Targray has partnered with Osaka Gas Chemical to offer new graphite anode active materials. For the past 100 years, Osaka Gas has a long history of making anode materials - as they were the first company to introduce MCMB. In collaboration with Osaka Gas, Targray can offer a series of Graphite anode active materials to battery manufacturers.

Gramax

Since 2002, Osaka Gas has been involved in researching and developing Gramax – a Japanese, high-quality, competitively cost Artificial Graphite. Since 2011, Osaka supplies customized Gramax materials on a mass produced scale.

Gramax Key Features & Benefits:

• Coke-derived material
• Heat treated with moderate temperature (2000-2500 C)
• Almost graphite but some turbostratic structure
• High power
• High reliability (cycle c/d, float charging and high temperature storage)

OMAC-R is also available. It is a surface treated Natural Graphite, with extremely low costs.

Graphene

Using a composite of graphene and metal oxides, Targray has partnered with Vorbeck Materials to offer a novel anode active material called Vor-Charge, for High Current and High Energy applications bringing you ultra-high performance.

Graphene Key Features & Typical Benefits:

• Vor-charge High Current (HC): High Current, Short recharge, Extended life, good temperature range
• Vor-charge High Energy (HE): High energy storage capacity, Short recharge, good cycle life
