Lithium ion bhatiri purojekiti kumashure

  Lithium-ion battery is an indispensable energy storage product that drives human modern life, Lithium ion batteries are indispensable for daily communication, energy storage, household appliances, electric vehicles, electric ships, etc. And in special applications such as military, deep sea, and mining, lithium-ion batteries are characterized by their high energy density, long service life, and superior safety performance, Widely replaced the traditional lead-acid batteries, nickel-metal hydride batteries and other previous generation products.

Lithium-ion mabhatiri iindasitiri-inoda tekinoroji,Kukudziridzwa kweindastiri iyi kunogonawo kufambisa kusimudzira kwekugadzirwa kwemidziyo yenyika uye maindasitiri ezvekushandisa. Yepamberi membrane tekinoroji, otomatiki musangano mutsara tekinoroji, yakaderera dova uye yakakwirira yakachena yemhepo tekinoroji uye inoenderana michina inoshandiswa mukati meiyo lithium ion bhatiri kugadzira, Iyo ine nhungamiro yakanaka uye yekuratidzira basa rekuvandudza mamwe matekinoroji eindasitiri nemidziyo. Zvishandiso zvinoshandiswa mumabhatiri e lithium-ion zvinogona kusanganiswa nemhangura yemuno, cobalt ore uye graphite ore yekudzika kwakadzika mu Ultra-yakaonda mhangura foil ye lithium-ion mabhatiri, lithium cobaltate (lithium nickel cobalt manganate) cathode zvinhu, uye yakakwirira- simba graphite anode zvinhu.

Kunyange zvazvo mabhatiri e-lithium-ion ari iye zvino ari rudzi rwakakurumbira rwebhatiri, nekuvandudzwa kwekombiyuta, kune marudzi akawanda emabhatiri e-lithium-ion, rimwe nerimwe rine zvaro zvakanakira uye zvisingabatsiri. Nekudaro, zvakazara, mabhatiri e-lithium-ion ane zvinotevera zvakanakira zvakanakira uye zvisingabatsiri:

1. Zvakanakira zve lithium-ion mabhatiri.

(1) High voltage: Mhepo inoshanda yebhatiri rimwe chete inogona kusvika kusvika pa 3.7-3.8V (yakakwirira sero voltage inogona kubhadharwa kusvika ku4.2V), iyo inopeta katatu iyo yeNi Cd uye Ni-H mabhatiri.

(2) Simba repamusoro rakananga: Parizvino, simba chairo rinogona kuwanikwa rinenge 555Wh/kg, zvinoreva kuti zvinhu zvinogona kusvika kune imwe nzvimbo inodarika 150mAh/g (3-4 times Ni Cd, 2-3). nguva Ni MH), iri padyo ne88% yehukoshi hwayo hwekufungidzira.

(3) Hupenyu hurefu hwekutenderera: kazhinji hunogona kusvika kanopfuura ka500, kana kutopfuura ka1000, uye lithium iron phosphate inogona kusvika kanopfuura ka2000. Upenyu hwemabhatiri mumidziyo yakaderera yezvino inoburitsa inopeta kaviri kukwikwidza kwavo.

(4) Kuita kwakanaka kwekuchengetedza: kusvibiswa-isina, hapana mhedzisiro yekurangarira. Sezvo yakatangira Li-ion, mabhatiri e-lithium-ion akadzikisa nzvimbo dzawo dzekushandisa nekuda kwekuumbwa kwe dendrites uye mapfupi maseketi anokonzerwa nesimbi lithium. Li-ion haina zvinhu zvinosvibisa nharaunda zvakaita secadmium, lead, uye mercury. Chinhu chikuru chekudzosera kumashure kwemamwe mabhatiri eNi Cd mune mamwe maitiro (senge sintering) ndeye "memory effect", iyo inorambidza zvakanyanya kushandiswa kwemabhatiri. Zvisinei, Li-ion haina dambudziko iri zvachose.

(5) Kudzikira wega: Iyo yekuzviburitsa yega mwero weLi ion, iyo yakachajiswa zvizere pakamuri tembiricha uye inochengetwa kwemwedzi mumwe, ingangoita 2%, yakaderera zvakanyanya kupfuura 25-30% yeNi Cd uye 30-35% yeNi. uye mh.

(6) Kuchaja nekukurumidza uye kuburitsa: Hurukuro hunogona kusvika pamusoro pe80% yesimba rezita mushure memaminitsi makumi matatu ekuchaja, uye ikozvino phosphate iron mabhatiri anogona kusvika 90% yezvimiro zvezita mushure memaminitsi gumi ekuchaja.

(7) Kupisa kwekushanda kwepamusoro: Kupisa kwekushanda ndiko -25 ~ 55 ° C. Nekuvandudzwa kwe electrolyte uye electrode yakanaka, inotarisirwa kuwedzera kusvika -40 ~ 70 ° C.

2. Kuipa kwe lithium-ion mabhatiri

(1) Kuchembera: Kusiyana nemamwe mabhatiri anochajiswa, huwandu hwemabhatiri e-lithium-ion huchadzikira zvishoma nezvishoma, pasina huwandu hwekushandisa, asi hune chekuita nekupisa. Iyo inogoneka nzira ndeyokuti kupikisa kwemukati kunowedzera zvishoma nezvishoma, saka zvinowanzove zvichiratidzwa muzvigadzirwa zvemagetsi zvine maitiro akakwirira ekushanda. Kutsiva graphite ne lithium titanate kunoratidzika kuwedzera hupenyu.

(2) Kusakwanisa kutakura overcharging: Panguva yekuchajisa, yakawandisa yakamisikidzwa lithium ions ichagadzirisa zvachose mulatisi uye haigone kuburitswa, izvo zvinogona kutungamirira kuhupenyu hupfupi hwebhatiri uye kugadzirwa kwegasi kunokonzera gasi mabhubhu.

(3) Kusakwanisa kumira pamusoro pekubuda: Munguva yekubuda kwepamusoro, yakawandisa lithium ion inobviswa kubva kune electrode, iyo inogona kukonzera kuparara kwelattice, kupfupisa hupenyu, uye kukonzera kugadzirwa kwegasi, zvichiita kuti gasi mabhubhu.

(4) Nzira dzakawanda dzekudzivirira dzinodiwa: Nekuda kwekuti kushandiswa kusina kunaka kunogona kuderedza hupenyu uye kunyange kutungamirira kuputika, nzira dzakawanda dzekudzivirira dzakawedzerwa pakugadzirwa kwemabhatiri e-lithium-ion.

Dziviriro yedunhu: kudzivirira kuwandisa, kuburitsa zvakanyanya, kuwandisa, uye kupisa.

Exhaust port: kudzivirira kudzvinyirira kwakanyanya mukati mebhatiri.

Diaphragm maitiro: Iyo ine yakakwirira puncture kuramba kudzivirira mukati mapfupi maseketi; Kana kupisa kwemukati kwebhatiri kwakanyanyisa, inogona kuramba ichinyunguduka, kudzivirira lithium ions kubva pakupfuura, kuvhara maitiro ebheteri, uye kuwedzera kupikisa kwemukati (kusvika ku2kQ).

Muchidimbu, kusimudzira kweiyo lithium-ion bhatiri indasitiri iindasitiri ine simba inosimudzira nyika dzichiri kusimukira kunyika dzakasimukira.
