ʻO ka pākaukau Lithium-ionnā kumu pahū:
1. Polarization kūloko nui;
2. Hoʻomoʻa ka ʻāpana pole i ka wai a hana me ka pahu kinoea electrolyte;
3. ʻO ka maikaʻi a me ka hana o ka electrolyte pono'ī;
4. ʻAʻole kūpono ka nui o ka wai i nā koi kaʻina hana;
5. Poor sealing hana o ka laser kuʻihao ma ka hui kaʻina hana a me ka ea leakage ke ana ea leakage;
6. He maʻalahi ka lepo, pole ʻāpana lepo e alakaʻi i ka micro-pōkole kaapuni ma kahi mua;
7. ʻOi aku ka mānoanoa o nā ʻāpana pole maikaʻi a maikaʻi ʻole ma mua o ke kaʻina hana, a paʻakikī ke komo ʻana i ka pūpū;
8. ʻAʻole maikaʻi ka hoʻokō ʻana i ka hoʻoheheʻe ʻana i ka wai, ʻaʻole maikaʻi ka hoʻokō ʻana i ka pahu kila;
9. ʻO ka mānoanoa o ka paia o ka pūpū e komo mai ana, pili ka hoʻololi ʻana o ka pūpū i ka mānoanoa;
10. Ma waho o ka wela ambient kiʻekiʻe kekahi kumu nui o ka pahū.
Nā hana palekana i lawe ʻia e ka pākaukau:
ʻO ka pākaukau Lithium-ionua hoʻonui ʻia nā kelepona i kahi volta kiʻekiʻe ma mua o 4.2V a e hoʻomaka ana e hōʻike i nā hopena ʻaoʻao.ʻO ke kiʻekiʻe o ka volta overcharge, ʻoi aku ka kiʻekiʻe o ka pōʻino.Ke ʻoi aku ka nui o ka volta o kahi cell lithium ma mua o 4.2V, ʻoi aku ka liʻiliʻi o ka hapalua o nā mana lithium i loko o ka mea electrode maikaʻi, a hāʻule pinepine ka waihona waihona, e hāʻule mau ana i ka mana pākaukau.Inā hoʻomau ka hoʻopaʻa ʻana, ʻoiai ua piha ka waihona o ka electrode maikaʻi ʻole i nā atom lithium, e hōʻiliʻili ka metala lithium ma hope o ka ʻili o ka mea electrode maikaʻi ʻole.E ulu ana kēia mau mea lithium i nā kristal dendritic mai ka ʻili anode i ke kuhikuhi o nā ion lithium.E hele kēia mau kristal metala lithium i ka pepa diaphragm a hoʻopili pōkole i nā electrodes maikaʻi a maikaʻi ʻole.I kekahi manawa, pahū ka pākaukau ma mua o ke kaapuni pōkole, ʻo ia ke kumu o ka overcharging kaʻina, e haki ka electrolyte a me nā mea ʻē aʻe e ʻike i ke kinoea, e hoʻoheheʻe ʻia ka pūpū pākaukau a i ʻole ka puʻupuʻu puʻupuʻu puʻupuʻu, no laila ka oxygen i loko o ka hopena me ka hōʻiliʻili. o nā ʻātoma lithium ma ka ʻili o ka electrode maikaʻi ʻole, a laila pahū.
No laila, i ka wā e hoʻouka ainā pākahi lithium-ion, pono e hoʻonoho i ka palena o ka volta kiʻekiʻe i mea e noʻonoʻo ai i ke ola, ka hiki, a me ka palekana o ka pākaukau i ka manawa like.ʻO ka palena kiʻekiʻe maikaʻi loa o ka hoʻouka uila he 4.2 V. Pono e loaʻa kahi palena haʻahaʻa haʻahaʻa i ka wā e hoʻokuʻu ai i nā cell lithium.Ke hāʻule ka uila uila ma lalo o 2.4V, e hoʻomaka ana kekahi o nā mea hana e luku ʻia.A no ka hoʻokuʻu ʻana o ka pākaukau, ʻoi aku ka lōʻihi o kou kau ʻana i ka haʻahaʻa haʻahaʻa, no laila, ʻoi aku ka maikaʻi o ka hoʻokuʻu ʻana i ka 2.4V ma mua o ka hoʻomaha.ʻO ka ikehu i hoʻokuʻu ʻia i loko o ka manawa mai 3.0V a i 2.4V wale nō ka helu ma kahi o 3% o ka mana o kahi pākahi lithium-ion.No laila, ʻo 3.0V kahi ʻokiʻoki maikaʻi loa no ka hoʻokuʻu ʻana.I ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, ma waho aʻe o ka palena o ka voltage, pono pū ka palena o kēia manawa.Ke kiʻekiʻe loa ke ʻano o kēia manawa, ʻaʻohe manawa o nā lithium ion e komo i loko o ke keʻena mālama a e hōʻiliʻili ma ka ʻili o ka mea.
ʻO kēia mau meanā iona lithiumloaʻa nā electrons a crystallize lithium atoms ma ka ʻili o ka mea, ʻo ia ka mea like me ka overcharging a hiki ke pilikia.Ina nahaha ka pahu pahu, e pahū.No laila, ʻo ka pale ʻana o nā pā lithium-ion pono e hoʻokomo i ʻekolu mau mea: ka palena kiʻekiʻe o ka hoʻouka uila, ka palena haʻahaʻa o ka hoʻokuʻu ʻana, a me ka palena kiʻekiʻe o kēia manawa.ʻO nā pahu pahu pahu lithium-ion maʻamau, ma waho aʻe o nā pūnaewele pūnaewele lithium-ion, e loaʻa kahi pale pale, he mea nui kēia pale pale e hoʻolako i kēia mau paleʻekolu.
