Mel mention these batteries today ( not sure if its was this manufacturer)
A good read if you follow the link at the bottom
The calcium and antimony electrodes in Ambri cells are less than one third the cost of the lithium, nickel, manganese and cobalt in the most common lithium-ion cells. Ambri cells are projected to be priced at less than lithium-ion cells for commercial deliveries starting in 2022. Lowest system capital costAmbri-based systems do not need cooling, fire suppression or module and rack based battery management system equipment, as lithium-ion systems require. Due to minimal degradation, Ambri cells do not require additional energy capacity at the beginning of life or a mid-life augmentation in order to achieve 20 years of operating life. For these reasons, Ambri-based systems are projected to cost 30% – 50% below equivalent lithium-ion systems from 2022 – 2030 even after accounting for the aggressive cell price reductions that are forecast for the incumbent product.Low operating costAmbri-based systems operate without the auxiliary electricity cost for cooling which is an enormous advantage in hot environments where most solar-plus-storage installations are located.
