碳素材料用作电池负极材料的现状和前景

Present Situation & prospect of Carbon Material Used as Negative Pole of Cell

锂离子二次电池是当前电池制造的新发展,由于在电极表面难以析出金属锂,是无公害的安全电池,用作电池负极的石墨材料有多种,其中以中间相碳素微球(MCMB)为佳。由于新型的碳素材料的应用大幅度地降低了电池成本,以长远的观点。此类电池能扩大应用为电动车辆的电源,将具有广阔的市场前景。

Lithium ion reusable cell is the new tendency for current cell manufacture. Since its electrode surface hardly separate out metallic Lithium, it is a safe cell without environmentalpollution. There are various kinds of graphite used as cell negative pole, in which MesocarbonMicrobeads (MCMB) is considered the optimal material. The cost of cell is reduced to a largeextent due to the application of novel carbon material. From a long-term point of view, this sortof cell could be further powered to electric vehicles and it would have extensive market prospect.
