As the electric vehicle market continues to expand, battery technology, as its core component, has received widespread attention. Lithium iron phosphate and ternary lithium batteries are currently the two most commonly used battery types in electric vehicles. Each of them has its own unique advantages and applicable scenarios. Below we will discuss their differences and […]
Hard carbon will not graphitize after high-temperature treatment. Its internal crystal arrangement is disordered, and the layer spacing is large. This makes the hard carbon anode store more charge in the same volume. It improves the energy density and endurance of sodium-ion batteries. The expansion and contraction of the hard carbon anode are more uniform

The mainstream process from coke to graphite is divided into four major steps and several smaller steps. The four major steps are crushing-granulation-graphitization-screening and demagnetization. Among the four major processes of artificial graphite, crushing and screening are relatively simple, while granulation and graphitization are more complex. High-end artificial graphite requires more processes, such as secondary

Hard carbon refers to difficult-graphitizable carbon, which is a kind of pyrolytic carbon obtained by pyrolyzing high molecular polymers, petrochemical products, biomass, etc. Due to the presence of a large number of H, O, N and other heteroatoms in the precursor, the formation of crystalline regions during heat treatment is hindered, making it difficult to

Advanced ceramic raw materials, electronic ceramic raw materials, photovoltaic cell materials, quartz minerals and other medium and high hardness mineral materials have high hardness, high anti-pollution requirements, high powder fineness, and concentrated particle size distribution, which is a major problem in the grinding and classification process.Dry and wet methods are the two most common and
After years of development, the energy density of lithium-ion batteries has been greatly improved. Statistics show that the energy density of lithium-ion batteries increased three times from 1991 to 2015, with a GAGR (annual compound growth rate) of about 3%. However, from the perspective of actual technological development, the current growth rate of lithium-ion battery

Graphite has become the mainstream lithium battery negative electrode material in the market due to its advantages such as high electronic conductivity, large lithium ion diffusion coefficient, small volume change before and after layered structure, high lithium insertion capacity and low lithium insertion potential. As the demand for lithium-ion batteries continues to grow, a large
