Types of battery packs
The main types of battery packs include lithium-ion battery packs, nickel metal hydride battery packs, and lead-acid battery packs, each with its unique characteristics and application scenarios. ‌‌

Lithium ion battery packs are currently one of the most commonly used types of battery packs, with advantages such as high energy density, long lifespan, and low self discharge. They are widely used in portable devices such as mobile phones, laptops, and tablets, and are gradually being applied in fields such as electric vehicles and electric bicycles. Nickel metal hydride battery packs (NiMH) have high energy density and good low-temperature performance, making them suitable for devices that require high current output, such as digital camera flashes and power tools. Lead acid battery packs are a more traditional type, mainly used to start the engines of vehicles such as cars and motorcycles, and can also be used as uninterruptible power supplies (UPS) or emergency power sources. Although their energy density is low, they are relatively inexpensive.

In addition, there are other types of battery packs, such as nickel cadmium battery packs and sodium sulfur battery packs. Nickel cadmium batteries have good high current discharge capability and overcharge resistance, but there is a “memory effect” that may shorten their service life and cause environmental pollution. Sodium sulfur batteries have high specific energy and high charge discharge efficiency, suitable for high current and high-power discharge, but they are costly and pose safety risks.

With the development of technology, new battery technologies continue to emerge, and the types and application areas of future battery packs will also continue to expand, bringing more convenience to people’s lives.
