Positive grid plate single cells in gel-design for telecommunication application

摘要

In the Telecommunication Application there is a tendency to reduce the Backup-Times from mainly 3 to 8 hours down to 30 minutes to 1 hour. To fulfill the requirement for long lasting batteries in this application field the battery must be at least a ten years system with the ability to supply high currents on short term discharges. The combination: Service Life ＞ 10 years and High Rate Discharge 50% of C10 at the one hour rate requires a new design of a telecommunication battery. The system described in this paper fulfill the above mentioned requirements and applies also construction features and manufacturing experiences which are well approved in the telecommunication application.
