On the basis of super low mesh high purity graphite, Tianhe has recently developed and manufactured new graphite specially for green mercury-free battery, which is of high purity, excellent electricity property, and super low trace element. Alltypes of trace elements in graphite are strictly controlled by taking advanced chemical production technique. Thank to its stable technical performance, the special high purity graphite can be used as a replacement for imported one, and can greatly improve the usage length and storage life. it is also an important raw material for green and ecological mercury-free alkali battery.
T-399.9
high temperature resistance,good heat and electricity conductivity,strong chemical stability,acid and alkali resistance,toxic free and harmless,excellent green and ecological material.
mainly applied to green mercury-free alkali battery,secondary battery,lithiumion battery,inside and outside coating of radio tube etc.
