Telecommunication Emergency Portable Power Supply

At present, power supply time of backup power is not long on telecommunication base station after the failure of electricity supply. In view of this, Sacred Sun has developed a kind of emergency portable power supply that could replace oil engine. 

    Sacred Sun newly developed 51.2V lithium ion battery power supply system---Telecommunication Emergency Portable Power Supply, adopts scientific internal design, advanced battery production technology, reliable BMS design. All of these ensure the system’s high-energy-density, long service life, safe and reliable, and wide applicable temperature range, hence, it is the ideal emergency power supply system for telecommunication base stations.

 The features of the power supply as below:

1. Super long service life, more than 4000 cycles at 80% DOD;

2. Wide applicable temperature range, could discharge normally at - 20 ~ 55 ℃;

3. Quick charging is available; the recommended charging time is 1-2 hours;

4. Customized products are available to meet the customers’ requirements;

5. Small volume and light weight to achieve easy carrying, push and pull are both available;

6. The operation is simple and easy to learn, such as starting up and connection;

7. Products are safe and reliable, and already passed on-site verification and validation.

                                                              

Lithium-sulfur Battery

     Lithium-sulfur (Li/S) battery is a kind of rechargeable battery adopts lithium as negative electrode and elemental sulfur as positive active material. The theoretical specific capacity of its positive electrode is expected to reach 1675mAh/g, and the theoretical specific energy of the Li/S battery is expected to reach 2600Wh/kg. Its achievable practical energy density may reach 750Wh/g.
    In accordance with the report published at Phys.org on January 13th, 2015, the new material discovered by chemistry professor Linda F. Nazar and her research team could maintain the stability of Sulfur cathode, which is the major obstacle in the research of lithium-sulfur battery. Theoretically, the running time of lithium-sulfur battery is 2 times longer than that of ordinarylithium ion battery at same weight. What’s more, it’s cheaper than lithium ion battery.
     In July 2010, lithium-sulfur battery produced by Sion Power is applied on an American unmanned solar plane, which has attracted the attention of the public. Part of the electricity generated at daytime is stored in the lithium-sulfur batteries and discharged at nighttime. The unmanned solar plane has flown 14 days continuously.

                                                            

Recycling of battery: applying used EV batteries into power grid

    Plug-in electric vehicles(PEVs) show enormous potential in reducing the consumption of fossil fuels and the emission of greenhouse gases. However, its relatively high price, which mainly comes from the battery system, impedes its popularization in market. Some researchers put forward that if the secondary use of EV batteries is achieved, it may offset part of the cost of electric vehicles. Researchers from US NREL play an important role in the identification of "the secondary use of EV battery".

    As PEVs energy storage device, Lithium ion battery is usually the most expensive part of electric vehicles, which still has some environmental pollution problems in the processing of used batteries.

   The secondary use of EV batteries could not only expand the application of electricity, but also promote the extensive application of PEVs. What’s more, their application in energy storage power gird could also supplement the electricity demand of the grid at peak times and help to create a cleaner and more flexible grid. NREL has confirmed that a capacity of 70% initial capacity is kept in the used lithium-ion batteries, which enables us to use their electrode materials again.
