磷酸铁(tie)锂电池(chi)是一(yi)种液体锂离(li)子(zi)电池(chi),一(yi)般(ban)用于(yu)新能源汽车或(huo)公共汽车的动(dong)力电池(chi),其基本(ben)参数(shu)如下(xia):
1、容量5.5A;
2、单体(ti)能量密(mi)度≥120Wh /kg;
3、3C充放(fang)电300次可(ke)保持容量96%以上;
4、内(nei)电(dian)阻小(xiao)于等于8欧(ou)姆;
5、每月自放电≤2%。
磷(lin)酸铁锂(li)电(dian)池(chi)安(an)(an)全技(ji)术-通气防(fang)爆(bao)管原理:在(zai)电(dian)池(chi)内部发生化(hua)学反应的条件下(xia),电(dian)池(chi)内部产生的气体会先聚集在(zai)通风管中,有利于(yu)电(dian)池(chi)内部气体的扩散,电(dian)池(chi)不会爆(bao)炸。锂(li)电(dian)池(chi)引入通风管装置,有效解(jie)决了电(dian)池(chi)在(zai)过充、短路(lu)、碰撞(zhuang)等极(ji)端条件下(xia)温度过高造成的安(an)(an)全问题。
磷酸(suan)铁(tie)锂电池(chi)(chi)性能提(ti)升专利技(ji)术-端面焊(han):放弃极(ji)耳(er)结构,采(cai)用毛坯(pi)(pi)涂覆工艺(yi)制(zhi)作单个金属毛坯(pi)(pi)电池(chi)(chi),再采(cai)用端面焊(han)工艺(yi)。采(cai)用端面焊(han)接技(ji)术可以(yi)大大降低电池(chi)(chi)的内阻(zu)和温(wen)升,提(ti)高电池(chi)(chi)的循环寿命,实现电池(chi)(chi)的快速充电和释(shi)放。

对(dui)于很多不做电(dian)(dian)(dian)(dian)池的朋友来说(shuo),他们不知道梯(ti)(ti)次电(dian)(dian)(dian)(dian)池的应用(yong)是什(shen)么。事(shi)实(shi)上,梯(ti)(ti)次电(dian)(dian)(dian)(dian)池是指电(dian)(dian)(dian)(dian)池的使用(yong)退化,针对(dui)的是电(dian)(dian)(dian)(dian)池组。即新电(dian)(dian)(dian)(dian)池组在(zai)使用(yong)一定时间后(hou)已经衰减(jian),不足(zu)以满足(zu)当(dang)前设备(bei)的供电(dian)(dian)(dian)(dian)要求。但是,电(dian)(dian)(dian)(dian)池没有坏。经过(guo)一定的维修和调(diao)整(zheng)后(hou),可(ke)以在(zai)具有一级(ji)较(jiao)低功耗要求的设
随着科技水平的(de)不(bu)断提高,铝(lv)(lv)壳电(dian)池(chi)在生活中(zhong)(zhong)的(de)应用越来越广泛。为(wei)了让电(dian)池(chi)内(nei)部(bu)(bu)材(cai)料在使用过程(cheng)(cheng)中(zhong)(zhong)不(bu)受到损坏,一般(ban)都会在电(dian)池(chi)外部(bu)(bu)包裹一层保(bao)护(hu)壳。铝(lv)(lv)壳电(dian)池(chi),顾名思义(yi),铝(lv)(lv)壳是电(dian)池(chi)的(de)重(zhong)要(yao)保(bao)护(hu)壳。面对如此重(zhong)要(yao)的(de)保(bao)护(hu)壳,在选(xuan)(xuan)择过程(cheng)(cheng)中(zhong)(zhong)千万不(bu)能马虎,那么要(yao)怎(zen)么选(xuan)(xuan)择铝(lv)(lv)壳电(dian)池(chi)呢
特斯(si)(si)拉(Tesla Inc., TSLA)掌门人马斯(si)(si)克(ke)(Elon Musk)所(suo)推崇的(de)一种成本(ben)不那么高(gao)昂的(de)电池技术(shu)去(qu)年在(zai)全球大(da)汽车(che)市场中(zhong)(zhong)国(guo)(guo)占据(ju)了主(zhu)导地位,这表明特斯(si)(si)拉的(de)美(mei)国(guo)(guo)和欧洲竞争对手面(mian)临挑(tiao)战。中(zhong)(zhong)国(guo)(guo)官方数(shu)据(ju)显(xian)示,2021年,使用磷酸铁(tie)锂(LFP)技
锂电(dian)(dian)池(chi)与镍氢(qing)电(dian)(dian)池(chi)相比哪(na)个(ge)(ge)更(geng)好,首先(xian)要看(kan)两者用于哪(na)类产品,其次要比较两者的(de)经济效益,这样才能更(geng)好的(de)知道锂电(dian)(dian)池(chi)和镍氢(qing)金属电(dian)(dian)池(chi)哪(na)个(ge)(ge)好。一、镍氢(qing)电(dian)(dian)池(chi)的(de)优(you)缺点(dian)1、镍氢(qing)电(dian)(dian)池(chi)的(de)优(you)点(dian):(1)能量密度高(gao),是(shi)镍镉(ge)的(de)1.5倍;(2)电(dian)(dian)压1.2V-1.3V,相当于镍镉(ge)电(dian)(dian)池(chi);
