鋰離子電池具有能量密度高、循環壽命長、開路電壓高及污染小等優點，已用于小電流放電的移動通訊、筆記本和數碼相機等領域，但高倍率放電性能有待提高，那提高高倍率鋰電池放電性能的方法有哪些呢？

1、鋰電(dian)池結(jie)構對高倍率放(fang)電(dian)的影(ying)響

電(dian)(dian)池(chi)(chi)(chi)在(zai)高倍率放電(dian)(dian)時(shi)，由于極(ji)化，電(dian)(dian)壓急劇(ju)下降，需要盡量降低電(dian)(dian)池(chi)(chi)(chi)的(de)(de)內阻。可在(zai)電(dian)(dian)極(ji)極(ji)片上(shang)焊接多(duo)只(zhi)極(ji)耳(er)，降低電(dian)(dian)池(chi)(chi)(chi)的(de)(de)內阻，使電(dian)(dian)流密度(du)增大(da)，電(dian)(dian)荷傳遞速度(du)加快(kuai)；但在(zai)實際操作過程中(zhong)，正負極(ji)基體(ti)易受損，影(ying)響大(da)電(dian)(dian)流放電(dian)(dian)的(de)(de)效果。

2、鋰電(dian)池(chi)正(zheng)極活性物(wu)質(zhi)與(yu)導(dao)電(dian)劑、粘結劑的(de)配比對大電(dian)流放電(dian)的(de)影響(xiang)

電(dian)池(chi)(chi)在(zai)大(da)電(dian)流放(fang)電(dian)時，內阻極化明顯，電(dian)壓急(ji)劇下降，因此要通過增(zeng)加導(dao)電(dian)劑來提高正負極的(de)導(dao)電(dian)性，以(yi)減小極化電(dian)壓；同時電(dian)池(chi)(chi)在(zai)大(da)電(dian)流放(fang)電(dian)時，會出現發熱現象，正負極活性物質有可能在(zai)循(xun)環(huan)過程(cheng)中發生脫落。為了(le)保證電(dian)池(chi)(chi)的(de)正常工(gong)作(zuo)電(dian)壓和理想的(de)循(xun)環(huan)壽(shou)命，需要合理地(di)搭配活性物質、導(dao)電(dian)劑和粘結劑。

3、極板(ban)面密度、壓實(shi)密度的影響

鋰電(dian)(dian)(dian)(dian)(dian)池(chi)正負極(ji)板的(de)(de)(de)面(mian)(mian)密(mi)(mi)(mi)度(du)、壓(ya)(ya)實(shi)密(mi)(mi)(mi)度(du)對電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)性(xing)能有(you)很(hen)大(da)(da)(da)的(de)(de)(de)影響(xiang)。極(ji)板的(de)(de)(de)面(mian)(mian)密(mi)(mi)(mi)度(du)、壓(ya)(ya)實(shi)密(mi)(mi)(mi)度(du)過(guo)大(da)(da)(da)，雖(sui)然有(you)利于提(ti)高電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)能量(liang)密(mi)(mi)(mi)度(du)，但(dan)(dan)是電(dian)(dian)(dian)(dian)(dian)解液(ye)很(hen)難(nan)滲透到(dao)極(ji)板內(nei)部，造(zao)成電(dian)(dian)(dian)(dian)(dian)池(chi)濃差極(ji)化(hua)和(he)內(nei)阻增(zeng)大(da)(da)(da)，而且過(guo)于致(zhi)密(mi)(mi)(mi)的(de)(de)(de)活性(xing)物質(zhi)在循環過(guo)程中，會由于電(dian)(dian)(dian)(dian)(dian)解液(ye)的(de)(de)(de)逐(zhu)漸滲入(ru)，發生(sheng)溶脹，導(dao)致(zhi)脫落，造(zao)成電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)(de)下降(jiang)；極(ji)板的(de)(de)(de)面(mian)(mian)密(mi)(mi)(mi)度(du)、壓(ya)(ya)實(shi)密(mi)(mi)(mi)度(du)太小，雖(sui)然有(you)利于電(dian)(dian)(dian)(dian)(dian)解液(ye)的(de)(de)(de)滲透和(he)減少電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)濃差極(ji)化(hua)，并提(ti)高電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)性(xing)能，但(dan)(dan)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)能量(liang)密(mi)(mi)(mi)度(du)偏低。需(xu)要合(he)理地設計極(ji)板的(de)(de)(de)面(mian)(mian)密(mi)(mi)(mi)度(du)、壓(ya)(ya)實(shi)密(mi)(mi)(mi)度(du)，在保證大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)(de)前提(ti)下，最大(da)(da)(da)限度(du)地提(ti)高電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)能量(liang)密(mi)(mi)(mi)度(du)。

提高(gao)高(gao)倍率(lv)鋰電(dian)池放(fang)電(dian)性(xing)(xing)能(neng)的(de)方法可以(yi)通過改變電(dian)池卷(juan)芯的(de)結構，從內(nei)部降(jiang)低了(le)電(dian)池的(de)內(nei)阻，在此(ci)基礎上，通過調整活性(xing)(xing)物質(zhi)與導電(dian)劑的(de)配比(bi)，改善了(le)放(fang)電(dian)平臺；通過調整極板的(de)面密度和壓實(shi)密度，提高(gao)了(le)大電(dian)流放(fang)電(dian)性(xing)(xing)能(neng)。
