Sacred Sun Will Hold the Fourth National Lead Acid Battery New Technology Symposium

Lead acid battery industry is an important part of the new energy industry. For a long time, lead acid batteries are widely used in starting power, motive power, emergency backup and energy storage and provide a reliable guarantee for the national economy, national defense and people's lives. Lead acid battery industry has become an essential foundation of national economy and sustainable development of society; it plays a key role in national economic construction.

In recent years, the lead acid battery industry in China is phasing out backward production capacity through the implementation of environmental remediation and regulations on one hand. On the other hand, Inner conditions also improved such as constantly improving the level of equipment, environmental protection and occupational health security conditions, and technological progress and new technologies industrialization, all of these have greatly narrowed the gap with developed countries.

In order to further promote the research and industrialization of new products and new technology in lead acid battery and achieve scientific and sustainable development of the whole industry chain. Sacred Sun (Shandong Sacred Sun Power Sources Co., ltd.) will hold the Fourth National Lead Acid Battery New Technology Seminar in Qufu, Jining of Shandong Province from October 15 to 17, 2016.

The main contents of this symposium include: the implementation of lead acid battery industry standards, new technology for lead carbon batteries and carbon fiber grid battery, new materials for lead carbon battery, new-type long-life grid alloy, research and industrialization of new technology for waste lead-acid battery.

Up to now, Sacred Sun FCP lead carbon deep cycle battery with super long life based on Furukawa technology could operate 4200 cycles at 70% depth of discharge (DOD). Provided that one day one cycle, battery service life could up to 10 years, reduce the cost per kW h of energy storage to 0.08 Dollar (0.5RMB). In view of this, Sacred Sun’s FCP lead carbon batteries have successfully applied in many large-scale energy storage projects in domestic and overseas on accounts of its advanced energy storage technology.

Dr Fanna, director of New Technology Research Dept. of Sacred Sun R&D Center, will bring the latest pure lead battery technology and deliver a speech entitled “Current situation and performance study of the pure lead battery” in the conference.

In the conference, Johnson, YUASA, Hoppecke, East Penn, Furukawa and other well-known international companies will take part in the Lead acid battery conference and they will make a special report; Sailing, China Shoto, Tianneng, Chaowei, Camels and other domestic backbone enterprises will introduce new technology of lead-acid battery in recent years in the conference; The experts of university scientific research institutes, such as Harbin Institute of Technology and Chemical Warfare Research Institute, will introduce the recent research achievements related to new technologies and new materials in the conference. The leaders of the relevant state departments will be invited to the conference, it will be a platform for local government departments to understand the lead acid battery industry, promote sustainable development of the industry, and create a harmonious and relaxed environment.

Qufu: Japanese Experts Come to Sacred Sun to Help Its Product Upgrading

 Qilu News (May 11, 2015):  To speed up the upgrading project of Sacred Sun’s high-energy, environment-friendly and long-life lead carbon batteries (energy storage battery), Japanese experts of Furukawa were invited to Sacred Sun to offer technical training and guidance recently.

  The experts have explained advanced manufacturing technologies and crafts of the battery as while as management philosophy and patterns of lean production through training seminars and site instructions.

    On the one hand, Sacred Sun has obtained advanced research, manufacture and management concepts in battery industry, which could facilitate it to improve its products’ technology content and core competitiveness; on the other hand, Sacred Sun has further extended its talent supply-demand chain, which has made great contributions to its talent cultivation and team building.

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.

  

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.

Technical Characteristics of Pure Lead Battery

• In pure lead batteries, the positive and negative grids are made of pure metallic lead, without any grid alloys. To solve casting problems of pure lead and improve the mechanical strength of pure lead grid, special technologies and equipments are needed in manufacturing.

  Major technical characteristics of pure lead batteries are as follows:

  （1）Pure lead ingots are first made into lead belts, then stamped into grids.

  （2）Crystal lattices of pure lead grids are extremely compact, and therefore largely improve the corrosion resistance of grids.

  （3）Super-thin plates are adopted in pure lead batteries.

  （4）Except metallic lead, all other high purity materials have adopted high purity materials.

  （5）The manufacturing of pure lead battery is controlled by fully automatic robots.
