We take on big challenges and enjoy creating new things. The Li-Ion batteries are built with LCO cathodes combined with a graphite anode. Our development focuses are plastic, stacking and micro technology, and we also place a great deal of importance on the materials used, the manufacturing processes and the miniaturisation, Today, we have some technologies in use, that are unique worldwide and open up new possible applications to us.

Today, our patented plastic technology is seen as unique worldwide. We use a gas proof plastic for the casing. The advantages of a plastic casing are clear and just as convincing:

• Many possibilities for shape
• Maximum capacity with miniature batteries / cells (the smaller the battery, the greater the advantage of Wyon technologies)
• Organic compatibility (skin and cerumen friendly)
• Light weight
• No tension on the casing
• Hermetically sealed
• First company worldwide, who only manufactures Li-Ion batteries in plastic casing (without metal casing)

The following example shows how a battery with more energy density is possible from an existing volume thanks to the free choice of shape.

• Optimum adjustment to design or existing volume.
• Higher capacity compared to a button cell battery, because the volume can be optimally used

The potential of plastic technology can only be used with a corresponding stacking technology. Therefore, Wyon has developed a patented and today worldwide unique stacking technology. The advantages are huge, particularly with small and micro sizes:

• High security and reliability due to precise layout of the anodes and cathodes
• Free shaping (curved, triangular, circular etc.)
• High energy density is possible due to the maximum use of the free volume
• Flat battery heights are possible

Apart from chocolate and cheese, Switzerland is also known for competences in micromechanics. Wyon has well-grounded expertise and longstanding experience in this specialist area and can produce rechargeable Li-Ion batteries in micro sizes thanks to this knowledge. The following micro battery was developed for an implant and is intended for a life span of 10 years.

We offer customer specific cells/batteries and standard cells. Technology and innovation define our everyday. Our plastic and stacking technologies are unique worldwide. We are very flexible and can manufacture our products in small and large quantities. With our high quality products, we have been successful in the area of medical technology for many years. We also see potential applications for our technologies and our products, in other areas of application such as industry and entertainment electronics, telecommunications, Internet of Things and others.

Our plastic, stacking and microtechnologies are worldwide unique today. This means that we can develop and produce an optimum cell or battery for the customer, with maximum energy density. We have a multitude of possibilities. The following product overview and development times give an insight into our customer specific range of batteries.

For companies that are looking for high performance cells with quick availability, we now also have a range of standard cells. You can buy these products in small quantities and large quantities (> 1 mil. pcs/year)). You can find the most important information in the following product overview.

Charging Li-Ion batteries is an important factor for their lifespan. Therefore, we offer the customer a charger that matches the battery and the application, if required.

The design of the charger is created according to the customer’s wishes.

The production of the batteries takes place completely in Switzerland. 100% traceability. All batteries are individually checked several times. This means, that each individual battery is checked electrically and visually for predetermined errors. The values for each individual battery collected from this will also be saved in a database and can be traced back.

Our company fulfils the ISO 9001 standard. However, all processes are already designed for ISO 13485. We are consistently striving to perfect the quality even further.

In our development laboratories, we are in a position to carry out all safety related tests on batteries, such as IEC 62133, UN Transport etc. Thanks to these possibilities, the batteries can be tested in accordance with the regulations and also the extended requirements.
