原厂科电蓄电池放电电压

　近年来，铅酸蓄电池技能不断开展，产品日臻老练。起动电池结构逐步优化升级，免保护蓄电池广泛运用、仍然是军用、民用交通运输配备的重要电源设备，为我国成为世界首要轿车出产国起到重要支撑效果。阀控电池、胶体电池等作为备用电源、大型储备电源的核心部件，其出产已成为国民经济开展中重要的基础性工业。铅酸蓄电池职业大有可为。

　　铅酸蓄电池的首要原料——铅可收回反复运用，只要出台废旧电池收回的相关工业方针，正确引导商场，就能够有用处理我国有色金属短缺、铅污染等资源、环境许多问题。因此，正确认识蓄电池职业现状、掌握开展趋势、有用处理其本身存在的问题，是循环运用资源、建造节约型社会，是向国民经济科学开展有用途径。

　　我国铅酸蓄电池工业现状

　　自加入WTO后，跟着国家相关工业的拉动及世界电池出产厂商在华投资的增多，我国铅酸蓄电池工业开展较快，年增加速度超过30%以上。一起跟着世界商场需求的不断增加，我国也成为了世界上最大的铅酸蓄电池出口国之一。我国铅酸蓄电池技能与世界水平距离不明显，轿车电池处于世界先进水平，动力用、电动自行车用电池技能接近世界先进水平。

　　通过20多年的开展，免保护和密封蓄电池技能进步取得了巨大成就，使铅酸蓄电池不仅在交通运输、军事国防等传统领域得到广泛应用，并且被广泛应用与太阳能光伏发电、风力发电、通信电源、电力变配电系统、铁路、船舶通讯、起动、照明电源、UPS电源中。技能进步推动了蓄电池职业的快速开展，使其成为新式的朝阳工业之一。可是因为铅酸蓄电池首要原材料——铅的价格在2004年下半年大幅度增加，并持续保持高价位运行，铅酸蓄电池的职业赢利呈下降趋势。

In recent years, with the change of market demand, the production mode and technology of lead-acid batteries have been continuously improved, and the manufacturing level has been continuously improved. The specific energy, cycle life, functional consistency, safety and environmental protection of lead-acid batteries have been continuously improved. With the development of power supply such as electric bicycle batteries, high temperature curing technology develops rapidly. It is generally believed that high temperature curing can improve the life of batteries. In recent years, negative additives and their proportions have accumulated a large amount of gesep.com parameters, and some regular experiences have been found. Other advanced skills such as winding batteries, bipolar batteries and thin plates are still in the research stage in China, and there is no mass production.
From the situation of patent skill declaration in China, the defense line of battery profession in recent years is battery structure improvement and battery model development. Foreign patent skills mainly touch on cash thin-plate bipolar lead batteries, sealed batteries with modular structure and colloidal electrolyte lead batteries. Therefore, our patent skills are still far away from those of other countries.
Present Situation and Problems of Environmental Protection in Lead-acid Battery Industry

Through years of construction and development, the lead-acid battery profession in China has fundamentally constituted a system and developed rapidly, and environmental protection issues have also made breakthroughs. At present, the treatment methods and skills of lead smoke, lead dust, sulfuric acid mist and water in China have been basically sophisticated. Major and medium-sized lead-acid battery manufacturers continue to intensify technical transformation efforts, update process equipment, and select rings all over the country. High efficiency filter barrel type dust collector replaces electrostatic precipitator, wet type dust collector is selected to purify lead smoke, turbulent sphere type acid fog purifying tower is selected to absorb sulfuric acid fog, flocculation reaction treatment of lead-containing acid wastewater can eliminate or reduce the impact of pollutants on the environment from the technical point of view. The production environment is constantly improved. Most large and medium-sized production enterprises have achieved clean production, and some of them have achieved clean production. It has passed the national environmental system certification.

　　处理环保问题的关键行动是全面实施电池收回方针

　　我国正在活跃推广循环经济，废旧蓄电池的90%可以收回运用，可是我国工业方针没有给废旧电池收回一个良好的开展空间，致使其成为长期困扰我国蓄电池开展的瓶颈。我国没有一部废旧铅酸蓄电池收回管理的法定规范，全国未建立一家专业性废旧铅酸蓄电池收回公司，无一家专业再生铅企业或蓄电池企业建立了全国性收回网络和地区性收回网络，整个收回工作处于涣散运营的无序状况，废铅酸蓄电池的收回率不高。铅收回的问题出现在不规范企业之中，整顿与加强管理势在必行，国家有关部分应尽快出台方针，像撤销小煤窑、小锻炼相同，撤销小的废旧铅收回企业。一起出台方针鼓励、扶持大型蓄电池出产厂家进行废旧电池收回运用。限制我国再生铅职业开展要素首要有：，环保设备本钱负担重。企业技能先进、环保设备齐全的企业运营效益敌不过技能落后、污染严峻的乡镇“小炼铅”。第二，监管力度不够。没有运营许可证也在进行再生铅出产，治理整顿治标不治本，一度关闭的“小炼铅”风声一过，死灰复燃。第三，工业方针不利于正规企业的开展。赋税过重也削弱了大型再生铅企业加大环保治理的才能。
