India continues to ramp up interest in ESS technology

India signalled its growing interest in energy storage systems during a week when its prime minister visited Tesla and a firm unveiled a new lead-acid battery.
During a tour of the US firm’s automotive campus, Indian Prime Minister Narendra Modi showed interest in Tesla’s Powerwall, especially for India’s remote rural areas.
India’s Ministry of External Affairs said the main takeaway was the technology behind long-term storage batteries, and Modi had been ‘very keen’ to see how India could use the battery technology to ‘leapfrog development in India’, claimed the website.
Tesla began shipping its 7kWh Powerwalls to pilot customers in North America, Germany, Austria, Switzerland, and Australia this week.
Meanwhile Relicell has launched a proprietary gel-based maintenance-free battery, designed for renewable energy storage, especially for home use in India’s punishing weather conditions.
Relicell is the battery brand of Greenvision Technologies, an energy storage solutions firm headquartered in Bangalore, India.
The batteries use a lead-calcium-tin-silver alloy, a synthetic separator with phosphoric acid added to the electrolyte to improve life cycle.
The batteries are available in 12V, 35 Ah to 12V and 200 Ah options and come in three variants: Solar Gel for solar applications, Ultra Gel for home inverters and deep cycle UPS applications.
Founder and Managing Director of Greenvision Technologies Biju Bruno said: "The largest adoption of these batteries is likely to be in home inverters and solar energy storage devices, while batteries used to store solar energy will be able to operate under very hot conditions and even in a state of partial charge."
Back in August ACME Cleantech Solutions launched the first power back-up storage solution in India. The lithium-ion-based EcoGrid Energy Storage System was designed for homes and small commercial units.
At the start of the year, US energy storage system developer SunEdison moved into the Indian market when it bought 1,000 Imergy Power Systems ESP 30 systems.


SunEdison bought the vanadium flow battery technology to build microgrids to store solar energy in rural India. SunEdison aims to develop 5,000 microgrids by 2020 to store solar energy for 20 million people, with the first 1,000 to be developed within three years.

   1). Solar-cell Array. It is the core component of the system, convert solar energy into electric energy. The solar cell modules are installed in series or in parallel in accordance with the requirements of different systems.
   2). Battery. Store the electric energy generated by solar-cell array so as to supply power at the following conditions: light deficient conditions, nights, or when load demand is higher than power supply of the array. The most widely applied batteries in PV systems are lead acid batteries.
   3). PV Controller. It is the core control section of the whole system, controlling the charge/discharge of batteries and the electrical power output of the array and battery pack. Currently, there are mainly two widely applied control modes: PWM and MPPT. The PWM has higher control efficiency but relatively lower utilization rate to solar modules; while MPPT has relatively lower control efficiency but higher utilization rate to solar modules. In most cases, PWM mode is applied in system with smaller power, and MPPT mode is applied in system with lager power, especially when system power is higher than KW level.

   4). Inverter. If AC Load is included in the system, inverter is needed to concert direct current from solar-cell array or battery pack into needed alternate current.

Graphene Battery

Graphene’s huge specific surface area enables it to carry more li-ions and get/loss li-ions more quickly, therefore provides the essential physical foundation for battery to have bigger capacity and quicker charge/discharge speed.
   Battery with graphene as negative electrode has very good charge/discharge rate but very bad cycle life. Researchers are always trying to find an appropriate negative electrode material so as to combine advantages such as fast charging/discharging, long cycle life, high energy density and low cost together.
Graphene Battery
    Recently, Spain’s El Mundo has reported that Spain’s university has developed a graphene battery which has combined all the above advantages together. It will be first tested in a German’s automotive enterprise.
    On condition that the report is true, this battery will be quite promising. If the recharging time is as short as refueling time, then the charging stations could take the place of gas stations, and electric vehicles could take the place of fuel vehicles.
Conclusion
    Everything real is rational. The lead acid battery and lithium batteryhttp://www.sacredsun.com/productsdetaillithium_125_125_125_125.html are still dominating the market of electric vehicles, not because the manufacturers are stupid, but for other technologies are not mature or lack supporting industrial chain.

    We need to be patient to wait for the next breakthrough in this area.

Flow Battery

 Flow battery belongs to ordinary chemical battery. Its utilization rate of active materials is improved through storing positive electrolyte and negative electrolyte separately.
      Due to the limit of materials and the concentration of the electrolyte, the flow battery didn’t achieve high energy density in past years. It can be applied in energy storage power stations, but not available on vehicles.
     Recently, Dr. Yet-Ming Chiang, scientist of Massachusetts Institute of Technology, has invented a semi-solid lithium flow battery. He has made innovations on material and electrolyte concentration, which enables the battery to reach applicable level on energy density and power density. This battery is still in the laboratory stage.
    NanoFlowcell AG has launched an automobile with flow battery, which seems have reached very high energy density in accordance with its technical index. However, its facticity remains to be verified.
Flow Battery    Compared with previous hydrogen fuel battery and metal fuel battery, flow battery is more feasible. Once the laboratory technology enters into mass production period, it will change the electric vehicle industry dramatically. With flow battery, electric vehicle could run further, become cheaper, and charge faster (charge through power grid or replace electrolyte).

Sacred Sun: Energy Storage System of FCP Lead Carbon Batteries will Assist the Development of Energy Storage Industry

On March 16th, 2015, the second working conference of “13th Five Year Plan” on the development of national energy storage industry was held at Tsinghua University. Experts have fully discussed 7 major topics and 33 subtopics on technologies, development objectives, tasks, and overall arrangement of energy storage industry.


    Aiming at the cost dilemma happened in the scale development of energy storage industry, Sui Yanbo, deputy general manager of Sacred Sun, has indicated that FCP lead carbon batteries could improve the development of energy storage industry with its advanced technology and less cost per kw.h.

    Sacred Sun has brought in advanced FCP lead carbon battery technology from Japanese company Furukawa Battery Co., Ltd. in 2014. Such kind of battery possesses advantages such as superlong service life, better charge acceptance, excellent PSOC property, modularized system design and installation, etc.
    At last, Mr. Sui said that Sacred Sun is willing to cooperate with experts responsible for the major research projects of “13th Five Year Plan” on the development of energy storage industry, and make greater contributions to the energy revolution of our country.

The World is Entering “Aluminum” Battery Era

Recently, ChineseAmerican scientist Dai Hongjie has developed a high- performance aluminum battery which is suitable for commercial applications. Smartphones with such kind of batteries can be fully charged within 1 minute and without capacity loss within 7500 chargedischarge cycles. On the strength of its faster charging, longer service life, and lower cost, it is very possible for aluminum batteries to replace Lithium-ion batteries and alkaline batteries in the future.
    In the past decades, researchers are always trying to develop economical aluminum batteries, but appropriate positive materials and electrolyte materials are too difficult to find.
    In accordance with the report from American’s Science Daily website on April 6, negative electrode (aluminum material), positive electrode (graphite), and electrolyte (ionic liquid) of aluminum battery are placed in a soft bag made of aluminum foil and covered by flexible macromolecules.

     “This newly developed rechargeable aluminum battery is much safer than traditional Li-ion battery. Li-ion battery has the risk of explosion, while aluminum battery is safe on this aspect. In addition, to fully charge a smartphone with Li-ion battery, several hours are needed, while for smartphone with aluminum battery, one minute is enough.”
    Compared with the service life of other aluminum batteries (approximately 100 charge-discharge cycles) and Li-ion batteries (approximately 1000 charge-discharge cycles), the service life of this new aluminum battery (7500 charge-discharge cycles without capacity loss) is really amazing.
    Another distinguishing characteristic of this new aluminum battery is its flexibility, which enables it to be applied on flexible electronic instruments. Cheaper, safer, greener, and more flexible, this aluminum battery is a perfect alternative for traditional alkaline batteries and li-ion batteries.
    The only deficiency of this new aluminum battery is its voltage, which is only half of traditional li-ion batteries. Dai Hongjie planned to improve its voltage and energy density through improving the performance of positive materials.
