Showa Denko K.K. (SDK) Starts Volume Production of LIB Anode Binder

Tokyo, Feb 26, 2013 - (JCN Newswire) - Showa Denko K.K. (SDK) has started volume production of "Polysol(TM) LB Series" water-based anode binder for lithium ion batteries (LIBs) at its Tatsuno Plant in Tatsuno City, Hyogo Prefecture.

The product is a water-based emulsion containing acrylic synthetic resin particles, ensuring lower environmental impact at the time of production compared with solvent-based binders. It provides such advantages as low electrical resistance, good temperature characteristics, and good adhesion to anode collectors, thereby contributing toward extending the life and increasing the capacity of LIBs. Having improved the product properties based on the results of sample evaluation by potential customers, SDK has decided to sell the product on a commercial scale.

Development of LIB technology is being accelerated. This is because small LIBs for high-performance smartphones and tablets need to become thinner and have higher capacity. Also, large LIBs for industrial/home storage batteries, electric vehicles and hybrid cars should have high capacity, long life, and good durability under severe working conditions.

In addition to the four major LIB components (cathode material, anode material, separator, and electrolyte), binders are a target of technological development as they significantly influence the performance of LIBs.

A binder causes cathode/anode active materials (for release and intake of lithium ions) to stick together. It also causes additives to stick together, and active materials to adhere to collectors. While styrene-butadiene rubber (SBR) is mainly used in binders, it has a problem of deterioration at high/low temperatures.

Compared with SBR, "Polysol(TM) LB Series" can improve temperature characteristics by around 10%, in terms of the maintenance of capacity at the time of charge/discharge after preservation at a high temperature (60 degrees C) and in service capacity at a low temperature (-20 degrees C).

Furthermore, it exhibits high binding property with addition of a small amount due to its high dispersibility, and increases adhesion to anode collectors (made of copper) by 1.5 times, enabling reductions in inner electrical resistance. Thus, "Polysol(TM) LB Series" will contribute toward extending the life and increasing the capacity of LIBs.

The Showa Denko Group will continue to fully utilize its proprietary inorganic, aluminum and organic chemical technologies to improve the performance of its LIB-related products, including anode material, additive in anodes/cathodes, packaging material, and binder. At the same time, the Group will provide total solutions to customers, making proposals on ways of combining various components to better meet their requirements.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
