About Photovoltaic Energy StorageThe discharge test for 10 C (23 A) went well with a recorded cell temperature rise of 49°C. Once the cell voltage reduced to 4 V (measured under load), the battery provided a mean discharge voltage (Um) of 5.68 V or 2.84 V on each cell. The energy density was computed to be 94 Wh/kg.
About Photovoltaic Energy StorageIn spite of the splendid features, nickel-iron alkaline batteries have been substituted by emerging batteries such as Ni-MH batteries, Ni–Cd batteries, lead-acid batteries, and Li-ion batteries. This is primarily attributed to the high self-discharge rate, poor energy density, and the low Coulombic efficiency of iron anode [ 50, 83 ].

About Photovoltaic Energy StorageIn contrast, invented and commercialised in the early 20th century, nickel–iron (NiFe) cells could provide 1.5–2 times the specific energy of lead/acid batteries, with their increased ruggedness and longer cycle life at deep discharge state (2000 cycles at 80% Depth of Discharge) [8, 11, 13, 16, 17].
About Photovoltaic Energy Storage5. Self-Discharge Self-discharge is the loss of charge in a battery over time. The rate of self-discharge varies depending on the chemistry and temperature of the battery. Higher temperatures cause an increased rate of self-discharge, while colder temperatures slow it. Lithium iron phosphate batteries have a very low self-discharge …
