Ua lilo nā kukui alanui o ka lā i mea koʻikoʻi o nā ʻōnaehana kūlanakauhale o kēia wā, e hāʻawi ana i kahi hoʻonā kukui ʻoluʻolu a me ke kumu kūʻai.Ke hilinaʻi nei kēia mau kukui i nā ʻano pākahi like ʻole e mālama i ka ikehu i hopu ʻia e nā panela lā i ka lā.
1. Hoʻohana mau nā kukui alanui o ka lā i nā ʻaʻa lithium hao phosphate:
He aha ke ʻano o ka pā lithium iron phosphate?
ʻO ka pākaukau lithium iron phosphate he ʻano pākaukau lithium-ion e hoʻohana ana i ka lithium iron phosphate (LiFePO4) ma ke ʻano he cathode a me ke kalapona e like me ka mea anode.ʻO 3.2V ka volt nominal o ke kelepona hoʻokahi, a ʻo ka volta ʻoki ʻoki i ka hoʻouka ʻana ma waena o 3.6V a me 3.65V.I ka wā e hoʻouka ai, wehe ʻia nā ion lithium mai ka lithium iron phosphate a hele i ka electrolyte i ka anode, e hoʻokomo iā lākou iho i loko o ka mea kalapona.I ka manawa like, ua hoʻokuʻu ʻia nā electrons mai ka cathode a hele i ke kaapuni waho i ka anode e mālama i ke koena o ka hopena kemika.I ka wā o ka hoʻokuʻu ʻana, neʻe nā ion lithium mai ka anode a i ka cathode ma o ka electrolyte, aʻo nā electrons e neʻe mai ka anode a i ka cathode ma o ke kaapuni o waho, e hāʻawi ana i ka ikehu i ka honua o waho.
Hoʻohui ka pākaukau lithium iron phosphate i nā pono he nui: kiʻekiʻe ka ikehu kiʻekiʻe, ka nui paʻa, ka hoʻopiʻi wikiwiki, ka lōʻihi, a me ke kūpaʻa maikaʻi.Eia nō naʻe, ʻo ia ka mea ʻoi aku ka pipiʻi ma waena o nā pila a pau.Kākoʻo maʻamau ia i ka 1500-2000 mau koina pōʻai hohonu a hiki ke hoʻomau i 8-10 mau makahiki ma lalo o ka hoʻohana maʻamau.Hana ia i loko o kahi ākea ākea o -40 ° C a i 70 ° C.
2. Hoʻohana mau ʻia nā ʻeke colloidal i nā kukui alanui o ka lā.
He aha ka pila colloidal?
ʻO ka pākaukau colloidal kahi ʻano o ka pākī-ʻakika i hoʻohui ʻia kahi mea gelling i ka ʻakika sulfuric, e hoʻohuli ana i ka electrolyte i kahi kūlana gel-like.Ua kapa ʻia kēia mau pākahi, me kā lākou gelled electrolyte, ʻo nā ʻeke colloidal.ʻAʻole e like me nā pākaʻi lead-acid maʻamau, ʻoi aku ka maikaʻi o nā pā colloidal ma luna o nā waiwai electrochemical o ke kahua kumu electrolyte.
ʻAʻole mālama ʻia nā ʻeke Colloidal, e lanakila ana i nā pilikia mālama pinepine e pili ana i nā pākī lead-acid.Hoʻololi ko lākou ʻano kūloko i ka wai sulfuric acid electrolyte me kahi ʻano gelled, hoʻonui nui i ka mālama ʻana i ka mana, ka hiki ke hoʻokuʻu, ka hana palekana, a me ke ola, i kekahi manawa ʻoi aku ka maikaʻi o nā pākahi lithium-ion ternary ma ke ʻano o ke kumukūʻai.Hiki ke hana i nā pila Colloidal i loko o kahi mahana wela o -40°C a i 65°C, i mea kūpono ia no ka hoʻohana ʻana i nā wahi anu.Hiki ke hoʻohana pono ʻia ma lalo o nā kūlana koʻikoʻi like ʻole.ʻO kā lākou ola lawelawe he pālua a ʻoi aku paha ke hoʻohālikelike ʻia me nā pākaukau lead-acid maʻamau.
3. NMC Lithium-Ion batteries i hoʻohana mau ʻia i nā kukui alanui o ka lā.
Hāʻawi nā pākahi lithium-ion NMC i nā pono he nui: ka ikehu kikoʻī kiʻekiʻe, ka nui compact, a me ka hoʻouka wikiwiki.Kākoʻo maʻamau lākou i ka 500-800 mau koina pōʻaiapuni hohonu, me ke ola e like me nā pihi colloidal.ʻO kā lākou pae wela hana mai -15°C a 45°C.Eia nō naʻe, loaʻa i nā pākahi lithium-ion NMC nā drawbacks, me ka liʻiliʻi o ka paʻa o loko.Inā hana ʻia e nā mea hana ʻike ʻole, aia ka pilikia o ka pahū ʻana i ka wā o ka overcharging a i ʻole ma nā wahi wela kiʻekiʻe.
4. ʻO nā ʻokoʻa kepau-acid i hoʻohana mau ʻia i nā kukui alanui o ka lā.
Loaʻa i nā pākaʻi ʻakika keʻokeʻo nā electrodes i haku ʻia me ke kēpau a me ke kēpau oxide, me kahi electrolyte i hana ʻia me ka solution sulfuric acid.ʻO nā pōmaikaʻi koʻikoʻi o nā pākī lead-acid, ʻo ia ka volta paʻa a me ke kumu kūʻai haʻahaʻa.Eia nō naʻe, loaʻa iā lākou ka ikehu kikoʻī haʻahaʻa, ka hopena i ka nui o ka leo i hoʻohālikelike ʻia me nā pākaukau ʻē aʻe.He pōkole ko lākou ola ʻana, kākoʻo maʻamau i ka 300-500 mau kumukūʻai hohonu, a pono lākou e mālama pinepine.ʻOiai ʻo kēia mau hemahema, hoʻohana nui ʻia nā pākaʻi lead-acid i ka ʻoihana kukui alanui solar ma muli o kā lākou uku kumukūʻai.
ʻO ke koho ʻana o ka pākaukau no nā kukui alanui o ka lā e pili ana i nā mea e like me ka pono o ka ikehu, ke ola, nā pono mālama, a me ke kumukūʻai.Loaʻa i kēlā me kēia ʻano pākaukau kona mau pono kūʻokoʻa, e mālama ana i nā koi a me nā kūlana like ʻole, e hōʻoiaʻiʻo ana e noho mau nā kukui alanui o ka lā i mea hoʻonā kukui paʻa.
