锂电池产品工艺介绍

艾博尔研发部2015年7月锂电池分类锂金属原电池与锂离子电池区别锂电池反应机理图示锂金属原电池结构与性能工艺流程说明相关认证目录锂电池定义：是一类由锂金属或锂合金为正负极材料，使用非水电解质溶液的电池。锂电池大致可分为两类：锂金属原电池：含有金属态的锂，将化学能转换为电能，化学反应不可逆转，不可充电。一般使用二氧化锰作为正极材料，金属锂为负极材料，使用非水电解质溶液的电池总反应：Li+MnO2=LiMnO2锂离子电池：不含有金属态的锂，并且是可以充电的。一般使用锂合金金属氧化物为正极材料（如磷酸铁锂/钴酸锂/锰酸锂等），石墨为负极材料，使用非水电解质的电池总反应：LiCoO2+6C=Li(1-x)CoO2+LixC6充放电反应机理为锂离子在正负极材料之间的嵌入和脱嵌锂电池分类锂离子电池具有以下优点：电压高，单体电池的工作电压高达3.6-3.9V，是Ni-Cd、Ni-H电池的3倍比能量大，目前能达到的实际比能量为100-145mAh/g（2倍于Ni-Cd，1.5倍于Ni-MH）循环寿命长,一般均可达到500次以上,甚至1000次以上.安全性能好,无公害,无记忆效应可快速充放电，1C充电是容量可以达到标称容量的80%以上。工作温度范围高，工作温度为-25~55°C。锂离子电池也存在着一定的缺点，如：电池成本较高。主要表现在正极材料LiCoO2的价格高（Co的资源较少），电解质体系提纯困难。大电流放电困难。由于有机电解质体系等原因，电池内阻相对其他类电池大。故要求较小的放电电流密度，一般放电电流在0.5C以下，适合于中小电流的电器使用。需要保护线路控制。锂电池分类锂金属原电池具有以下优点：比能量较锂离子电池高，比能量达200-400mAh/g，单体工作电压2.8-3.2V或3.2-3.4v，性能稳定，自放电小，可大电流放电贮存寿命长，室温下可以贮存10年以上使用温度范围广，一般为-20~60度和-55~85°C高安全性，高可靠性，放电电压平稳，无公害锂二氧化锰是比较常用的一款锂金属原电池，其正极活性物质二氧化锰采用电解二氧化锰，是锂电池正极活性物质中比较价廉的一种，可以大量推广使用。锂电池分类锂电池分类种类锂金属原电池锂离子电池锂錳电池锂亚电池钴酸锂磷酸铁锂电压（V）3v3.6v3.7v3.3v比能量（mAh/g）200400140100自放电率/年<2%<1%循环500~1000次循环800~2000次保存时间5-10年10-15年3-5年，但3个月需进行充放电7-8年，但3个月需进行充放电适用温度-20~60度-55~85度充电0~55度放电-20~60度充电0~55度放电-20~60度放电电流中小小大脉冲放电强弱弱强价格中中非常高高应用领域安防，RFID,电子产品智能仪表，军用，汽车电子小型便携电子设备电源大型电动车，电动工具，UPS及应急灯MechanismforreactionofLi-ionBattery以钴酸锂正极材料为例，反应如下：充电时:正极LiCoO2→Li(1-X)CoO2+XLi++Xe-；负极6C+XLi++Xe-→LixC6放电时:正极Li(1-X)CoO2+XLi++Xe-→LiCoO2；负极LixC6→6C+XLi++Xe-总反应:LiCoO2+6C→Li(1-x)CoO2+LiXC6MechanismforreactionofLi-MnO2BatteryOpencircuitLiMnO2CurrentCollectorAnodeCathodeSeparator/electolyteClosedcircuitLiMnO2CurrentCollectorAnodeCathodeSeparator/electolyte负极反应:Li→Li++e正极反应:MnO2+Li++e→MnO2(Li+)总反应:Li+MnO2→MnO2(Li+)Li+e-solidelectrolyteinterfaceCRbatteryKeyfeature①Hidischargeplatform:Above2.0whenusing②Lowself-discharge：yearlyself-dischare<2%（RT).③PassedUL
