Soft carbon, also known as easily graphitized carbon, refers to amorphous carbon that can be graphitized above 2000 ℃, with low crystallinity, small grain size, large spacing between crystal planes, and good compatibility with electrolyte. However, the irreversible capacity of the first charge and discharge is high, and the output voltage is low. Due to its performance, it is generally not directly used as a negative electrode material and is a raw material for manufacturing natural graphite, such as petroleum coke and needle coke.
Hard carbon, which is also difficult to graphitize, is a pyrolytic carbon of polymer materials. This type of carbon is also difficult to graphitize at high temperatures of 3000 ℃. Hard carbon includes resin carbon (such as phenolic resin, epoxy resin, polyfuryl alcohol, etc.), organic polymer pyrolysis carbon (PVA, PVC, PVDF, PAN, etc.), and carbon black (acetylene black); It is beneficial for the insertion of lithium without causing significant structural expansion, and has excellent charge discharge cycling performance.
The capacity of hard carbon is greater than the theoretical capacity of conventional carbon materials, with excellent high magnification, cycling performance, and safety performance. However, the initial efficiency is low, about 85%. The voltage platform of 3.6V is lower than that of 3.7V of graphite, and the cost is high. The main improvement ideas are to improve the first effect (reducing the specific surface area to form a more regular hard carbon; surface coating to control SEI formation); Improve material yield and reduce costs.
