Hoʻolauna:
Hiki ke hoʻokaʻawale nui ʻia nā ʻokoʻa i ʻekolu mau ʻāpana: ʻo nā pākahi kemika, nā ʻeke kino, a me nā pā ola. ʻO nā pākiki kemika ka mea i hoʻohana nui ʻia i nā kaʻa uila.
ʻO ke kinikini kemika: ʻO ke kinikini kekahi mea e hoʻololi ai i ka ikehu kemika i ikehu uila ma o nā hopena kemika. Loaʻa iā ia nā electrodes maikaʻi a maikaʻi ʻole a me nā electrolytes.
Ka pila kino: Hoʻololi ka pila kino i ka ikehu kino (e like me ka ikehu lā a me ka ikehu mechanical) i ikehu uila ma o nā hoʻololi kino.
Ka hoʻokaʻawale ʻana i nā pākaukau kemika: Mai kahi hiʻohiʻona o ka nānā ʻana, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana: ʻo nā ʻeke hoʻopaʻa (me nā ʻeke kumu mua a me nā ʻeke lua) a me nā ʻāpana wahie. ʻO nā ʻanuʻu kumu: hiki ke hoʻohana hoʻokahi wale nō, ʻaʻole hiki ke hoʻihoʻi ʻia ka mea hana, liʻiliʻi ka hoʻokuʻu ʻana iā ia iho, nui ke kūpaʻa kūloko, a kiʻekiʻe ka mana kikoʻī a me ka nui kikoʻī.
ʻO nā pihi lua: hiki ke hoʻopiʻi ʻia a hoʻokuʻu pinepine ʻia, hiki ke hoʻohuli ʻia ka mea hana, a hoʻohana nui ʻia i nā mea hoʻoili like ʻole. ʻO ka hapa nui o nā hiʻohiʻona ma ka mākeke i kēia manawa e hoʻohana nei i nā ʻokoʻa lua e hoʻihoʻi hou i ke kaʻa. Hoʻokaʻawale ʻia nā ʻāpana lua i nā ʻāpana lead-acid, nickel-cadmium batteries, nickel-metal hydride batteries a me lithium batteries e like me nā mea electrode maikaʻi like ʻole. I kēia manawa, hoʻohana nui nā hui kaʻa i ka mākekenā pākahi lithium, a ke hoʻohana nei kekahi i nā ʻakika nickel-metal hydride.
ʻO ka wehewehe ʻana o ka pā lithium
Pākuʻi lithiumʻO ia ka pākaukau e hoʻohana ana i ka metala lithium a i ʻole lithium alloy ma ke ʻano he mea electrode maikaʻi a maikaʻi ʻole paha a me ka hopena electrolyte wai ʻole.
ʻO ke kaʻina hana a me ka hoʻokuʻu ʻana o ka pā lithium e hilinaʻi nui i ka neʻe ʻana o nā ion lithium (Li +) ma waena o nā electrodes maikaʻi a maikaʻi ʻole. I ka wā e hoʻouka ai, ua hoʻokaʻawale ʻia nā ion lithium mai ka electrode maikaʻi a hoʻokomo ʻia i loko o ka electrode maikaʻi ʻole ma o ka electrolyte, a aia ka electrode maikaʻi ʻole i kahi kūlana lithium-rich; ʻo ka ʻaoʻao ʻē aʻe ke hoʻokuʻu.
ʻO ka loina electrochemical o ka pā lithium-ion
ʻO ke kumu hoʻohālikelike electrode maikaʻi: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
ʻO ke kumu hoʻohālikelike electrode ʻino: C + xLi+ + xe- → CLix
He kiʻekiʻe ka ikehu kiʻekiʻe o nā pākahi Lithium-ion, lōʻihi ke ola a me ka haʻahaʻa haʻahaʻa haʻahaʻa, a hoʻohana nui ʻia i nā kelepona paʻalima, nā kamepiula a me nā kaʻa uila.
Nā kahua noi onā pākahi lithiumua mahele nui ia i ka mana a me ka mana ole. ʻO nā kahua mana o nā noi pākaukau lithium-ion e pili ana i nā kaʻa uila, nā mea hana mana, etc.; ʻO nā kahua mana ʻole e pili ana i nā mea uila uila a me nā māla mālama ikehu, etc.
Ka hoʻohui a me ka hoʻokaʻawale ʻana o nā pā lithium
ʻO ka nui o nā ʻāpana lithium he ʻehā mau ʻāpana: nā mea electrode maikaʻi, nā mea electrode maikaʻi ʻole, nā electrolytes a me nā mea hoʻokaʻawale pākaukau. Hoʻopili nui nā mea electrode maikaʻi ʻole i ka hana mua a me ka hana pōʻai o nā pā lithium-ion. Hoʻokaʻawale ʻia nā electrodes maikaʻi ʻole Lithium i ʻelua mau ʻāpana: nā mea kalapona a me nā mea non-carbon. ʻO ka noi ʻoi loa ma ka mākeke ʻo ka graphite negative electrode material ma waena o nā mea kalapona, ma waena o nā graphite artificial a me nā graphite kūlohelohe i loaʻa nā noi ʻoihana nui. ʻO nā electrodes maikaʻi ʻole e pili ana i ka silikon ke kumu o ka noiʻi ʻana e nā mea hana electrode maikaʻi ʻole nui a ʻo ia kekahi o nā mea electrode maikaʻi ʻole hou e hoʻohana nui ʻia i ka nui i ka wā e hiki mai ana.
ʻO nā pākahi liʻiliʻiua hoʻokaʻawale ʻia i loko o nā pākahi lithium cobalt oxide, lithium iron phosphate batteries, ternary batteries, etc. e like me nā mea electrode maikaʻi;
E like me ke ʻano o ka huahana, ua māhele ʻia lākou i nā pākahi square, nā ʻāpana cylindrical a me nā ʻāpana palupalu;
Wahi a nā hiʻohiʻona noi, hiki ke hoʻokaʻawale ʻia lākou i nā mea uila uila, mālama ʻana i ka ikehu a me nā pihi mana. Ma waena o lākou, ua hoʻohana nui ʻia nā pā lithium consumer i nā huahana 3C; hoʻohana nui ʻia nā pākaukau mālama ikehu i ka mālama ʻana i ka ikehu hale a puʻunaue ʻia ka ʻōnaehana mana kūʻokoʻa e mālama i ka ikehu e like me ka ikehu lā a me ka hana makani; Hoʻohana nui ʻia nā pihi mana i nā kaʻa uila like ʻole, nā mea uila a me nā kaʻa ikehu hou.
Ka hopena
E hoʻomau ʻo Heltec i ka ʻike ʻepekema kaulana e pili ananā pākahi lithium. Inā hoihoi ʻoe, hiki iā ʻoe ke hoʻolohe iā ia. Ma ka manawa like, hāʻawi mākou iā ʻoe i nā pā uila lithium kiʻekiʻe no ʻoe e kūʻai a hāʻawi i nā lawelawe maʻamau e hoʻokō i kāu mau pono.
ʻO Heltec Energy kāu hoa hilinaʻi ma ka hana ʻana i ka pākaukau. Me ko mākou manaʻo hoʻomau i ka noiʻi a me ka hoʻomohala ʻana, i hui pū ʻia me kā mākou ʻāpana piha o nā lako pākaukau, hāʻawi mākou i nā ʻoluʻolu hoʻokahi e hoʻokō i nā pono e ulu nei o ka ʻoihana. ʻO kā mākou kūpaʻa i ka maikaʻi, nā hoʻonā i hoʻohālikelike ʻia, a me nā hui kūʻai ikaika e hoʻolilo iā mākou i ke koho koho no nā mea hana pākaukau a me nā mea hoʻolako ma ka honua holoʻokoʻa.
Inā he mau nīnau kāu a makemake paha e aʻo hou aku, e ʻoluʻolu e ʻoluʻolue launa mai ia makou.
