Will sodium-ion battery replace Li-ion battery?

    Not satisfied with changing the appearance of lithium battery, John Goodenough, father of Li-ion battery, has now organized an international team of scientists at the University of Texas, US. Currently, the team has claimed that the mineral eldfellite ( NaFe(SO4)₂) could be regarded as a potential cathode for sodium-ion battery. This significant discovery has been published on an online Journal called Eldfellite. The title of the paper is “NaFe(SO4)₂: Embedded Cathode for Low-cost Sodium-ion Batteries”.
    Eldfellite (NaFe(SO4)₂) is composed of Na⁺ layers and Fe³⁺ layers, and is separated at a fixed distance by SO4^2-polyhedral. 80% of the material’s theoretical maximum specific capacity might be achieved because the fixed spaces allow the diffusion of sodium ions.
    Preetam Singh, a scientist of the research team, said that the problem at present is the size of the sodium ion, because the sodium–sodium interaction is much stronger than Lithium-Lithium interaction. If they simply duplicate li-ion technology by directly replacing lithium with sodium in the chemical structure of cathode and electrolyte, favorable ratio performance will not be achieved.
    Li-ion batteries bring us convenience, such as mobile phones and electric vehicles. However, the limited supply of lithium has caused the high cost of li-ion batteries and EVs, and has confined the application of the technology.
    In view of the deficiency of lithium, researchers are trying to solve the problem through replacing lithium with sodium, for sodium-ion battery could also reach 100% discharge rate and is safer than lithium-ion battery on transportation.

An intelligent energy storage power plant exclusively designed for you

    As a new energy storage pattern, containerized energy storage system mainly contains battery packs, energy storage converter (PCS), battery management system (BMS), SCADA & EMS, container-type pre-fabricated chamber, and some aid control systems. Such kind of system of Sacred Sun is extensively adopted in electric power, industry, and commerce fields on account of its patent thermal control technology, flexible configuration of energy storage devices, high security design, long life in extreme environment, modularized design, and favorable extendibility.

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.

Will water-based “green” lead recycling method become the future trend?

   The world’s first “green” lead-acid battery recycling plant will be situated in America, which is expected to eradicate the polluting reputation of lead smelting. The America-based new company Aqua Metals plans to replace conventional smelting method with a water-based “greener” method based on its AquaRefining technology.
   The 33 patents related to the AquaRefining technology will not be released to the public before they are approved. Based on what we have known, electrowinning will be included in this technology. By adopting this technology, 30% energy will be saved compared with the traditional method, and no toxic waste (molten slag, lead dust or sulfur dioxide) will be generated during the process. What’s more, extendable lead electrolyzing modules will be adopted.
   Steve Clarke, CEO of Aqua Metal, stated that one of the merits of their technology is its much smaller economic scale compared with conventional smelting method. If everything goes well, its plant TRIC located in Nevada will be able to produce 80 tons secondary lead every day, and its super plant at Tesla will be completed at the middle of 2016.
  Aqua Metal has developed cooperative relationships with Wirtz Manufacturing and Battery Systems, which are responsible for manufacturing pulverizing systems and providing waste batteries respectively.
   The company plans to build more plants in America and Europe, and develop cooperative relationships with battery manufacturers and lead manufacturers in those areas and other regions around the world.

Sacred Sun lead carbon batteries’ application in communication base station

    

    Nowadays, the general electric power conditions in China is continuously improving. In many communication base stations with relatively good power conditions, huge resources are wasted for batteries always run under floating charge mode and seldom discharge during their lifetime. Furthermore, big electricity peak valley difference and high electricity price in those areas also lead to higher base station electricity fees.

    In view of this, Sacred Sun has upgraded its backup power system based on the excellent cycle performance of its FCP lead carbon battery. On the premise of ensuring the safe operation of battery packs, the system could also make contributions to peak load shifting under PSOC operation. Specifically speaking, on the one hand, the system could monitor the real-time health status of the battery packs, and enable the operator to carry out preventative maintenance timely and therefore guarantee the reliability of the system; on the other hand, the system could be applied to peak load shifting to relieve the imbalance of power load and achieve low-carbon operation.
