Why do Mobile Power Sources Start Using Li Polymer Battery

Mobile power sources, such as portable chargers or power banks, have increasingly started using Li-Polymer batteries due to several advantages they offer over other battery types. Here are the main reasons for the adoption of Li-Polymer batteries in mobile power sources:

1. High Energy Density: Li-Polymer batteries have a higher energy density compared to other battery technologies like NiMH (Nickel Metal Hydride) or Li-Ion (Lithium-Ion) batteries. This means that Li-Polymer batteries can store more energy in a smaller and lighter form factor, allowing mobile power sources to be compact and lightweight while providing ample power capacity.

2. Slim and Flexible Form Factor: Li-Polymer batteries are known for their slim and flexible form factor. They can be manufactured in various shapes and sizes, making them adaptable to fit the compact and often unique designs of mobile power sources. This flexibility in form factor allows for efficient space utilization within the power source, making it more portable and convenient for users.

3. Improved Safety: Li-Polymer batteries have a lower risk of leakage and thermal runaway compared to other battery types. They use a solid polymer electrolyte instead of a liquid electrolyte found in traditional Li-Ion batteries. The solid electrolyte provides better stability, reduces the risk of electrolyte leakage, and enhances the overall safety of the battery. This is particularly important for mobile power sources that are frequently transported and subjected to various environmental conditions.

4. Lower Self-Discharge Rate: Li-Polymer batteries have a lower self-discharge rate compared to other rechargeable battery technologies. This means that they can retain their charge for a longer period when not in use. Mobile power sources equipped with Li-Polymer batteries can thus hold their charge for longer durations, ensuring that they are ready to provide power when needed, even after being idle for extended periods.

5. Faster Charging Capability: Li-Polymer batteries generally support faster charging rates compared to other battery types. They can accept higher charging currents, allowing mobile power sources to be charged more quickly. This feature is beneficial for users who require a rapid recharge of their power sources to minimize downtime and ensure they have power readily available.

6. Longer Cycle Life: Li-Polymer batteries typically offer a longer cycle life compared to other rechargeable batteries. A cycle refers to one complete charge-discharge cycle of the battery. Li-Polymer batteries can endure a higher number of charge-discharge cycles before their capacity significantly degrades. This longevity ensures that mobile power sources with Li-Polymer batteries can provide reliable power for an extended period, making them more durable and cost-effective in the long run.

Due to these advantages, Li-Polymer batteries have become a popular choice for mobile power sources. Their high energy density, slim form factor, improved safety, lower self-discharge rate, faster charging capability, and longer cycle life make them well-suited for powering portable devices and providing convenient on-the-go charging solutions.
