TechnologyOur technology
The advanced technology we have cultivated enables us to create high-performance materials which meet and exceed the expectations of each and every customer.
Even if batteries are produced for the same application, there are many differences in battery design among manufacturers and products. Depending on these differences in design the optimal materials for each battery will vary, for example, depending on how and to what degree the battery materials are mixed at the atomic level. Therefore, as a battery material manufacturer, we are required to accurately and quickly recognize the performance and features required for cathode materials in accordance with each manufacturer's design. We use the diverse knowledge and technologies we have nurtured through our extensive experience to provide high-performance battery materials that meet and exceed the expectations of our customers.
Strong Point Tanaka Chemical Corporation Technology・Strengths and Features
A deep of knowledge of the “reaction process,” the cornerstone of our production.
The reaction process that is always required to manufacture any cathode material or precursor is central to our production. In this process, an alkaline solution such as sodium hydroxide is added to a solution of raw materials which have been dissolved in acid. Over our long history as a battery materials manufacturer, we have acquired a deep and varied knowledge concerning this reaction process. This knowledge and experience is utilized in all of our product development and production, enabling us to control the temperature and agitation of the reaction solution during the neutralization reaction to ensure optimal manufacturing methods. In addition to our knowledge at the laboratory level, we also have extensive expertise in mass production at the manufacturing level, enabling us to minimize quality variations during mass production.
Four core technologies that control the crystal structure at the molecular level.
Cathode materials and precursors are, broadly speaking, metallic compounds. The properties of these metallic compounds vary greatly depending on their crystal structure and shape. Therefore, in order to manufacture cathode materials and precursors that deliver the expected performance, it is necessary to be focused on the crystal structure at the atomic level and the particle shape at the nano- to micron-level, and to proceed with production under appropriate control. Tanaka Chemical Corporation manufactures products while controlling chemical reactions at the atomic level by making full use of a variety of proprietary technologies and expertise, centering on four core technologies, including "particle sphering technology," which we have established over the course of our history.
