energy storageEnergy storage lifePo4 batteries (lithium iron phosphate) began to dominate more discerning designers and customers. These cells in electric vehicles has been using since 2011, and now appears in the fixed-power applications.

LiFePO4 battery expected life cycle of the daily off-grid system is 13-15 years old, and no less than 20 years of backup means occasionally bike. Life (EOL) End cell is defined by the 70% of them contain life (BOL) capacity early. However, with the passage of time it is linear capacity deterioration (deterioration does not become substantially more rapid and prolonged use), and thus can be used in cells longer if lower scrap capacity is acceptable.

Higher initial cost compared to LiFePO4 systems lead batteries installed by sharp throughout the life cycle cost savings, since the cost per kilowatt-hour calculation of compensation during its life fed by the battery pack. Even if not in lead crystal battery life cycle cost competition. 30% of the lifetime cost per kilowatt hour down to a typical lead-acid deep cycle battery costs.

The main reason for this situation is that the number of cells with up to ten times more than the general period of deep cycle lead-acid batteries and up to five times more powerful single cell type. This is the case of a large current discharge and charge of the scene is particularly evident by the high ambient temperatures, neither of which is suitable for lead batteries for further comparison.
