Special graphite for green non-mercury battery has been in production after ultra-low molybdenum high purity graphite came into production. It possesses the features of high purity (99.9%-99.99%), good electric conductivity, and low content of trace elements. The stable technical properties ensure that it can greatly improve the living life of battery, and also be an important raw material of green protective non-mercury alkaline battery.
