The packaging of lithium-ion batteries is divided into two categories: metal shell batteries and pouch batteries. The production process of lithium battery pack cells is divided into three major stages: electrode production, cell production, and battery assembly.

Currently, many electric vehicle owners encounter the situation where their vehicles are still functioning, but the battery’s range is insufficient. As a result, many citizens choose to replace the battery, with some opting for second-hand electric vehicle batteries to save

The May 26th accident in Shenzhen severely affected the reputation of the domestic electric vehicle brand, BYD, as their battery safety became deeply questioned.

As the core component of a car's electrical system, the battery's performance directly impacts the vehicle's starting efficiency and the functionality of electrical devices. For a new car battery, the first charge is particularly important as it determines the battery's capacity and lifespan. However, many users neglect this step, failing to fully activate the battery's chemical reactions, which results in suboptimal performance.

In modern technology, NiMH (Nickel-Metal Hydride), NiCd (Nickel-Cadmium), and Li-Ion (Lithium-Ion) batteries are widely used, each with distinct strengths and limitations.

Battery technology plays a vital role in modern life, especially in portable devices, electric vehicles, and renewable energy storage systems. Despite significant advancements in battery technology, the memory effect remains a concern.

In the early days of telecommunication server rooms, a common approach was to rectify the 220V AC power supply, charging a 48V battery​ set, which would then directly power the exchange switches.
