磷(lin)酸(suan)铁(tie)锂(li)铝壳(qiao)电池(chi)的优势有哪些(xie)?
1、重(zhong)量轻:同(tong)一规格容量的(de)磷酸(suan)铁锂(li)铝壳(qiao)电(dian)池(chi)(chi)的(de)体积(ji)是铅(qian)酸(suan)电(dian)池(chi)(chi)的(de)2/3,重(zhong)量是铅(qian)酸(suan)电(dian)池(chi)(chi)的(de)1/3。
2、高温(wen)性能好:磷(lin)酸铁锂铝壳电池电峰值(zhi)高达350℃-500℃,工(gong)作温(wen)度范围广。
3、大容量(liang):充(chong)电(dian)电(dian)池在充(chong)满不放(fang)完电(dian)的条件下工作时,其容量(liang)会迅速下降(jiang)到额定容量(liang)以下,这种现象称(cheng)为记忆效应。镍氢(qing)电(dian)池和镍镉电(dian)池有记忆功(gong)能,而(er)磷酸铁锂铝壳电(dian)池并无记忆功(gong)能,随(sui)用随(sui)充(chong)。
4、安全性(xing)(xing)能好:磷酸铁锂(li)晶体中的(de)P-0键稳定且不(bu)易分解(jie),即使在高温或过充的(de)情况下也不(bu)会生成强氧(yang)化性(xing)(xing)物质,具(ju)有良好的(de)安全性(xing)(xing)。
5、使(shi)(shi)用(yong)寿(shou)(shou)命(ming)长(zhang):磷酸(suan)铁(tie)锂(li)铝(lv)壳(qiao)电(dian)(dian)(dian)池(chi)是指以(yi)(yi)磷酸(suan)铁(tie)锂(li)为(wei)正极(ji)材(cai)料(liao)的(de)锂(li)离子电(dian)(dian)(dian)池(chi)。铅酸(suan)电(dian)(dian)(dian)池(chi)的(de)使(shi)(shi)用(yong)寿(shou)(shou)命(ming)一般在(zai)300次,高(gao)可达(da)500次,磷酸(suan)铁(tie)锂(li)铝(lv)壳(qiao)电(dian)(dian)(dian)池(chi)的(de)使(shi)(shi)用(yong)寿(shou)(shou)命(ming)可达(da)2000次以(yi)(yi)上,标(biao)准充电(dian)(dian)(dian)(5小时率)可达(da)2000次。铅酸(suan)电(dian)(dian)(dian)池(chi)的(de)使(shi)(shi)用(yong)时间为(wei)1 ~ 1.5年,而磷酸(suan)铁(tie)锂(li)电(dian)(dian)(dian)池(chi)在(zai)相同(tong)条(tiao)件下,理论寿(shou)(shou)命(ming)将(jiang)达(da)到7 ~ 8年。综合考虑,性价比是铅酸(suan)电(dian)(dian)(dian)池(chi)的(de)4倍以(yi)(yi)上。
6、环保:磷酸铁锂铝壳电(dian)(dian)池一般认为(wei)不含任何(he)重金属和稀有金属(镍氢电(dian)(dian)池需(xu)要稀有金属),无毒(du)(通过SCS认证),无污染,符合欧(ou)洲RoHS法(fa)规(gui),为(wei)绝对(dui)绿(lv)色电(dian)(dian)池证书(shu)。
磷酸铁锂铝壳(qiao)电池也有缺点,具体如下:
其低(di)温性(xing)能(neng)差,正性(xing)材料振动密度很小(xiao),其体积要比钴酸锂电(dian)池(chi)(chi)要大(da),在(zai)微型电(dian)池(chi)(chi)方面不占优势(shi)。当用(yong)于动力电(dian)池(chi)(chi)时,磷酸铁锂铝壳(qiao)电(dian)池(chi)(chi)还面临着电(dian)池(chi)(chi)一致(zhi)性(xing)问题。
