REPLACING LEAD ACID
After 150 years of development, lead acid still has a lot of development potential, or so some say. But as it stands now, Li Ion, with three times the energy density and between three and five times the cycle life of a maintenance free, VRLA battery, the only real card Lead Acid has to pay is price. Even this thin advantage is eroding as Li Ion gets cheaper and the life cycle advantage gets taken into account.
The case for lead acid weakens further when low temperatures are involved such as in a cold room, here the energy content of the battery may be as little as 20% of the capacity and room temperature, Li Ion would typically be at least 70%.
BATTERIES IN MORE DETAIL
Li Ion batteries represent a family of chemistries typically relating to the cathode chemistry and in the case of Titanates, the anode. The different chemistries have different characteristics and costs that make them suitable for different applications.
For industrial applications, FePO4 is the favoured for cost and safety reasons, as it is not susceptible to thermal runaway and does not include expensive cobalt as part of its cathode. Hardcase, prismatic, large format batteries with costs of around €0.50/Wh are now readily available. When combined with a suitable battery management system, these batteries are already capable of competing favourably with Lead Acid when viewed on a lifetime costs basis.
Offering motive power batteries in 12V, 24V, 36V, 48V, 60V, 80V, 96V and other custom voltage applications.
