Final answer:
Lithium-based batteries are favored for high-performance electronics due to their lightweight nature, high energy density, higher voltage output, rechargeability, and their ability to maintain a steady voltage during discharge.
Step-by-step explanation:
Most modern high-performance electronic devices employ lithium-based batteries due to several advantageous attributes. These batteries offer a high energy density, leading to their lightweight nature that is ideal for portable devices.
The ability of lithium-ion batteries to be rechargeable provides significant economic and environmental benefits, as they can be used repeatedly, reducing manufacturing and disposal costs.
Lithium-ion batteries also offer a higher voltage of around 3.7 V when compared with other types, which means more power can be provided by a smaller battery.
Devices that require high energy, such as portable computers and electric vehicles, benefit greatly from this feature. Furthermore, lithium batteries maintain a nearly constant voltage during discharge and have a slow self-discharge rate when not in use.
Some specialized lithium-based batteries, such as lithium-iodide (polymer) batteries, are designed for long-life applications that require reliability over many years, such as medical implants. Overall, the qualities of lithium-based batteries align well with the demands of high-performance electronic devices.
