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.

Off-grid PV System

1. The Composition of Off-grid PV System

    Figure 1 is the schematic diagram of a typical off-grid PV system.

Figure 1. Composition of Off-grid PV System

2. Major Components of Off-grid PV System

   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.

Sacred Sun has Broken Through Cost Predicament of Energy Storage System with Its Leading Technology

Hydrogen Fuel Battery

  In previous article, we have discussed the technical requirements for electric vehicle batteries and have briefly introduced the basic characteristics of Li-ion batteries and lead acid batteries. Start from this article, we will introduce several advanced batteries for you one by one. In this article, we focus on hydrogen fuel battery.

    Fuel battery is usually nonrechargeable. As a kind of fuel battery, the “charging mode” of hydrogen fuel battery is actually hydrogen filling.

   The advantage of hydrogen fuel battery is 0 pollutant emission. Hydrogen generates electricity, motor drives vehicle. We change gas stations into hydrogen refueling stations and everything seems to be Ok.

   However, the entire process is not as simple as what you see. One problem we need to consider is the manufacture, transportation, and storage of hydrogen. Gaseous hydrogen needs to be stored in high pressure gasholder while liquid hydrogen needs to be maintained at very low temperature which costs excessive consumption of electric energy. It is far more troubling than fuel oil.

    Manufacturing of hydrogen is relatively simple. But if you want to transport hydrogen to hydrogen refueling station, special pipelines are needed. Considering the hydrogen embrittlement, the transportation, storage, and refilling of hydrogen demand facilities with high security.

     For fuel oil and natural gas, we have existing infrastructures to utilize; for lithium battery, we have existing power grid to utilize; while for hydrogen fuel battery, we have nothing. If we plan to manufacture vehicles with hydrogen fuel batteries, we need to build an entire system from hydrogen manufacture, to transportation and storage first. It is really a costly project.

Which Battery is Best for New Energy Vehicle?

Recently, with the promotion of Tesla, more and more new-type batteries for new energy vehicles begin to enter the public consciousness: from hydrogen fuel battery, aluminum battery, to flow battery, grapheme battery, aluminum ion battery, ... It seems that Li-ion battery has been out of date. What on earth is the truth of electric vehicle batteries?

    Now, let’s uncover the truth of electric vehicle batteries.

    Battery is the core problem which limits the development of electric vehicle. For electric vehicles, ideal battery must possess following characteristics:

   1. Enough energy density (has enough capacity at per unit volume and per unit weight), so that the vehicle could run further;

    2. Enough power density (could generate enough power at per unit volume and per unit weight), so that the vehicle could speed up in a short time and achieve climbing;

    3. Fast energy supplements, no matter recharging or replacing;

    4. Low average cost, with competitive advantage on comprehensive analysis of service life and price.

    In current electric vehicle market, there are mainly two kinds of batteries: Li-ion batteries (LFP battery, LMO battery, ternary lithium battery) for high-speed electric vehicles, and lead acid batteries for low speed electric vehicles.

   For Li-ion batteries, the power density and energy density are satisfying, but its recharging time is long and price is relatively high. While for lead acid batteries, although its power density and energy density is relatively low and its recharging rate is slow, its low price result in its extensive application on low-speed and short distance electric vehicles.

   In following passages, we will introduce the advanced batteries mentioned above for you.

Progress of Sacred Sun’s Lithium-ion Battery

• In view of the fierce competition of Lithium-ion battery in the communication market, reducing cost and lowering price is the only approach to consolidate and increase our market share. To achieve the objective of cost reduction and meanwhile improve the property of our Lithium-ion battery, we have made great achievements in the following aspects:

  1. Dry blending technology is applied in powder mixing process to shorten ingredients preparation time and improve the uniformity and adhesion of plates;

  2. Dispersion technology of pigment industry is brought in to achieve the molecular-level dispersion of paste;

  3. Roughen the surface of the aluminum foil (positive electrode) and copper foil (negative electrode) to improve the adhesion of paste and foils, and thereby prolong the service life of batteries;

  4. Adopt LiFePO4 made from iron oxide red craft instead of LiFePO4 made from iron oxalate to reduce cost;

  5. Adopt ovens with high vacuum degree to shorten the drying time of plates and meanwhile make sure the property of products.

  

High Temperature Battery Assists the Energy Conservation and Emission Reduction

• High-temperature (HT) valve-regulated lead acid batteries manufactured by Sacred Sun are specially developed for standby power-supply systems and energy storage systems in high temperature environment. With excellent properties such as high temperature resistance, long service life, and reliability, HT batteries can be applied in BTS with environment temperature above 30 ℃ all the year round, BTS with frequent power failure, BTS in remote areas, solar energy storage systems, and wind energy storage systems.

   

      Sacred Sun’s HT batteries have been widely applied in Indoor and outdoor BTS of Jiangsu Telecom, Hainan Telecom, Hubei Telecom, Guangdong Unicom, Guangdong Mobile, Hunan Mobile, Yunnan Unicom, etc.

   

  

      In BTS with HT batteries, the temperature of air conditioners is improved from 25 ℃ to 35℃. After tracing the energy-saving effect of HT batteries in BTS for 1 year, we have found that the annual average electricity-saving rate of stations with high-temperature batteries has reached 63.9%.

  	BTS with HT Batteries	BTS with Ordinary Batteries
  Architectural Material of BTS	Brick	Brick
  Area of BTS	20 m2	20 m2
  Ambient Temperature of BTS	35℃	25℃
  Total Power of Air Conditioners	3.0kw	3.0kw
  Load of BTS	39A	38A
  Battery Type	2V500Ah: 1 set	2V500Ah: 1 set
  Daily Average Power Consumption of Air Conditioners	5.32 kwh /day	14.74 kwh /day
  Amount of Energy Saving (kwh)	9.42 kwh /day
  Energy Saving Rate	63.9%

      We assume that the air conditioner power consumption of the 3 three operators (China Mobile, China Telcom and China Unicom) is 30 billion kwh/year, then they can save 9.5 billion kwh/year. On account of the above data, HT batteries have demonstrated remarkable economic benefit and social benefit.

Capacity of Global Distributed Energy Storage Systems May Increase by 10 Times in Future 3 Years

    In accordance with data from Navigant Research---a well-known American market research firm, the capacity of global distributed energy storage systems will achieve 276 MW by 2015.

    With the increasing support from governments and increasing energy storage demands from grid operators and electric power companies, the capacity of global distributed energy storage systems may increase by 10 times and up to approximately 2400 MW by 2018.

    The report also pointed out that influenced by the rapid development of battery technologies, the distributed energy storage market will also see rapid growth in recent years. Meanwhile, the popularization of PV, EV, EV charging stations, and household energy networks will generate new demands for distributed energy storage systems.

    It is expected that by 2024, the capacity of global distributed energy storage market may increase to 12,000 MW. However, to achieve this objective, researchers must overcome difficulties on cost control, software development, control system design, and integration technology optimization.

Industrial Energy Storage Solution of Small-Sized Monolithic Tubular Gel Battery

• The industrial energy storage solution, developed by the Technology Center of Sacred Sun, is specially designed for the new energy storage systems of small scale industrial consumers, business customers and private household customers. In most cases, the system is cycling at uncontrollable PSOC state. After partial discharging, batteries may experience a fully recharge, but this fully charging state happens once in a blue moon in such kind of systems. The major advantage of this system is that it could keep running at PSOC state in a long period.

  6V&12V OPzV tubular gel batteries (conform to DIN standard) are applied in this system.

  Compact and modularized system design has largely facilitated the installation and maintenance of the system.

  Currently, Sacred Sun is the only Chinese lead acid battery manufacturer who can manufacture all 2V, 6V, and 12V OPzV tubular gel batteries, so it stands for the most advanced level of tubular gel batteries in China.

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.

What’s the classification of battery?

In accordance with electrolyte, batteries can be divided into: alkaline battery, acid battery, neutral battery and organic electrolyte battery.

In accordance with working principle and storage mode, batteries can be divided into primary battery and secondary (storage) battery.

In accordance with positive and negative electrode materials, batteries can be divided into Zinc series battery, Nickel series battery, Lead series battery, Lithium series battery, Manganese dioxide series battery, and Air (oxygen) series battery.
