ʻO kahi hōʻuluʻulu piha o nā kikoʻī ʻike o ka hoʻokuʻu ponoʻī ʻana i ka pākaukau Lithium Ion

I kēia manawa,nā pākahi lithiumhoʻohana nui ʻia i nā ʻano mea kikohoʻe like ʻole e like me nā puke puke, nā pahu kiʻi kiʻi, a me nā pahupaʻiwikiō.Eia kekahi, loaʻa iā lākou nā manaʻo ākea i nā kaʻa, nā kahua kahua paʻa kelepona, anā kahua mana mālama ikehu.I kēia hihia, ʻaʻole ʻike wale ʻia ka hoʻohana ʻana i nā pākaukau e like me nā kelepona paʻalima, akā ʻoi aku ka nui ma ke ʻano o ka series a i ʻole ka like.pūʻolo pila.

ʻAʻole pili wale ka mana a me ke ola o ka puʻupuʻu pākahi i kēlā me kēia pākahi, akā pili pū kekahi i ke kūlike ma waena o kēlā me kēia pā.E hoʻopilikia nui ʻia ka hana ʻana o ka pūʻolo pākahi maikaʻi ʻole.

ʻO ke kūpaʻa o ka hoʻokuʻu ʻana iā ia iho he ʻāpana koʻikoʻi o nā mea hoʻoikaika.He ʻokoʻa nui ka pākaukau me ka hoʻokuʻu ʻana iā ia iho i ka SOC ma hope o kahi manawa o ka mālama ʻana, e hoʻopilikia nui i kona hiki a me ka palekana.

ʻO nā kumu nui o ka hoʻokuʻu ʻana iā ia iho: ʻo ka leaka uila kūloko i hana ʻia e ka hoʻokele uila ʻāpana o ka electrolyte a i ʻole nā ​​​​kaapuni pōkole kūloko;ma muli o ka insulation maikaʻi ʻole o ke apo sealing pākahiko a i ʻole ka lawa ʻole o ke kūpaʻa ʻana ma waena o ka pūpū alakaʻi waho (ke alakaʻi o waho, humidity) ʻO ka leaka electron waho ma muli o ka hopena electrode/electrolyte, e like me ka corrosion o ka anode a i ʻole ka hōʻemi ʻana o ka cathode. ma muli o ka electrolyte a me nā haumia;ka decomposition hapa o ka mea hana electrode;ka electrode i hana ʻia e nā huahana decomposition (mea hiki ʻole ke hoʻololi a me ke kinoea adsorbed) Passivation;ʻaʻahu mechanical o ka electrode a i ʻole ka piʻi ʻana o ke kūpaʻa ma waena o ka electrode a me ka ʻohi o kēia manawa.

ʻO ka hoʻokuʻu ʻana iā ia iho e hoʻemi i ka hiki i ka wā o ka mālama ʻana: ʻaʻole hiki ke hoʻomaka ke kaʻa ma hope o ke kaʻa ʻana no ka lōʻihi loa;He mea maʻamau nā mea a pau ma mua o ka waiho ʻana i ka pākaukau i loko o kahi waihona, a ʻike ʻia ka volta haʻahaʻa a i ʻole ka uila ʻole i ka wā i hoʻouna ʻia ai ka pila;kau ʻia ka GPS kaʻa ma ke kaʻa i ke kauwela a hoʻohana ʻia no kekahi manawa Manaʻo wau ʻaʻole lawa ka mana a i ʻole ka manawa hoʻohana, a ʻo ka pehu ʻana o ka pākaukau.

ʻO ka hoʻokuʻu ʻia ʻana o nā mea ʻino metala ke hoʻopaʻa ʻia ka nui o ka diaphragm pore, a hou aku i ka diaphragm e hana i kahi kaapuni pōkole kūloko, kahi e pōʻino ai ka palekana o ka pā.ʻO ka ʻokoʻa nui ma SOC hiki ke alakaʻi maʻalahi i ka overcharge a overdischarge o ka pākaukau.

Ma muli o ka hoʻokuʻu ʻole ʻana iā ia iho o nā pila, ʻokoʻa ka SOC o nā pā i loko o ka pā pākaukau ma hope o ka waiho ʻana, a ua hoʻemi ʻia ka hana pākaukau.Hiki i nā mea kūʻai ke ʻike pinepine i nā pilikia hoʻohaʻahaʻa i ka hana ma hope o ka loaʻa ʻana o kahi pahu pākaukau i mālama ʻia no kekahi manawa.I ka hiki ʻana o ka ʻokoʻa SOC ma kahi o 20%, ʻo 60% a i 70% wale nō ke koena o ka pākaukau hui.
