Renata Lithium-Polymer-LösungenTechnology and Design

Nickel contacts of the battery enable soldering and welding processes to connect the cell during end product manufacturing process. A high temperature resistant shut down separator is implemented since safety comes first. To achieve a constant capacity over the discharge cycles Renata uses high accuracy in production of the positive and negative terminals. Furthermore, the laminated film case will avoid water diffusion out of the battery which result in very long shelf life and over 800 charge/discharge cycles.

Quality and Preconditioning

Another important topic is that there is no critical point related to bulging effects. After production Renata gives the battery a special treatment: The battery will be 100% charged, 100% discharged, degassed and 30% charged before it will be shipped out. By this Renata guarantee high quality and low deviation across production lots. This free the customers from doing all these pre-treatments on their side.

All products (table overview) will be delivered by air transportation to avoid uncontrolled conditions during sea freight shipments. In addition to the necessary certifications like UN 38.3, most batteries are already additionally certified according to IEC62133 to meet today's safety requirements in the industry.
