1. Lithium ion batteries have the advantages of large capacity and high operating voltage.The battery has twice the capacity of an equivalent nickel-cadmium battery, making it more suitable for long-term communication.Conventional lithium-ion batteries have a voltage of 3.7v, three times that of nickel-cadmium and nickel-metal hydride batteries. 2. Strong charge holding capacity, allowing for a wide operating temperature range.After 30 days of open storage at (20±5)℃, the discharge capacity of the battery at room temperature is greater than 85% of the rated capacity.Lithium ion battery has good high temperature and low temperature discharge performance, can be in - 20 ˉ + 60 ℃, high temperature and discharge performance is higher than other types of cells. 3. Long cycle life.Lithium-ion batteries use carbon anodes.During charge and discharge, the carbon anode does not produce dendrite lithium, thus avoiding the damage of internal dendrite lithium short circuit to the battery.After 1200 consecutive charges and discharges, the battery capacity is still not less than 60% of the rated value, far higher than other types of batteries, with long-term use economy. 4. High safety, safe and fast charging and discharging.Compared with metal lithium batteries, lithium ion battery short circuit resistance, resistance overcharge, discharge, shock, vibration, shooting, acupuncture, no fire, no explosion, and so on, because it has special carbon anode electrode instead of metallic lithium electrode, thus allowing quick charge and discharge, can be in 1 c rechargeable battery charging and discharging, greatly improve the safety performance. 5. No environmental pollution.Batteries are free of harmful substances such as cadmium, lead and mercury, making them a clean "green" source of chemical energy 6. No memory effect.It can be reused at any time, especially in wartime and emergency situations. 7. Small size, light weight and high energy.In general, lithium-ion batteries have more than twice the specific energy of nickel-cadmium batteries.Compared with similar capacity nickel-metal hydride batteries, the volume can be reduced by 30%, weight can be reduced by 50%, which is conducive to small and light portable electronic devicesLow cost, high performance, high power, high safety and environmental protection are the development direction of lithium ion batteries.As mentioned above, lithium ion battery, as a typical representative of a new type of energy, has obvious advantages, but at the same time, there are some shortcomings that need to be improved.
Application scope of lithium battery UPS power supply:Banking systemThe UPS power supply used by the bank is generally very high, and the selected UPS should have very reliable quality and high average trouble-free time. At the same time, there should be a remote operation monitoring interface, which can be monitored remotely by operators on duty or UPS maintenance personnel.Lithium battery UPS power supply is a new solution.The banking system is the largest user of lithium battery UPS, accounting for almost 40% of the whole UPS power supply sales. In the future, it will be a development trend for the banking system to adopt lithium battery UPS energy storage.Medical equipmentIn medical equipment, available lithium battery UPS type organic UPS.Because the hospital USES a variety of medical equipment more, and the power is generally larger, resulting in the hospital's power frequency fluctuations are larger, the power environment is bad.In addition, hospitals are lifesaving places, so medical equipment must be available at all times so as not to delay the emergency treatment of patients. After all, UPS equipment is valuable while life is priceless.Data centerAt present, it is particularly important for the data center industry to maximize the use of existing space and minimize operating costs, especially for UPS power cooling energy consumption, battery maintenance and battery replacement service costs.Lithium battery UPS is the key to solve these problems because of its excellent performance.Lithium batteries are also lighter, reducing the total weight of a modular data center, making it easier and cheaper to transport to the installation site.
