Graphite materials include high purity, high strength, high density, medium coarseness, etc., but there is also a possibility that few people have heard of it, because there is a kind of isostatic pressure graphite in graphite materials. Isostatic pressure graphite is a new type of graphite material developed in the 1940s and has a series of excellent properties. Isostatic pressing graphite has good heat resistance. In an inert atmosphere, its mechanical strength increases with the increase of temperature, reaching * value at about 2500 ℃; Compared with ordinary graphite, the structure is fine and dense, and the uniformity is good; The thermal expansion coefficient is very low and has excellent thermal shock resistance; Isotropy, strong chemical corrosion resistance, good thermal and electrical conductivity; It has excellent machinability.

thereforeGraphite saggerIt is a new special material for the production of high-energy density primary batteries. It is the best material with high energy density, high stability and high utilization rate obtained by the battery industry so far.

So far, graphite sagger is an ideal anode material. The molecular formula of graphite sagger is (CFX), (0.5 & lt; X & lt; 1). X> 0.5 graphite sagger can ensure energy density in the range of 800 ~ 860a / m2. When the x value increases from 0.62 to 1, the discharge potential gradually decreases, and the quasi discharge amount and stability are obviously improved. Therefore, when synthesizing fluorinated core ink for batteries, attention should be paid to the control and selection of conditions.

The conversion of active material fluorine on the anode is the basic reaction of battery discharge. From the electrochemical characteristic reaction formula, it can be seen that the graphite sagger has good discharge characteristics. The main reason may be due to the rapid transfer of fluorine in the graphite plate lattice, which converts (CF) into monomer activated carbon. This kind of carbon has improved electrical conductivity during discharge, which provides conditions for high-speed and smooth discharge.

Discharge characteristic curves of several anode active materials such as graphite sagger (CF), copper fluoride (CUF:), silver chloride (AGA). As can be seen from the curve:Graphite saggerIt has good and stable discharge characteristics, and the voltage drop is almost zero, that is, the discharge efficiency is high, close to 100%. When silver chloride and copper fluoride discharge, the voltage drop is large, and the discharge efficiency is not high. The specific graphite sagger inspection standards are as follows:
