1. Strong navigability. Although the weight of the medical lithium-ion battery pack is only 30% of that of the lead-acid battery, the medical lithium-ion battery has stronger continuation ability under the same voltage and capacitance.
2. Good low temperature discharge performance, medical lithium-ion battery pack can work normally at -25 degrees Celsius, but lead-acid batteries can work normally at a minimum of -10 degrees Celsius.
3. Long duration of charging: the capacity of a fully charged medical lithium-ion battery is still more than 80% in idle months, and the capacity of a lead-acid battery is only about 40%.
4. Long cycle life: The number of charge and discharge times of medical lithium-ion batteries is more than 500 times, and the discharge reaches 1C, while the discharge of lead-acid batteries is only 0.5C, and the service life is 300 times.
5. High specific energy: due to the small volume of the lithium-ion battery pack, but the storage capacity is large;
6. The normal working temperature range is wide: the working temperature of the medical lithium-ion battery pack works in the range of -25 to 55 degrees, and the lead-acid battery works in the range of 10 to 40 degrees.
7. High current efficiency: Unlike any previous secondary battery in aqueous solution, lithium-ion battery packs do not produce gas during normal charging and discharging, and the current efficiency is close to 100%, which is particularly suitable for use as power storage and Converted battery pack.
8. Clean and pollution-free: The medical lithium-ion battery pack does not contain toxic substances such as lead, blessing, and mercury. At the same time, because the battery must be well sealed, very little gas is released during use, and it does not pollute the environment. The solvent used to dissolve the binder in the manufacturing process can also be completely recovered.
9. Low self-discharge rate: The lithium-ion battery pack adopts a non-aqueous electrolyte system, and the lithium-inserted carbon material is thermodynamically unstable in the non-aqueous electrolyte system. During the first charge and discharge process, a solid electrolyte interphase (SEI) film will be formed on the surface of the carbon negative electrode due to the reduction of the electrolyte, allowing lithium ions to pass through but not electrons, and makes the electrode active materials of different charge states. In a relatively stable state, it has a low self-discharge rate.
