  • The balance of rechargeable batteries

    Both necessary and sufficient manner by the current set-voltage charge of the implementation of phase II trial showed that this charging method of charging more efficient, commonly used for domestic and foreign. The current charge for the end-voltage balance criterion, in theory, is consistent with the understanding that the activity should be based on positive and negative electrode material to judge the extent of the transformation. With the anode board is the conversion of the active substance, the charge current will be gradually reduced, but even if the board is negative electrode active material into after the completion of all, in theory, the charge current is still not zero, but at a lower value On the basic stabilizing. The calculation, the stable value of about 0.42mA/Ah. So, when the charge current of 1 mA / Ah ~ 2mA/Ah, and 2 ~ 3h stability in the same time, the end of that charge. At this point, charging devices are derived from the automatic shift to the state Fuchong state. In the event one of the following cases, the need for a balanced battery (additional) charge:

    1, when the battery Fuchong operation between the team found that the battery voltage exceeds the standard deviation;

    2, the exchange lost power when the time exceeds the value (such as 3 ~ 5min above) or discharge capacity exceeds the value (5% ~ 10% C10 above;

    3, when Fu Chong continued operation of three to six months and check test after discharge.

    Valve regulated sealed batteries, whether it is depleted of glass fiber or gel-cell battery, the electrolyte in a state of absorption or colloidal state, no free electrolyte. Therefore, the battery on the body, both high and low pressure in charge, can only charge impact on the length of time.

    Tests showed that in a depth of discharge, with the same charge current, respectively, with 2.28 V, 2.30V, 2.35V, 2.40V are charging pressure charging, fully charged for the difference in time not more than three to five hours. Therefore, the valve-regulated battery charging voltage of a balanced proposal for 2.30 (+ 0.05) (- 0.02) V / months

  • IMEC to develop full-printed solar cells for photovoltaic conversion efficiency of 3%

    IMEC is an independent research institution located in Belgium (Belgium) of Leuven (Leuven), in the nano-electronics and nano-technology leadership position in the world, and also the Netherlands, the United States, China and Japan to set up an office, with more than 1,600 employees, including the Mill and Visiting Fellow, in 2007 brought revenue for the country about 2.4 billion euros. They are mainly resolved on the basis of academic science and industrial manufacturing process differences between the unique processes, systems technology, the patent group and the most advanced equipment. Today, they verify that the entire solution process of the organic solar cells.
    “We are developing a way for the whole solution process of the organic solar cell can be high-quality electric sexual contact, so this battery has a 3% of the electricity conversion efficiency.” IMEC said so. Research laboratories in Belgium and the use of previously developed the initiative for organic solar cells sprayed layer coating technology, “This method is suitable for mass production of volume after volume (roll-to-roll) manufacturing process, so whether it is or can be hard Flexible substrates can be, fast and cheap manufacturing large-area organic solar cells. ”
    Metal electrodes formed in the organic layer on top of semi-review body, electric contact must be allowed between conductivity between 104 and 106S/cm, and has high stability, has been through the commercialization of nano-particles of silver ink, under nitrogen at the use of spray gun spray painted, and then by 100 ~ 180 ℃ sintering, so that molten particles to form a continuous film. IMEC refers to “advanced technology throughout the ink-jet printing can be printed or manner of the realization of large area, and with volume on the volume of equipment to complete production.” Solution in order to complete the whole process of organic solar cells, IMEC put forward a reverse structure, that is, before the formation of electron collection layer (cathode), then is the semiconductor layer, and then coated with the anode. “If the cathode in the semiconductor layer after the formation of the electron layer resistance files must be in active layer above can avoid the type of metal electrode into the process of damage caused.”
    The whole solution process, the barrier layer (usually the use of zinc oxide, ZnO, or titanium dioxide, TiO) formation, brought about by surface morphology, resulting in subsequent phases of silver nanoparticles to penetrate, resulting in cell conversion efficiency decreased. The anode in this area, due to electric-hole barrier layer (commonly used poly -3,4 - dioxo-thiophene ethylene [poly (3,4-ethylenedioxy-thiophene)], poly styrene sulfonic acid [poly (styrenesulfonate)] or both mixed-doped [PEDOT: PSS]) have adequate thickness, formed in the organic layer can protect the damage that may occur. Anode and then sprayed on the silver particles on, can be the whole solution process of the organic solar cells. All the organic materials such as poly (3 - f alkyl thiophene [poly (3-hexyl thiophene), referred to as P3HT] and 6,6 - phenyl-methyl-C61 D [(6,6)-phenyl C61-butyric acid methyl ester, referred to as PCBM) can be dissolved in solution and deposited on indium-tin oxide glass substrate.
    Components of the photoelectric conversion efficiency is about 3%, equivalent to the general use of components made of evaporation, but the short-circuit current is higher than 10mA/cm2, when the nano-particle sintering temperature dropped to below 150 ℃, then can use flexible substrates, including polyethylene naphthalate [polyethylene naphthalate, referred to as PEN

  • Pay close attention to choose green durable battery

    Listen to MP3, Walkman, flashlight batteries and ultimately, support. Recently, the National Quality Supervision Department at the national level on the battery on the market for a sampling, results showed that sampling rate of 74.5 percent qualified. Students as possible to buy buy brand batteries.

    It is understood that the total samples, including Guangdong, Zhejiang, Shanghai, Sichuan, Chongqing, Jiangsu and other provinces and cities in six of the 29 enterprises producing 55 kinds of products. The main quality problem: the discharge capacity does not meet the standards. This characteristic of the use of battery time is short, there are probably a result of the use of electrical leakage and damage. Followed by the performance of battery leakage resistance failed. Battery leakage resistance is a measure of 367759-001 performance over the case of discharge if there will be damage to electrical outlet fluid indicators. Manganese dioxide batteries are acidic liquid leakage, the leakage of alkaline zinc manganese dioxide batteries are strongly alkaline liquid.
