Positive electrode active material particles according to the present invention each having a layered rock salt structure and being represented by compositional formula (LiGammaXe)(NiaCobXcZd)O2 (in the formula, X represents a divalent metallic element optionally substituted with a Li site, Z's represent metallic elements at least including Al and / or Mn but excluding X, and 0.93<=Gamma<=1.15, 0.82<=a<=1.00, 0<=b<=0.12, 0.001<=c+e<=0.040, 0<=d<=0.10, and a+b+c+d=1 are satisfied) help maintain battery capacity at a sufficient level, and exhibit high cycle characteristics and excellent thermal stability.

Disclosed is a lens-fitted photographic film unit containing a roll of unexposed photographic film. The lens-fitted photo film unit uses a specific battery of a different size or shape from conventional standardized batteries. A hollow protrusion is formed in a battery holding room. A hollow of the hollow protrusion joins with a dark room for the photographic film. If the hollow protrusion is cut away with the intention to put a conventional battery in the battery holding room, the light-tightness of the dark room is destroyed. When a cartridge chamber bottom lid is opened to remove a film cartridge, an interconnection lever transmits the opening movement of the lid to a sliding plate. Then the sliding plate turns a charge switch of a flash circuit ON, and locks the charge switch in the ON position.

The invention discloses an energy storage equipment voltage balance method. When the voltage difference of single power sources in a series connection (power sources) energy storage equipment reaches a set value, high-voltage single power sources and a flying supercapacitor are in parallel connection to charge the flying supercapacitor, after the flying supercapacitor is charged to a positive voltage or the voltage of one high-voltage single power source is changed to be the lowest, the flying supercapacitor is switched to the next highest-voltage power source and is in parallel connection with the highest-voltage power source, and so repeatedly, voltage balance of energy storage equipment is achieved. The invention further discloses a voltage balance system using the method. According to the energy storage equipment voltage balance method and system, the single supercapacitor is used as a flying element to be in parallel connection with the single power sources in the opposite direction, the problem that traditional voltage differences are too small is solved, the demand for large-power charging and discharging is met, sufficient capacity can further be provided, and energy transfer efficiency is improved. Circuits are simple, and each single power source is used as a working power source for controlling a switching transistor. The single power sources are used for being in parallel connection with the supercapacitor in a reversed polarity mode, and the response speed and the reliability of the system are improved.

The invention relates to a rapid internalization process of a tubular colloidal battery, comprising the steps of: first, preparing two electrolytes with different densities; The second step is to pourthe low density electrolyte into the battery and charge the battery at a low current of 1-2h; 3, charging and discharging in four stage, and replacing that low-density electrolyte with the high-density electrolyte in the second charging process of the second stage. As that unique internalize forming process is adopted, the difficulty of the internalizing forming is reduce, the internalizing forming efficiency is improved, and the electric energy consumed by the internalize forming is saved at the same time.

The invention discloses a wholly-plastic pressure-bearing double-circulation solar water tank which comprises a water tank housing and an inner water tank arranged in the water tank housing. A heat preservation layer is arranged between the water tank housing and the inner water tank, and the inner water tank is further provided with a pressure relief port communicated with the outside. The wholly-plastic pressure-bearing double-circulation solar water tank is characterized inn that the inner water tank consists of an upper seal head, a lower seal head and a middle housing, a heat exchange pipe bundle is installed in the inner water tank through a positioning plate, the internal spaces of the upper seal head, the lower seal head and the heat exchange pipe bundle serves as pipe passes, and the portion between the heat exchange pipe bundle and the middle housing serves as a housing pass. The wholly-plastic pressure-bearing double-circulation solar water tank is mainly made of a high-polymer material or a modified high-polymer material or a reinforced high-polymer material, is high in strength, resistant to corrosion and capable of saving a large amount of metal materials, the manufacturing cost of a solar water heater system can be remarkably reduced, and the wholly-plastic pressure-bearing double-circulation solar water tank has the advantages of being long in service life, high in reliability, simple in production process and the like, can be industrially produced in a large-scale mode and has wide market prospect.

The invention relates to a clean EGR loop system. The system comprises a charge coagulating chamber (1), a catcher (2), an EGR cooler (3) and an EGR valve (4); the charge coagulating chamber (1) is of a cavity structure, a metal strip (12) serving as a discharge electrode is arranged on the charge coagulating chamber (1), an electrode plate (23) is arranged in the catcher (2), an outlet of the charge coagulating chamber (1) is connected with an inlet of the catcher (2), an outlet of the catcher (2) is connected with an inlet of the EGR cooler, and the EGR valve is arranged on an outlet of the EGR cooler; compared with the prior art, the system has the beneficial effects that through the electric field effect, the content of NOx and HC in automobile engine waste gas can be reduced, the content of NOx and HC is reduced, corrosion to the EGR cooler and the EGR valve is reduced, and final emissions of the NOx are reduced; the system is low in cost, small in size, high in efficiency, small in resistance and easy to regenerate; the system can be additionally arranged in a GDI engine without complex modification, the service life of the EGR valve and the EGR cooler is greatly prolonged, and the response speed and the circulation efficiency of EGR are improved.
