Lithium-Polymer vs Lithium-Ion: Why Verbatim Chooses the Lithium-Polymer
Why what’s inside your power bank matters
We all rely on portable power to stay connected, whether that’s charging your phone on the go, powering up your tablet for study, or keeping your earbuds ready for a commute. But have you ever stopped to think about what’s inside your power bank?
Most power banks use either lithium-ion (Li-Ion) or lithium-polymer (Li-Po) batteries. Both are rechargeable and lithium-based, and Li-Po is a variation within the lithium-ion family. The differences lie in the cell’s structure, its electrolyte and its design, and they affect how a power bank is built and how it performs.
What’s the difference between Lithium-Polymer and Lithium-Ion batteries?
Both types store and release energy by moving lithium ions between two electrodes. The electrolyte is the medium the ions travel through.
- Lithium-ion batteries typically use a liquid electrolyte, held in rigid cylindrical, prismatic or pouch cells. They’re efficient, widely used and cost-effective.
- Lithium-polymer batteries typically use a gel or polymer-based electrolyte in a flexible pouch cell. Many still contain some liquid within the gel. This structure allows slimmer, lighter and more adaptable designs.
Neither type is automatically safer. The overall design, materials, manufacturing quality and protection circuitry all matter.
Why Verbatim chooses lithium-polymer
✅ Design flexibility. Pouch cells can be made thin and shaped to suit the product, which is how our power banks stay slim enough for a pocket or handbag.
✅ A more controlled electrolyte structure. The gel or polymer-based electrolyte holds more of the electrolyte in place than a free-flowing liquid does. That can help stability, although it doesn’t make a battery fireproof. As with any lithium battery, damage, defects or misuse can still cause problems.
✅Built-in protection circuitry. Every Verbatim power bank includes safeguards against overcharging, over-discharging, overcurrent, short circuits and overheating.
Whether it’s in your backpack, car or classroom, Verbatim power banks are designed with safety built in at every level.
Slimmer, lighter, and smarter design
Because lithium-polymer cells are flexible and lightweight, they can be moulded into thinner shapes. That’s why Verbatim’s Charge’n’Go power banks are compact enough to slip easily into a pocket or handbag without adding extra bulk. They suit:
- Students and teachers who need reliable power on the go
- Commuters and travellers packing light
- Professionals juggling multiple devices throughout the day
More power. Less weight. No compromise.
What about battery lifespan?
All rechargeable batteries wear over time. How long a power bank lasts depends on the quality of its cells, how often you charge it, the temperature it’s used and stored at, and how you treat it. Avoiding heat, using certified cables and chargers, and not leaving it fully charged and plugged in for long periods will all help.
What’s next? Semi-solid-state technology
The newest development in power bank batteries is semi-solid-state, which holds even more of the electrolyte in a gel-like structure. Our SnapQub Wireless Power Bank is the first in Verbatim’s semi-solid-state range. To find out what the term means, what it does and what it doesn’t, read our guide to semi-solid-state power banks.
The Verbatim difference
Verbatim has been powering everyday technology for decades, from data storage to portable power. Every Charge’n’Go power bank is built with premium lithium-polymer cells and intelligent protection circuits against overcharging, over-discharging, overcurrent, short circuits and overheating.
When it comes to safety and reliability, Verbatim simply doesn’t compromise. Because life works better with Verbatim, no matter where you are or what you’re doing.
