New energy vehicles are not equipped with fuel engines, so how do they achieve vacuum-assisted braking during braking? New energy vehicles mainly achieve brake assist through two methods:
Th...
Silicon nitride (SiC) is quartz sand, calcined petroleum coke (or coal coking), wood slag (the production of green silicon nitride need to add salt) and other raw materials, through the electric he...
[The energy density of lithium batteries in the future may reach 1.5 times to 2 times the current, which means that the batteries will become smaller. ]
[Lithium-ion battery cost reduction range is...
Silicon carbide fiber and carbon fiber are both ceramic fiber with high strength and high modulus. Compared with carbon fiber, silicon carbide fiber core has the following advantages:
1. Hig...
Atmospheric pressure sintered silicon carbide is no longer just used as an abrasive, but more as a new material, and is widely used in high-tech products, such as ceramics made of silicon carbide m...
A fuel cell system uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat. F...
