The electrochemical reactions are involved in the cell the. The principle of chemical reaction of lead-acid battery is as follows
Negative reaction: Pb+HSO4- PbSO4+H++2e
Positive reaction: PbO2+2e+HSO4-+3H+ PbSO4+2H2O
Electrode reaction: PbO 2 +2 +2HSO +Pb 2Pb SO 4- 4 H 2 H+ 2 O (+2)
State of charge discharge state from the reaction principle can be seen in the discharge, the anode material is generated with lead sulfate sulfuric acid in the electrolyte, so called Double sulfation reaction". Under normal circumstances, the lead sulfate generated by the structure of osteoporosis, and its crystal is very small, very high electrochemical activity, spongy lead sulfate and lead this very high activity can be re generated positive in charge under the current two lead oxide and cathode. Through this stable reversible process, the battery can store the electric energy and release the electric energy. Experienced users are aware that the cost of the battery is the largest consumption of electric bicycles, so users are very concerned about the extension of battery life. First of all, it is necessary to assume that the charger is not a problem, the user is the right to use the battery life is critical.
The use of a certain period of Hangzhou forklift battery, in order to avoid subsequent use of vulcanized etc., lead sulfate in a period of time after the formation of higher activity, if in this period of time is not timely charging or charging fully, so it is not timely into positive and negative active material of lead sulfate will be in low temperature again re crystallization, precipitation in crystalline lead sulfate, so again and again, makes the crystal grain increasing, conductive performance is poor, difficult to be dissolved, charging is difficult to restore the lead sulfate crystals, namely irreversible salt (mentioned in this manual refer to such salt salt). There are many reasons for battery failure, such as the deadly grid electrode corrosion and electrode grid serious deformation, loss of electrode active material, battery internal short circuit or open circuit and other physical and chemical reasons, but the statistics show that the failure of the vast majority of batteries are caused by irreversible sulfation of the electrode active material. This papersummed in charge to recover two of lead oxide and spongy lead, with great harm to the battery: it is a consumption of active substances, effective capacity of the battery is reduced, so long will lead to battery scrap; not only itself when charging is difficult to restore, and void clogging of the porous electrode, prevent the electrolyte through increased resistance; charge and discharge heat more, increasing the cell temperature will increase the plate corrosion and deformation of the active substance to lead off the cell structural scrapped; the charge efficiency is decreased, the charging time is prolonged, and the energy waste caused by time;
In the electrolysis of water phenomenon is more serious, because the battery is easy to dehydration dry up; capacity decline, output power shortage, in order to maintain a certain output can only increase the depth of discharge, will cause more severe sulfation, forming a vicious spiral; due to consumption of sulfuric acid, resulting in decreased electrolyte density, reduce the large current discharge capacity, performance decline. Including the battery in the process of using the main reasons of the formation of irreversible sulfation: depth of discharge and discharge current, no charge in time or lack of charge; battery battery performance is not the same, there are differences over large capacity performance behind the battery; for a battery group was significantly lower than other batteries, causing the the battery voltage drops, when charging the battery due to backward first to be full of other batteries still need to charge and discharge the charge form, because the first behind the battery is empty, so as to form a discharge, resulting in sulfation further intensified, the backward degree is more serious, forming a vicious spiral. fork
负极反应:Pb+HSO4- PbSO4+H++2e正极反应:PbO2+2e+HSO4-+3H+ PbSO4+2H2O电极反应:PbO 2 +2 H+ +2HSO 4- +Pb 2Pb 2 SO 4 +2 H 2 O充电状态 放电状态从上述反应原理可以看到,在放电时,正负极材料都与电解液中的硫酸反应生成硫酸铅,所以叫"双硫酸盐化反应"。在正常情况下,所生成的硫酸铅结构疏松,并且其晶体非常细小,电化学活性很高,这种活性很高的硫酸铅在充电时可以在电流作用下重新生成正极的二氧化铅和负极的海绵状铅。通过这种稳定的可逆过程,电池实现了储存电能和释放电能的作用。有经验的用户都知道电池的费用是电动自行车*大的消耗,所以用户非常关心延长电池的使用寿命的问题。首先要假定充电器没有问题,用户是否正确使用对电池的寿命至关重要。使用一定期限的杭州叉车电瓶,为避免后续使用出现硫化等情况,硫酸铅在形成之后一段时间内活性较高,如果在这一段时间内没有及时充电或者充电不完全,使它未及时转化为正负极活性物质,硫酸铅则会在温度低时再重新结晶,在结晶质硫酸铅上析出,这样一次又一次地重复,使结晶颗粒不断增大,成为导电性能差、难以溶解、充电时难以恢复的硫酸铅结晶,即通常所说的不可逆盐化(本手册所称的盐化均指此类盐化)。电池失效的原因有多种,如致命的电极板栅腐蚀、电极板栅的严重变形、电极活性物质的脱落、电池内部短路或断路等理化原因,但是,统计表明,绝大多数电池的失效都是由电极活性物质的不可逆硫酸盐化造成的。这种盐化物在充电时难以恢复为二氧化铅及海绵状铅,对电池具有很大的危害:它的形成消耗了活性物质,使电池的有效容量降低,长期如此将导致电池报废;不仅它本身在充电时难以恢复,而且会阻塞多孔电极的空隙,妨碍电解液通过,增加内阻;充放电时发热更多,电池温度升高,会加大极板的腐蚀与变形,使活性物质脱落导致电池的结构性报废;使充电效率下降,充电时间延长,造成时间及能源的浪费;导致更严重的电解水现象,电池容易失水干涸;由于容量下降,输出功率不足,为保持一定的输出就只能加大放电深度,会造成硫酸盐化更加严重,形成恶性循环;由于消耗了硫酸,导致电解液密度下降,大电流放电能力降低,性能下降。电池使用过程中形成不可逆硫酸盐化的主要原因包括:经常性的深度放电及过放电,没有及时充电或充电不足;电池组中电池性能不一致,存在差异过大的落后电池;表现为电池组中某一个电池的容量明显低于其它电池,造成整个电池组电压下降,充电时落后电池因*先被充满而其余电池仍需充电而形成过充电,放电时该落后电池又因*先被放空从而形成过放电,从而导致硫酸盐化进一步加剧,使得落后程度更加严重,形成恶性循环。叉车蓄电池作为货值比较高的产品,其购买价格与使用价值若不成比例,造成的损失十分大,使用年限决定它的附加值。一组1.5吨叉车配国产叉车蓄电池品牌价格在1.4-1.6万之间,在2年左右单体将频繁出现故障,超过产品保修时间,维修的电瓶单体价格很高,纵然能搞好,后续依然出现单只容量不均衡,既耽误了工作又消耗了金钱。蓄电池是电叉车牵引力的来源,其成本占叉车价格的10%~15%,是电叉车*重要的部件。 www.berens-china.com杭州叉车蓄电池组 -
