Understanding the underlying mechanisms of the charge–discharge behaviour of batteries, especially Li-ion and Na-ion intercalation ones, is obligatory to develop and design energy storage devices. The behaviour of the voltage–capacity/time (V – C / T) diagram is one of the most critical issues which should be understood.
Constant-current charging entails sending a constant current to the battery during the charging process. The charging rate remains constant as the battery voltage increases. When the battery voltage is low, this method is frequently utilized in the early stages of charging. ii.
Battery manufacturing and chemical properties may fluctuate when discharging and charging. Passive and active cell balancing mechanisms were proposed. Impedance, electrochemical problems, concentration polarization, and energy scattering in development are the main causes. Li-ion cell hysteresis measurement improves precision despite its influence.
Beyond the LIB challenges, it is critical to consider that several applications ideally require different types of rechargeable batteries. Therefore, LIBs alone cannot be ideal for various applications, despite their high performance. Hence, the increased need to develop other types of batteries for energy storage.
Although battery energy storage accounts for only 1% of total energy storage, lithium-ion batteries account for 78% of the world’s battery energy storage system as of 2021 . Lauded for their high energy density, lithium-ion batteries dominate the battery market. The field of lithium-based batteries is continually developing.
In evaluating the sustainability of beyond-lithium technologies, beyond the criticality of the raw materials used, the whole battery’s life must be considered. This ranges from the extraction of raw materials and battery manufacturing to its daily operation and recycling.
