Major components and working principle of a Li-ion battery. Despite the exploration of many kinds of cathodes, anodes, separators, and electrolytes, the basic working principle of a LIB remains almost the same as it was decades ago. Electrodes are connected to an external source of energy during charging.
Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
In addition, the Li-ion battery also needs excellent cycle reversibility, ion transfer rates, conductivity, electrical output, and a long-life span. 71, 72 This section summarizes the types of electrode materials, electrolytes, and separators that have been developed and optimized to produce high-performance Li-ion batteries.
Based on the previous study, in this research a new cell-to-cell balancing circuit for lithium-ion battery strings is proposed to overcome the drawbacks of the conventional cell balancing methods. In the proposed topology, the charge is transferred from a high-voltage cell to a low-voltage cell directly by using a push-pull converter.
