Lead-acid batteries have a lower energy density (30-50 Wh/kg) and specific energy (20-50 Wh/L) compared to lithium-ion batteries (150-200 Wh/kg and 250-670 Wh/L, respectively). This implies that lithium-ion batteries can store more energy per unit of weight and volume, making them more suitable for portable and lightweight applications.
Battery capacity, the amount of energy a battery can store and discharge, is where lithium-ion batteries shine due to the advantageous chemical properties of lithium. They offer significantly higher energy density compared to lead-acid batteries, providing 20 to 50% more usable capacity, depending on the discharge rate. This means more energy ...
This type of lead–acid battery is designed to have high power density, but it has low total energy content and is not designed for applications that require energy delivered for long periods of time. It can also not handle deep discharge. The car battery normally operates with depth-of-discharge (DoD) of only 20%. Under those conditions, the cycle life of a car …
