Mokhoa oa ho boloka betri ea ion ea phosphate le hoja litšenyehelo tsa lisebelisoa tsa ho boloka matla a lithium ion li feta habeli betri ea lead-acid, sena ha se mohloli oa pele oa lithium ion tse setseng. Libaka tse fapaneng tsa ts&39;ebeliso li fapane le litlhoko tsa matla a tlhahiso le bophahamo ba theknoloji ea polokelo ea matla, &39;me polokelo e fapaneng ea matla ke sepheo se lakatsehang. Ka la 18 Phupu, setsi sa pele sa naha sa heso sa 100,000 sa li-kilowatt tse tjhajang matla a betri se phatlalalitsoeng Toropong ea Zhenjiang, Profinseng ea Jiangsu, se ile sa bula likhokahano tse ncha bakeng sa mochini le ts&39;ebetso ea liteishene tse kholo le tse mahareng tse tjhajoang matla a betri.

Libetri tsa lithium-ion li qapiloe halofong ea bobeli ea lilemo tsa bo-1990, joalo ka tse ling tse ngata tse qapiloeng, betri ena e ka nchafatsoang e bile betere ho feta lilemo tse peli. Lintho tsena tsa lik&39;hemik&39;hale li tsitsitse haholo, empa ka kakaretso, ho hanyetsa ka hare ho kholo haholo, motho e mong le e mong o sebelisa mokotla oa graphite o hloekileng le lisebelisoa tse ling tsa lik&39;hemik&39;hale tse sebetsang hantle ho fokotsa ho hanyetsa ka hare. Betri ena ea ho tjhaja e na le melemo e mengata, &39;me melemo e mengata ea puisano e se nang mohala ke ho tjhaja le ho ntša motlakase o sebetsang o tsitsitse haholoanyane.

Betri e tloaelehileng ea ho tjhaja e phalla holimo, ka ts&39;ebetso eohle ea ho tjhaja le ho tsoa, ​​matla a sebetsang a fokotseha butle-butle. Matla a sebetsang a betri ea lithium phosphate ion ha a fetohe. Molemo ke ofe? Boleng bo phahameng ba ho futhumatsa ba betri ea Li-Li ke betri ea 350c-li mochesong o phahameng, ke LI-MnO2 le Liicoo2 feela tse holimo le tlase ho 200C.

Bophara ba mocheso o sebetsang (-20c-75c), boleng bo phahameng ka ho fetisisa ba mocheso oa betri ea lithium phosphate ion ke 350c-500c, lithium manganese le lithium cobalt oxide feela 200C. Sebaka se seholo, boima ba betri e tjhajang leseli hangata e qosoa inthaneteng, molumo o potlakile ho feta matla a potoloho e khuts&39;oane (ke hore, mohopolo). Joalo ka Ni-H, betri ea Ni-CD e na le memori, mme betri ea lithium phosphate rechargeable ha e eo, ho sa tsotelehe hore na betri e hokae, e ka sebelisoa ho tjhaja, ha e hloke ho tjhaja betri.

Boholo bo ts&39;oanang ba matla a betri ea lithium phosphate ion ke 2/3 ea matla a betri ea lead-acid, &39;me boima ba letlooa ke 1/3 ea betri ea lead-acid. Ntlafatsa bophelo ba betri ea lead-acid e fokotsehile ho isa makhetlo a 300, boleng bo phahameng ke makhetlo a 500, athe betri ea lithium phosphate matla a lithium-ion, bophelo ba potoloho bo fihla ho feta makhetlo a 2,000, tjhaja e tloaelehileng (sekhahla sa lihora tse 5), e ka theoleloa makhetlo a 2000. .
