该构造使电池外表积大，呈片状，构造简单，因而良好的散热性，并允许自由的设计电池形状，以适应在加载电池装入车辆。做到了汽车应用中良好性价比。三、AESC的主要产品AESC的主要产品为：electricvehicles(EV)锂电池和hybridelectricvehicles(HEV)由于电动汽车和混合动力汽车对电池的要求不同，这两种锂电池在材料、构造和性能上各不一样。EV电动汽车电池设计为高容量型电池，这样可以实现单次充电后续航能力。而HEV混合动力汽车那么被设计为高输出型电池这样可以提高瞬间传输电力。1.AESC高容量锂电池〔支持快速充电〕由于电动汽车仅由5车载电池提供能量，必须具有大容量电池，实现大续航能力；另外，当出行时，必须具有快速充电能力。AESC锂电池可实现30Ah或更高的电池容量，这是普通手机锂电池的10～30倍。该类电动汽车锂电池主要有以下3中型号：(1)高能电池单元Lithium-ioncell:Highenergycell具有高散热和高能量密度的特点，其阴极和电极分层layeringcathodesandelectrodes，形状为290mm×216mm，构造紧凑，容量大。混合了锂镍氧化物的锂锰阴极使电池的稳定性好，寿命长，并且由于电池的层叠构造使电池的外表积大，散热性能好。..〔2〕模块：高能量模块Module:Highenergymodule该模块具有紧凑的形状，增加了装载在车辆上的效率。通过4个锂电池单元通过2并联，2串联装在金属盒中制成，这样既可以防止锂电池单元振动，又可以灵活的包装为简单紧凑的形状。该模块在日产尼桑和其他汽车中广泛采用〔3〕高能量电池组Pack:Highenergybatterypack该电池组可以实现为车辆量身定制设计通过连接多个模块的传感器，控制器，以及其他元件，然后容纳单元中的自定义设计用于每个车型。由48个电池模块连接成的电池组已在日产尼桑和theRenaultKangoo上使用，具有360V的输出电压和24kWh的容量，可供一个标准家庭2天使用。具体构造如下：Voltage,temperature,andsuchareconstantlymonitoredbysensorsattachedtothemodulesinthepack.ThedataissentfromthebatterycontrollertothevehiclecontrolunitviaaCAN(ControllerAreaNetwork).Whenavehicleismaintenancedataservicefactory,thecircuitisinterruptedbyoperatingtheSDSW(ServiceDisconnectSwitch)sothatworkcanbesafelyperformed.2.AESC混合动力汽车用高输出锂电池混合动力电动汽车〔HEV〕是由发动机和电动机的组合供能。当车辆第一次启动或其他时间需要一个大的转矩移动时，需要电动机和发动机共同驱动；而在其他时间，驱动能量被回收并用于对电池进展充电。因此，该电池特别注重电池的瞬加输出电能的能力。AESC生产的HEV锂电池具有构造紧凑，重量轻，并且可提供远超其他公司锂电池的高输出能力。主要有以下三种型号：〔1〕高能电池单元Lithium-ioncell:Highenergycell该单元高散热和高功率密度的特点，形状为290mm×216mm，由层叠阴极，电极和别离器包装在一起组成。由于采用了层叠构造，该单元散热性能好。阴极由锂镍氧化物掺入锂锰材料组成，阳极材料采用无定形碳。〔2〕高能模块Module:Highenergymodule该模块具有紧凑的形状，增加了装载在车辆上的效率,由8个HEV单元连接后装在金属盒中组成，可以防止HEV单元受振，又可以灵活的包装为简单紧凑的形状〔3〕高能量电池组Pack:Highenergybatterypack该电池组可以实现为车辆量身定制设计，通过连接多个模块的传感器，控制器，以及其他元件，然后容纳单元中的自定义设计用于每个车型的情况下形成的。由12个HEV模块连接组成的电池组已在NissanFugaHybridandtheNissanCIMA上使用，具有1.4kWh的容量和346V的输出电压。为四、技术支持AESCinheritedtheresultsofR&DconductedbybothNissanandtheNECGroupandhasreachedthestageofrealworldapplicationswithourbatteriesnowbeingusedinmassproductionvehicles.Withtheseresults,wehaveestablishedafoundationofmassproductioncapabilitiesandproductsthatexhibitnotonlycostperformancebutalsoperformanceandqualitythatarebackedbythesafetyperformancethatisessentialforautomotiveapplications.Withthisfoundation,AESCwillcontinuetoendeavortoprovideadvancedlithium-ionbatteryproductstoawiderangeofcustomersaroundtheworld.1.采用理想的锰系阴极材料(AESC'sManganeseSpinelCathodeMaterial)与其他阴极材料的锂电池比照，锰系锂电池平安性好，性价比更高。(1)ManganeseSpinelStructurethatisStableEvenwithOverchargingWhenlithium-ionbatteriesarecharged,lithiumionsmovefromthecathodematerialtotheanodematerial.Becauselithiummanganateisaspinelstructurewiththemanganeseinalatticeshape,thematerialremainsstableevenwhencharging.(2)Manganese,amaterialwithabundantreservesandastablylowprice.ManganesehasbeeanimportantmaterialinAESC'slithium-ionbatteries,andparedtonickelandcobalt,whichareclassifiedasraremetals,abundantreservesofmanganesehavebeenconfirmed.Therefore,manganeseisinexpensive,andthepriceremainsstable.2.采用层叠构造形式，实现了散热好，重量轻，构造紧凑的特点。AESC'scellisasheetshapedcellthatissealedbyalaminatefilm.Becauseofthebroadsurfacearea,thecellsdemonstrateexcellentheatdissipation,andbecauseoftheirsimple,pactstructure,thecellsprovideahighdegreeofdesignfreedomtoacmodateloadingthebatteriesintoavehicle.AESC'slithium-ionbatteries(cells)forbothEVandHEVapplicationsfeatureastructureinwhichcathodesandanodesarealternatelystackedwithaseparatorsandwichedbetweenandthensealedwithalaminatefilm.
