锂电(dian)池由正极、负(fu)极、电(dian)解液和(he)隔膜四个主要部分组成。
1. 正极(ji):正极(ji)是电池的活性物质,通(tong)常(chang)由(you)锂金(jin)属(shu)氧化物或锂合金(jin)构成,其主要功(gong)能是提供电流。
2. 负极:负极是(shi)电(dian)(dian)池的储存活性物质(zhi),通常由碳材料构(gou)成,其主要功(gong)能是(shi)吸收电(dian)(dian)池的化学反应,将电(dian)(dian)子从(cong)正极传递(di)到(dao)负极。
3. 电(dian)解液:电(dian)解液是电(dian)池中用来产生电(dian)流的(de)化学物(wu)质,通常由锂盐和有机溶剂组成(cheng)。
4. 隔膜:隔膜是电池(chi)的隔板(ban),防止电池(chi)内部短路,同时(shi)起(qi)到保(bao)护电池(chi)和电解液的作用。
锂电(dian)(dian)池(chi)的(de)(de)正极(ji)和(he)(he)负极(ji)之间(jian)的(de)(de)电(dian)(dian)压是电(dian)(dian)池(chi)的(de)(de)电(dian)(dian)压,而电(dian)(dian)解液(ye)的(de)(de)电(dian)(dian)流(liu)是电(dian)(dian)池(chi)产生(sheng)电(dian)(dian)流(liu)的(de)(de)关键(jian)。隔膜的(de)(de)作(zuo)用也是防止电(dian)(dian)池(chi)内部(bu)短路,同时(shi)保护(hu)电(dian)(dian)池(chi)和(he)(he)电(dian)(dian)解液(ye)。
磷(lin)酸铁锂电(dian)(dian)(dian)池的其(qi)他要(yao)求(1) 电(dian)(dian)(dian)池表面应清(qing)洁(jie),不(bu)生锈,无(wu)(wu)划痕,不(bu)变(bian)形和机械损坏,无(wu)(wu)泄漏现象,不(bu)腐(fu)蚀接(jie)口触点;(2) 电(dian)(dian)(dian)池表面应具有(you)必要(yao)的产(chan)品标(biao)(biao)(biao)识,并注明(ming)生产(chan)日期(qi),产(chan)品标(biao)(biao)(biao)识,印(yin)刷清(qing)晰,标(biao)(biao)(biao)识清(qing)晰,不(bu)易脱落(luo);(3) 电(dian)(dian)(dian)池的正(zheng)负(fu)极端子和极性应标(biao)(biao)(biao)记清(qing)楚,表面有(you)
近日,中国铁塔(ta)发布2021-2022年磷酸铁锂换电电池产(chan)品招标(biao),招标(biao)的预估规模为(wei)(wei)80万组(zu),折(zhe)合为(wei)(wei)1036.8MWh。中标(biao)人数量(liang)为(wei)(wei)4个,依(yi)次(ci)对应份额为(wei)(wei)40%、25%、20%和15%。其中电池组(zu)、无线传输模块、无线天线、电源接口不(bu)含(han)税(shui)高投标(biao)限价为(wei)(wei)1.2
磷(lin)酸铁锂电(dian)(dian)池(chi)包和电(dian)(dian)池(chi)组(zu)怎样串并联使(shi)用?磷(lin)酸铁锂电(dian)(dian)池(chi)包串并联有(you)哪些注(zhu)意事项?山木新能(neng)源MOTTCELL作为国(guo)内(nei)较大的知名厂商,不仅(jin)仅(jin)在电(dian)(dian)芯(xin)(xin)生产研发(fa)上(shang)有(you)着独特的优势,而且拥有(you)自己(ji)的PACk组(zu)装车间,从而保(bao)证了从电(dian)(dian)芯(xin)(xin)生产到。电(dian)(dian)池(chi)组(zu)制造全程品质工(gong)艺管控(kong)。统一(yi)
锂(li)电(dian)(dian)(dian)池参数不一(yi)(yi)致(zhi)主要是指容量、内阻(zu)和开路电(dian)(dian)(dian)压的(de)(de)(de)不一(yi)(yi)致(zhi)。如果(guo)锂(li)电(dian)(dian)(dian)池的(de)(de)(de)电(dian)(dian)(dian)芯(xin)(xin)不一(yi)(yi)致(zhi),则(ze)会出现以下问(wen)题(ti):1、容量损耗。锂(li)电(dian)(dian)(dian)池的(de)(de)(de)电(dian)(dian)(dian)芯(xin)(xin)单体(ti)组(zu)(zu)成(cheng)电(dian)(dian)(dian)池组(zu)(zu),容量符合 “木桶(tong)原理”。差的(de)(de)(de)电(dian)(dian)(dian)芯(xin)(xin)的(de)(de)(de)容量决定了整个锂(li)电(dian)(dian)(dian)池组(zu)(zu)的(de)(de)(de)容量。2、使用寿(shou)命(ming)损失(shi)。同样(yang),锂(li)电(dian)(dian)(dian)池组(zu)(zu)的(de)(de)(de)寿(shou)命(ming)由寿(shou)命(ming)
回望新(xin)能源(yuan)发(fa)展(zhan)历程(cheng),其中(zhong)(zhong)中(zhong)(zhong)日(ri)韩为主导地位,牢牢占(zhan)据着市(shi)场份额以及技术壁垒,由于这几年能源(yuan)危机以及低(di)碳环境要求(qiu),新(xin)能源(yuan)迎(ying)来(lai)新(xin)的发(fa)展(zhan)机遇(yu),相当(dang)于新(xin)的工业(ye)革命(ming)。美国在(zai)电(dian)池领域处于落(luo)后的第二梯队,为了(le)摆脱对电(dian)池进口的依(yi)赖(lai)。同时在(zai)新(xin)时代发(fa)展(zhan)中(zhong)(zhong)掌握话语权。以福
虽然锂(li)(li)电(dian)(dian)(dian)池是(shi)当下受(shou)欢(huan)迎的(de)(de)电(dian)(dian)(dian)池,但随(sui)着技术的(de)(de)发展(zhan),锂(li)(li)电(dian)(dian)(dian)池也被(bei)归类为(wei)多种类型,每种类型各有优(you)缺(que)点(dian),但总(zong)的(de)(de)来说(shuo),锂(li)(li)电(dian)(dian)(dian)池有以下几种常见(jian)的(de)(de)优(you)缺(que)点(dian):1、锂(li)(li)电(dian)(dian)(dian)池的(de)(de)优(you)点(dian)(1) 高电(dian)(dian)(dian)压(ya)(ya): 单体(ti)电(dian)(dian)(dian)池的(de)(de)工作电(dian)(dian)(dian)压(ya)(ya)高达3.7-3.8V (电(dian)(dian)(dian)池电(dian)(dian)(dian)压(ya)(ya)可(ke)充(chong)电(dian)(dian)(dian)至4.2V),是(shi)Ni-
