?? Zhoukou Leoch DJM batteries offer - Jiyuan Yuasa Battery NP prices - Henan Panasonic Battery LC-P distributor Dear users: due to the current market is too confusing, in order to protect your rights we recommend that you choose a regular business, formal agents, choose the regular website to order Yuasa Battery Products! Or with my phone in advance to confirm, in order to avoid unnecessary losses to you! Simple introduced: the battery capacity and utilization of the plates is mainly related to the active substance. The active substance of battery plates are: lead dioxide, lead electrochemical reaction in a chemical reaction inside the battery in the process, its essence is the active substance and dilute sulfuric acid electrolyte plates occurred, resulting in the current. In this electrochemical reaction, often accompanied by a study called "sulfation" negative reaction, that is, lead and sulfuric acid to generate a lead, the lead sulfate which is an insulator, it is bound to form produce very bad impact on the battery charge and discharge, since the formation of sulphate in the negative plate, the greater the internal resistance of the battery, the battery can charge and discharge performance worse, can not absorb the positive and negative plate gas produced, Over time battery failure. White said that the greater is the battery internal resistance of the battery discharge obstruction will be greater, resulting in insufficient release of capacity. Further factors influencing the capacity of lead-acid batteries are many: discharge rate, temperature, termination voltage, plate geometry, the internal resistance of the battery electrolyte concentration: ohmic resistance and polarization resistance ohmic resistance: the electrode material, electrolyte, separator The resistance polarization resistance: resistance of both positive and negative chemical reaction caused when not directly affected, but by affecting other aspects affecting each other. In other words, there is no direct relationship between the two, but by influencing each other's constraints to influence each other. For example: a change in temperature can affect the battery electrolyte and the resistance change. 1) electrolyte temperature, the diffusion rate increases, resistance decreases, the electromotive force increases, and so the battery capacity utilization of the active material increases with temperature 2) electrolyte temperature reduction is great, viscosity increases, ion movement blocked, diffusion capacity decreased resistance increases, an electrochemical reaction resistance increases, resulting in decreased battery capacity. Lead-acid batteries short circuit and cause of lead-acid battery lead-acid battery internal short circuit means connected to the positive and negative groups. Lead-acid batteries short circuit mainly in the following aspects: (1) open-circuit voltage is low, closed-circuit voltage (discharge) quickly reaches the termination voltage. (2) large current discharge, the terminal voltage rapidly drops to zero. (3) open, the electrolyte density is very low, at low temperatures the electrolyte will appear icing. (4) charging, the voltage rises very slowly, always remains low (sometimes zero). (5) During charging, the electrolyte temperature rises very rapidly. (6) charging, electrolyte density to rise very slowly or hardly changed. (7) does not take charge or take gas bubbles appear late. The main causes of internal short lead-acid batteries in the following areas: poor (1) partition quality or defect, so that through the electrode active material, resulting in positive and negative plates virtual contact or direct contact. (2) partition channeling bits resulting positive and negative plates are connected. (3) expansion of the plates active material shedding, shedding due to excessive deposition of the active substance, resulting in positive and negative plate edge or side of the lower edge of the sediment caused by contact with each other is connected to the positive and negative plates. Cause within (4) conductive objects fall into the battery positive and negative plates are connected. When the formation (5) welding electrode group "Lead flow" is not divisible, the "lead beans" between positive and negative plates in the presence or assembly, in the course of charging and discharging caused by positive and negative plate is connected to the separator damage.
