Lithium Sulphur Battery Advantages And Disadvantages

From:CTECHI GROUP Limited     Release time:2018-10-11

Overview:The energy density of Li-So2 battery can reach 300W. H/kg (480W. H/dm'), which is more than 3 times of the best zinc manganese battery. Because of the low internal resistance of the coil cell, the discharge voltage is almost unaffected by the discharge rate, and its value is in the range of 2.7-2.9 V. From the typical discharge curves of D-type battery (internal resistance is 0.8Q) under different loads, it can be seen that the curves are very flat, almost no voltage lag. Even when the temperature is as low as -40 C, the voltage hysteresis is minimal. When the temperature is as low as -54 C and up to 70%, the battery can still work, while the ordinary battery don't work at -54 C. This type of battery can provide a pulse current of about 30A, and the voltage is not less than 2V. The storage life of the battery is very long. At room temperature, the capacity loss of the battery for more than 5 years is less than 10%.

Lithium Sulphur Battery Advantages And Disadvantages

Non rechargeable LiSO2 batteries, the batteries are made into cylindrical shape with a capacity range of 1 30Ah. It is divided into two discharge rate systems of standard rate and high magnification. Standard batteries have a wide range of loads and temperatures, while high-rate discharge batteries can produce high energy at low temperatures. Batteries are often produced in the form of battery pack. High energy density and less limited operating conditions make it suitable for military applications, including portable radio transceivers, night vision equipment, sonar, missiles and artillery devices; civilian emergency systems, alarms, aircraft emergency locators and so on. In 1995, NASA's Galileo probe, after six years of flight, entered Jupiter's atmosphere and sent long-range measurements back to Earth via an orbiter. The side detector uses three battery packs, each containing 13 LiSO2 Primary Lithium Batteries, with a capacity of 18 A "h. It is mainly used in the final flight period and thereafter more than 360g of deceleration.

Non rechargeable LiSO2 batteries has the advantages of high energy density, high power density, good voltage stability, excellent low temperature performance and long storage life. However, if the battery is not used properly, the battery will explode or release toxic gas. When the battery is in high temperature and the short circuit time is too long inside or outside the battery, the internal pressure will be too high, even reach the dangerous value. In addition, the glass metal seal will corrode at 60 OC for a long time. LiSO2 Primary Lithium Batteries must be equipped with electronic protection devices, such as current limiting devices or fuses, and diodes and thermal switching elements that prevent reverse charging of the battery. Batteries must also have a relief valve that releases air pressure when the internal pressure exceeds the critical value of the housing design.

Stricter safety standards, especially improved sealing and safety valve technology, are required during the transition from military to civilian applications. Before the battery system is popularized, the lithium sulfur dioxide battery disposal should also be considered.
