Shelf life lithium manganese dioxide

Although a number of different solid-cathode lithium batteries have been developed and even manufactured, more recently the trend is toward reducing the number of different chemistries that are manufactured. The lithium/manganese dioxide (Li/Mn02) battery was one of the first to be used commercially and is still the most popular system. It is relatively inexpensive, has excellent shelf life, good high-rate and low-temperature performance, and is available in coin and cylindrical cells. The lithium/carbon monofiuoride (LijCFj J battery... 

Increases in the energy density of primary hatteries has tapered off during the past decade as the existing battery systems have matured and the development of new higher energy batteries is limited by the lack of new and/or untried battery materials and chemistries. Nevertheless, advances have been made in other important performance characteristics, such as power density, shelf life and safety. Examples of these recent developments are the high power zinc/alkaline/manganese dioxide batteries for portable consumer electronics, the improvement of the zinc/air battery and the introduction of new lithium batteries. 

SAFT supply this type of battery. The particular advantages claim for lithium-copper oxide batteries are long operating life, long shelf life (up to 10 years projected) and high operating temperature (tested between — 20 and - -50°C). Volumetric capacity (Ah/dm ) is 750 compared with 300 for alkaline manganese dioxide, 400 for mercury-zinc and 500 for lithium—sulphur...
