Default nike air max 1 Impact of the traditional lead-acid

Use of lead-acid batteries in three areas: floating use; deep discharge applications; part of the discharge status purposes. ,网络聊天中看出对方的性格
traditional lead-acid batteries (flooded) in life are usually subject to one or more of the following reasons because of:
1, expansion of the positive plate, positive plate First, the expansion of the plane in the direction of the plate (if the grid is due to the growth of the corrosion layer and elongation); the other is in the vertical direction of plate expansion (through the expansion of its active substances). Repeatedly charging and discharging will cause the expansion of the cathode active material. Because the discharge reaction volume of solid product PBSO4 much larger volume than the reactants PBO2. Restore the battery to recharge most of the PBO2, but can not return to the original volume; the contrary, there is no expansion of anode plate and a tendency, perhaps because the PB is more soft than PBO2, so with the larger volume into PBSO4, negative active material more likely to be compressed. As the cycle of continuous positive plate active material caused by the continuous expansion of fragmentation, so that the active material and current collector, electrical contact between the poor.
2, water loss during charging in the past generation of hydrogen and oxygen, the volume of electrolyte will be reduced to a number of active substances can not be in contact with the liquid level. This process will be automatically accelerated, because the electrolyte drying and increased battery internal resistance,塔罗牌----我的前世与今生,nike sb shoes, which in turn makes a lot of heat generated during charging, then the faster the evaporation water loss. Battery gassing battery has also been significant effect of impurities.
3, acid stratification,nike air max 1, the battery re-charging, and in the plate in sulfuric acid between the plates, and the thicker the acid (relative density greater) tend to sink at the bottom of the battery. Concentration of sulfuric acid changes in the vertical direction will cause the uneven use of active substances,christian louboutin big kiss flats, so by the formation of irreversible PBSO4 shorten the battery life.
4, charging less, if the two electrodes, an electrode often in an arbitrary state of charge less, or not charging method because of the use, or because the electrode potential can not reach sufficient enough, then it may be The rapid decline in battery capacity.
5, corrosion, corrosion of positive grid vulnerable. The decline of the speed of the process of grid composition,asics gel netburner, alloy microstructure, board-level potential,shoes jimmy choo, electrolyte composition and temperature. Resistance of the corrosion products are usually higher than the grid, thus reducing the battery power output. In extreme cases, corrosion can cause fracture and the plate grid collapse.
failure mode most of the batteries in the traditional lead-acid batteries, through the following methods are fiction, and can accept:
1, positive plate expansion using the PB-SB ALLOY enhanced positive plate creep strength of the gate, which delayed the positive plate in the plane direction of elongation. For the flat positive plate design, the direction perpendicular to the plate on the expansion of cluster groups can make to reduce pressure. Tube has to firmly maintain the positive plate active material of the casing, which reduces the swelling, loss of contact and a tendency to fall off.
2, water loss,gt 2140 asics 高血压单方-后果:永远断根,家里有高, through the process of adding water to water loss problem can be solved.
3, acid stratification, acid concentration gradient can be extended over charge, intended to stir gassing the battery acid to eliminate.
4, charging less, in some state of charge for use of the battery (such as power supply in remote areas and the batteries used in hybrid electric vehicle), the need for regular fully charged to maintain battery capacity.
With these types of measures, for various uses flooded the actual battery life can be greatly improved. However, the need to reduce water maintenance, to avoid the use of sour gas escape and the trend has become more convenient, which makes the
