Advantages of 18650 Li-ion Battery compared with Ni-MH battery

Higher Energy Density

18650 Li-ion batteries offer significantly higher energy density (150-265 Wh/kg) compared to Ni-MH (60-100 Wh/kg), storing more energy in the same weight/size. This allows devices to be lighter and more compact for the same capacity (e.g., 2000-3500mAh in a standard 18650 form factor).
Higher Nominal Voltage

Li-ion cells provide a nominal voltage of 3.6-3.7V per cell, nearly three times that of Ni-MH (1.2V). Fewer cells are needed to achieve the same system voltage, reducing weight, complexity, and cost in battery packs (e.g., a 7.4V system requires 2 Li-ion cells vs. 6 Ni-MH cells).
Lower Self-Discharge Rate

Li-ion batteries self-discharge at only ~5-10% per month (vs. 20-30% for Ni-MH), retaining charge better during storage. This is critical for devices used infrequently (e.g., emergency equipment) or requiring long shelf life.
No Memory Effect

Li-ion cells do not suffer from the "memory effect," where repeated partial charging reduces capacity over time. They can be charged at any state of charge without performance degradation, offering user-friendly flexibility.
Longer Cycle Life

18650 Li-ion batteries typically offer 300-500 charge-discharge cycles (some high-quality cells up to 1000 cycles) when properly managed, compared to 200-300 cycles for Ni-MH, making them more cost-effective long-term.
Lighter Weight

For the same capacity, Li-ion cells are ~30-50% lighter than Ni-MH, crucial for portable devices where weight reduction enhances mobility (e.g., laptops, drones, electric vehicles).
Environmentally Friendlier

Li-ion batteries are free of toxic heavy metals like cadmium (found in Ni-Cd) and have lower nickel content than Ni-MH. They are more recyclable and have a smaller environmental footprint, though proper disposal is still required.
