithium ion battery conductive paste is mainly a carbon-based conductive paste, and includes conductive carbon black, conductive graphite, carbon nanotubes, graphene and mixed slurry thereof Generally, carbon black and graphite are referred to as conventional conductive pastes, and carbon nanotubes, graphenes and mixed pastes thereof are referred to as novel conductive pastes.

A research team at Purdue University published a study on the relationship between the activity and inactive elements of lithium-ion batteries and how the micro and nanostructures of their respective components reflect the performance and safety of the battery The study was recently published on the cover of ACS Applied Materials & Interfaces magazine.

There are usually two types of exteriors for lithium batteries: cylindrical and rectangular The inside of the battery adopts a spiral wound structure, and is formed by spacing a positive and negative electrode with a very fine and highly permeable polyethylene film insulation material.

The reason for low capacity can be divided into two directions of design and process This article first talks about the design, and then the next part of the process.

Today, most electronic devices such as smart phones, tablets, wearable devices and electric vehicles use rechargeable lithium-ion batteries However, these lithium batteries service for two to three years, function and efficiency will be degraded and even died.

I don't know for the majority of office workers What is the most troublesome thing? I think that traffic jam must be one of them.

When the capacity of the negative electrode is insufficient, or there is no capacity at all, part or all of the lithium generated during charging cannot be inserted into the interlayer structure of the negative electrode graphite and it is deposited on the surface of the negative electrode to form a protrusion And this protrusion is more likely to cause lithium to precipitate during the next charge.

One of the important performance indicators of battery performance is the battery capacity, which indicates the amount of electricity discharged by the battery under certain conditions (discharge rate, temperature, termination voltage, etc) (Discharge test can be performed with JS-150D), that is, the capacity of the battery, usually in amps.

According to a report completed by the International Copper Association (ICA), the rapid development of electric vehicles in the next 10 years will drive demand for copper The report, "Copper Intensity in the Electrification of Transport and the Integration of Energy Storage," jointly completed by ICA and IDTechEx, analyzes the prospects for copper consumption in electric vehicles.

China National Nuclear Power's total investment of 830 million yuan of 300 million ampere-hour lithium battery project settled in Chibi City The project will be constructed in two phases, with a phase of 120 million yuan and a phase 710 million yuan.
