US GNB Battery S512 / 100AH ??US GNB batteries with the following characteristics: 1, aspiration technology: GNB glass sponge absorbing liquid electrolyte does not flow technology to make, use microporous, low internal resistance and elasticity of glass wool, so that the battery in vivo gas line with> 99%; 2, safety valve: the valve opening pressure GNB large batteries are 6psi (41.3kpa), and small and medium sized battery is 3psi, is among the highest grade, open pressure frequency low, reduce water loss, battery body keep pressure on 3-6psi, at this highest pressure gas recombination efficiency; 3, polypropylene shell: Polypropylene water gas leakage rate than polyvinyl chloride (PVC) and ABS / SAN plastic low four times more water Loss minimize parts; 4, tetravalent salt formation: The temperature and humidity for a long time into the plate, crystal plate active material after formation of large and high hardness, it is not easy to fall off, the battery will be more durable, crystals of larger channel formed between the rapid penetration of active materials to make sulfuric acid, the electrolyte can penetrate into the internal structure of the pastel, enhancing discharge characteristics and charge-discharge cycle performance; 5, when assembled into: GNB used is assembled into a method, first plates assembled into battery after charging into the electrolyte filling, then independent testing of each single battery voltage and capacity, this method reduces the number of manpower into contact with the plate, the plate was destroyed reduce pollution and oxidation of opportunity; 6, to prevent leakage measures: GNB use - housing and cover welding, arc welding plates, "weight" filling electrolyte leakage measured argon gas, and other measures; MFX alloy anode plate: Compared with the general lead-calcium alloy, GNB charging gases produced when a relatively small amount, after a very deep discharge recovery is good, charge and discharge cycles up to 1250 times, particularly strong corrosion resistance; high-G6, NB battery cooling efficiency: GNB within the battery cells into steel, the cooling efficiency can be over time and aging 16 times higher than plastic human body, and thought given to human life but they can stay young, and the sun and the moon with the deposit of portable electronic products to the battery as a power source. With the rapid development of portable products, increase the amount of various batteries, and developed many new batteries. In addition to all the more familiar with the high-performance alkaline batteries, rechargeable nickel-cadmium batteries, nickel metal hydride batteries, lithium batteries also developed in recent years. This paper describes the basic knowledge about lithium batteries. This includes its properties, the main parameters, meaning models, application and use precautions. Lithium is a metallic element, its chemical symbol Li (the English called lithium), is a silvery white, very soft, and chemical properties of active metal, is the lightest metal. It applies in addition to the atomic energy industry, but can produce special alloys, special glass (for use on the TV screen glass) and lithium batteries. It is used in lithium battery anode. Lithium battery also divided into two categories: non-rechargeable and rechargeable types. Non-rechargeable batteries called disposable batteries, it can only be a one-time conversion of chemical energy to electrical energy, power can not be reduced back to chemical energy (or restore poor performance). The rechargeable battery is called secondary batteries (also called accumulator). It can convert electrical energy into chemical energy stored, in use, and then convert chemical energy into electrical energy, which is reversible, as the main features of electrical energy to chemical energy lithium battery: smart portable electronic products requiring small size, light weight, but the battery size and weight compared with other electronic components is often the biggest and heaviest. For example, I remember when the "Big Brother" is very "thick, heavy," while today's cell phone is so lightweight. Wherein the improvement is the battery played an important role: the past is the nickel-cadmium batteries, lithium-ion batteries now. Lithium biggest feature is the high specific energy. What is the ratio of energy? Refers to the ratio of the energy per unit weight or unit volume of energy. Specific energy Wh / kg or Wh / L to represent. Wh is a unit of energy, W is watts, h is the hour; kg is kilogram (weight units), L is liters (volume units). Here we give an example to illustrate: 5 nickel-cadmium battery is rated at 1.2V, with a capacity of 800mAh, then the energy of 0.96Wh (1.2V × 0.8Ah). 5, the same size lithium - manganese dioxide battery rated at 3V, its capacity is 1200mAh, then its energy 3.6Wh. Both cell volume is the same, the lithium - manganese dioxide battery specific energy is 3.75 times that of nickel-cadmium batteries a 5 nickel-cadmium battery weighs about 23g, and a lithium 5th! - Manganese dioxide battery It weighs about 18g. A lithium - manganese dioxide battery 3V, and two nickel-cadmium batteries only 2.4V. Therefore, when the number of batteries using lithium small (portable electronic products reduced volume, weight), and long service life of the battery. In addition, the lithium battery has a discharge voltage stability, wide operating temperature range, low self-discharge, long storage life, no memory effect and pollution-free advantages. Disadvantage of lithium is expensive, so it is not yet widely used, mainly used in handheld computers, PDA, communication equipment, cameras, satellites, missiles, torpedoes and other equipment. With increasing development of technology, process improvement and production of lithium prices will continue to decline, the application will be more common. Non-rechargeable lithium non-rechargeable lithium batteries have many currently used lithium - manganese dioxide batteries, lithium - thionyl chloride batteries, and lithium batteries and other compounds. Before the article explains the two most commonly used. 1 Li? - Manganese dioxide battery (? Li MnO2) Lithium - manganese dioxide battery is a lithium anode, manganese dioxide as the cathode, and the organic electrolyte disposable batteries. The main features of this battery is the battery voltage, rated voltage (which is 2 times the normal alkaline batteries) 3V; termination of the discharge voltage of 2V; than the energy (see example above); discharge voltage stable; there are better The storage properties (storage time more than 3 years), self-discharge rate (annual self-discharge rate ≤2%); Operating temperature range -20 ℃ ~ + 60 ℃. The battery can be made into different shapes to suit different requirements, it has a rectangular, cylindrical and button shape (button). Cylindrical and have different diameters height dimension. 2 Lithium -? Thionyl chloride batteries (? Li SOCl2) Lithium - thionyl chloride battery is the highest energy density of a current up to 500Wh / kg or 1000Wh / L level. Its rated voltage is 3? 6V, to discharge at medium current extremely flat 3? 4V discharge (it can be discharged in the capacity range of 90% to keep small change). Battery can operate within a range of -40 ℃ ~ + 85 ℃, but the capacity at -40 ℃ ambient temperature at about 50% capacity. Self-discharge rate (annual self-discharge rate ≤1%), the storage life of more than 10 years. Application Notes both lithium disposable batteries, non-rechargeable (danger when charging!); Not a short circuit between the battery positive and negative; not too large current discharge (more than the maximum discharge current); the battery to terminate When the discharge voltage electronic products should be promptly removed; spent batteries can not squeeze, incineration and demolition; not exceed the specified temperature range. As the lithium battery's voltage is higher than ordinary batteries or nickel-cadmium batteries, make no mistake so as not to damage the circuit use. Through the familiar model of the CR, ER can know its type and rated voltage. When buying new batteries, be sure to buy the original model, otherwise it will affect the performance of electronic products.
