Q : How long should a battery last?
A : Battery cycles 1,000 times. The normal wear and tear of the battery means the mileage will gradually shorten to 85% capacity over 500 charges.
About your LEKI Battery
LEKI uses Ternary lithium batteries, also known as NMC batteries which are composed of Nickel, Manganese, and Cobalt as their primary anode materials. They combine the advantages of lithium cobaltate, lithium nickelate, and lithium manganate, resulting in superior performance compared to single anode material batteries. The unique synergy between these three elements forms a superlattice structure, contributing to the battery’s stability and high discharge platform.
Composition and Characteristics
- Nickel (Ni): Enhances energy density and capacity.
- Manganese (Mn): Improves structural stability and thermal safety.
- Cobalt (Co): Boosts energy density and overall performance.
Advantages of Ternary Lithium Batteries
- High Energy Density: Allows for longer usage times between charges.
- Long Cycle Life: Ideal for applications requiring longevity, such as electric vehicles.
- Good Performance: Efficient in various temperatures and capable of high charging and discharging rates.
Safety Considerations
Safety is a critical aspect of ternary lithium batteries, and several measures are in place to ensure their safe operation:
- Thermal Stability: The manganese component enhances thermal stability, reducing the risk of thermal runaway, where the battery’s temperature rapidly increases, potentially leading to fire or explosion. However, proper management is essential to prevent thermal issues.
- Battery Management System (BMS): A robust BMS monitors and manages the battery’s health, temperature, and charge/discharge cycles, preventing overcharging, over-discharging, and overheating.
- Quality Control*: Adhering to stringent manufacturing standards ensures the safety and reliability of the batteries, including proper material handling and thorough testing.
- 4. Proper Usage: Following manufacturer guidelines for charging, discharging, and storage conditions is crucial. Exposure to extreme temperatures, physical damage, or improper handling can compromise safety.
While ternary lithium (NMC) batteries offer superior energy density and balanced performance, they require careful management to ensure safety. Proper thermal management, robust battery management systems, and adherence to usage guidelines are essential. Compared to other battery types, NMC batteries provide a good compromise between energy density, cost, and safety, making them a reliable choice for many modern applications, including those at LEKI Australia.
