ABSTRACT

The ever-growing production of consumer electronic devices such as mobile phones, laptops, and electronic toys demands energy, and this demand is continually growing, partly because of huge consumer demand and for electric hybrid vehicles, which need a significant amount of energy for their operation (Figure 8.1). Lithium-ion batteries (LIBs) have high energy density, low self-discharge, and no memory effect and are considered as dominant power source that has the potential to meet the necessary current/future requirements (Figure 8.2). In LIBs, during discharge, the Li+ ions deintercalate from the anode (negative electrode) and move toward the cathode (positive electrode) through a nonaqueous electrolyte while electrons flow from anode to cathode in the external circuit, and the whole process gets reversed during charging. 147The efficient operation of the LIBs strongly depends on the different components (electrodes and electrolytes) and any minor discrepancy of any single component affects the performance of the device.
