BPP key material spherical graphite anode material for lithium battery

Product Description

Natural and synthetic graphite are used to construct the anode of all major battery technologies. The lithium-ion battery utilizes roughly twice the amount of graphite than lithium carbonate. The demand for batteries, primarily nickel-metal-hydride and lithium-ion batteries, has caused a growth in graphite demand in the late 1980s and early 1990s.
Graphite powders are used as additives in the cathode cell alkaline batteries. The high degree of crystallinity of the graphite powder provides the necessary electrical conductivity of the cathode mass, increases the mechanical strength of the electrolyte, and optimizes absorption. Moreover, the lubricating effect of the graphite minimizes the wear of the tool elements in the production of alkaline batteries.
Nowdays, most anode material for Li-ion batteries are made from graphite. It plays a vital role in modern Li-ion battery industry.
Inside fuel cells, the bipolar plates (BPP) are a key component in chemical generators, and other power systems electrical fuel elements in electrochemical reactions. BPP typically includes carbon composition in the form of expanded graphite (which in turn is produced from natural flake graphite).

Spherical graphite is made by micronizing, rounding, and purifying flake graphite. This increases the surface area and conductivity which creates an enhanced battery anode product. The round shape also results in a higher density in the battery, better capacity and longer life.

Due to its unique characterization, each end user requires spherical graphite with different specs, which can best fit their processing method and equipment. Therefore, we don’t have standard grades; instead, we work with our customers to develop the grades that most fit them.
