Sulfur-infused carbon for secondary battery materials
A reactor for producing a sulfur-infused carbonaceous material as a cathode material for use in a Li—S battery is described, including a reactor body capable of withstanding a pressure from about 1 atm to about 150 atm; and an inner sulfur-resistant layer at the inner surface of the reactor, wherein the inner layer is inert to sulfur vapor at a temperature from about 450° C. to about 1000° C.
1. A reactor for producing a sulfur-infused carbonaceous material as a cathode material for use in a Li—S battery, comprising:
a reactor body configured to withstand a pressure from about 1 atm to about 150 atm; and
an inner sulfur-resistant layer at the inner surface of the reactor body, wherein the inner layer is inert to sulfur vapor at a temperature from about 450° C. to about 1000° C., wherein the reactor body and the inner layer are made of the same material selected from the group consisting of titanium, molybdenum, Tungsten and a combination thereof.
2. The reactor of claim 1 , wherein the inner layer is a sheath or liner configured to slide in and out of the reactor body.
3. The reactor of claim 1 , wherein the inner layer is a coating coated on the inner surface of the reactor body.
