Battery separator technology – an important role in the next generation of electric vehicles

The NSG Group is a world leader in the development of advanced glass products for use in battery separators. These are sheets of non-conducting porous material between positive and negative plates in storage batteries. They prevent short circuits caused by plates bending and touching and greatly increase the efficiency of batteries.

Initiatives to achieve a low-carbon society have focused the automotive industry on the development of more fuel-efficient vehicles. The Idling Stop and Start (ISS) system, which stops the engine during idle time and restarts only when necessary, requires advanced performance batteries.

Our R&D is focused on improving the capacity, stability, power and safety margins of the next generation of batteries. Enhanced performance characteristics can enable the use of smaller and more powerful batteries in future lower emission vehicles. Our sales of separators for these new batteries are expanding rapidly.

We are developing and expanding sales of separators for smaller and more powerful batteries for use in
future lower-emission vehicles.

Displays in communications devices — helping to cut power consumption and even reduce travel

We are a world-leading supplier of ultra-thin glass for small LCD applications, helping to reduce power consumption in the display market. Our Ultra Fine Flat Glass (UFF) is produced in thicknesses as low as 0.3 to 1.1mm.

These products are increasingly being used in the growing touch panel market, particularly in mobile phones and computers (including new tablet models) and now expanding into use in vehicles.

This technology helps reduce the need for additional peripheral equipment, such as keyboards and pointers, saving manufacturing resources, raw materials and energy. Mobile communications devices also help reduce the need for face to face interaction and travel.

Our new range of advanced LED print heads offers the advantages of miniaturization, reduced noise and lower power consumption in the next generation of printers and scanners.

LED print heads — reducing power consumption in office machinery

We have been involved with printer and scanner manufacturer Fuji Xerox in the joint development of a new generation of Light Emitting Diode (LED) print heads, using our proprietary SELFOC® Lens Array (SLA®) technology, which allows optical systems to be designed compactly and manufactured at low cost.

The new system uses self-scanning light-emitting devices and radially distributive refractive index rod lens arrays to provide images up to 1,200 dpi. The new print head provides an image quality equal to or surpassing more conventional laser scanning units, but with the added advantages of miniaturization, low power consumption and low-noise operation.

Glass cord engine timing belts — helping to reduce fuel consumption

Glass and Climate Change_TechGlass

In the automotive industry, timing belts play a crucial role in maintaining optimal engine performance and fuel efficiency. Our advanced glass cord is used in a new generation of belts. NSG Glasscord®, high-tensile strength glass fiber cord, improves belt flexibility and stretch-resistance significantly. These characteristics help to provide accurate valve operation timing, for better fuel efficiency over the lifetime of an engine.

The technology has been advanced with the development of the new ‘Belt in Oil’ system using NSG Glasscord®. The system improves engine refinement further, through an innovative design that immerses the two main engine drive belts in oil. The system delivers the quietness and more efficient running of a belt, but with the durability of a chain.

Unveiled at the 2011 Frankfurt Motor Show, Ford’s revolutionary
new EcoBoost™ engine features the NSG Glasscord® ‘Belt in Oil’
timing belt system, developed by the Group’s NGF EUROPE subsidiary, part of the Specialty Glass business.

The use of glass fiber cord in the Belt in Oil system improves belt
flexibility and stretch resistance significantly. The new system offers the quietness and low friction running of a belt, combined with the durability of a conventional chain system.

Glass sound insulation — reducing noise pollution

Increasing traffic levels alongside built-up areas have boosted demand for acoustic screening to enhance the quality of life of the local inhabitants. Our Nippon Sheet Glass Environment Amenity (NEA) operation supplies the market for sound insulation systems for industrial use, acoustic architecture, expressways and residences, as well as electromagnetic wave shielding systems.

Although transparent plastics, such as polycarbonates and acrylics, are also used for soundproof panels around expressways, glass offers significant advantages in terms of aesthetics, durability and cost.
