Differences Between LTO and Li-Ion Pin-Type Batteries
While both lithium-titanium-oxide (LTO) and lithium-ion (Li-Ion) batteries fall under the same “pin-type” category, they have distinct features and performance characteristics:
LTO Pin-Type Batteries
- Chemistry: Uses lithium titanate as the anode material, offering higher thermal stability and better performance in extreme conditions.
- Cycle Life: LTO batteries have a much longer cycle life than traditional Li-Ion batteries, often exceeding 3000 cycles.
- Charge Time: LTO batteries have a rapid charging capability, making them ideal for applications where quick power-up is required.
- Applications: They are typically used in space-constrained environments like small circuit boards and medical devices.
Li-Ion Pin-Type Batteries
- Chemistry: Traditional Li-Ion batteries use graphite as the anode material. They offer excellent energy density but with a comparatively shorter cycle life than LTO.
- Cycle Life: Generally around 500 cycles, depending on the usage pattern.
- Charge Time: Li-Ion batteries charge quickly but not as fast as LTO batteries.
- Applications: Commonly used in wearables, IoT devices, and other consumer electronics.
