Voltage Comparison: 3.7V vs 3.8V Batteries

Different Nominal Voltages

3.7V Lithium Battery: The nominal discharge platform voltage is 3.7V, the full charge voltage is typically 4.2V, and the discharge cutoff voltage is generally 3.0V.

3.8V Lithium Battery: The nominal discharge platform voltage is 3.8V, with some models reaching a full charge voltage of 4.35V. The discharge cutoff voltage is still mostly set at 3.0V or slightly higher.

Higher Energy Density (3.8V)

3.8V batteries typically use advanced cathode materials such as high-nickel ternary lithium batteries, allowing them to store more energy in the same volume or weight, resulting in higher energy density. They are suitable for devices with high battery life requirements.

Application Scenarios Differences

3.8V Batteries: Primarily used in high-end smartphones, tablets, high-performance wearable devices, drones, and other products sensitive to voltage stability and energy density.

3.7V Batteries: Widely used in general consumer electronics, such as remote controls, toys, and basic Bluetooth devices, in scenarios where cost is sensitive and power requirements are low.

Cost and Safety

3.8V Batteries: Due to more complex materials and processes (such as high-voltage electrolytes and precision BMS), they are more expensive; at the same time, due to higher operating voltages, they have a slightly higher risk of thermal runaway and require more stringent battery management systems (BMS).

3.7V Batteries: These are technologically mature, have lower costs, and offer relatively easier safety assurance, making them suitable for mass-market products.
