Types of Batteries Used in Power Banks
Power banks typically use one of two types of batteries: lithium-ion (Li-ion) or lithium-polymer (Li-poly). Li-ion batteries are the most common type used in power banks due to their high energy density, long cycle life, and relatively low cost. Li-poly batteries, on the other hand, offer improved safety features, flexibility, and a lower risk of explosion. However, they are generally more expensive than Li-ion batteries and have a lower energy density.
Chemical Composition and Reaction
To understand why power banks bloat, it’s crucial to grasp the chemical composition and reaction that occurs within the battery. Li-ion batteries consist of a positive cathode, a negative anode, and an electrolyte that facilitates the flow of ions between the two electrodes. When a Li-ion battery is charged, lithium ions move from the cathode to the anode, and when it’s discharged, the process is reversed. This continuous flow of ions can cause the battery to degrade over time, leading to a range of issues, including bloat.
