Hiki ke hoʻokaʻawale nui ʻia nā pila i ʻekolu mau māhele: nā pila kemika, nā pila kino a me nā pila olaola. ʻO nā pila kemika ka mea i hoʻohana nui ʻia i nā kaʻa uila.
Pākahiko kemika: ʻO ka pākahiko kemika kahi mea hana e hoʻololi i ka ikehu kemika i ikehu uila ma o nā hopena kemika. Loaʻa iā ia nā electrodes a me nā electrolytes maikaʻi a maikaʻi ʻole.
Pākahiko kino: Hoʻololi ka pākahiko kino i ka ikehu kino (e like me ka ikehu lā a me ka ikehu mechanical) i ikehu uila ma o nā loli kino.
Ka hoʻokaʻawale ʻana o nā pākahiko kemika: Mai kahi manaʻo kūkulu, hiki ke hoʻokaʻawale ʻia i ʻelua mau māhele: nā pākahi mālama (me nā pākahi mua a me nā pākahi lua) a me nā cell wahie. Nā pākahi mua: hiki ke hoʻohana ʻia hoʻokahi wale nō, ʻaʻole hiki ke hoʻihoʻi ʻia ka mea hana, liʻiliʻi ka hoʻokuʻu ponoʻī, nui ke kū'ē kūloko, a kiʻekiʻe ke ʻano o ka nuipa a me ka nuipa kikoʻī.
Nā pila lua: hiki ke hoʻouka a hoʻokuʻu pinepine ʻia, hiki ke hoʻohuli ʻia ka mea hana, a hoʻohana nui ʻia i nā mea hoʻouka like ʻole. ʻO ka hapa nui o nā hiʻohiʻona ma ka mākeke e hoʻohana nei i nā pila hoʻouka hou lua e hoʻokele i ke kaʻa. Ua māhele ʻia nā pila lua i nā pila lead-acid, nā pila nickel-cadmium, nā pila nickel-metal hydride a me nā pila lithium e like me nā mea electrode maikaʻi like ʻole. I kēia manawa, hoʻohana nui nā ʻoihana kaʻa ma ka mākeke i nā pila lithium, a hoʻohana kekahi i nā pila nickel-metal hydride.
Ka wehewehe ʻana o ka pākahiko lithium
ʻO ka pākahiko Lithium kahi pākahiko e hoʻohana ana i ka metala lithium a i ʻole ka lithium alloy ma ke ʻano he mea electrode maikaʻi a maikaʻi ʻole paha a me ka hopena electrolyte ʻaʻole wai.
ʻO ke kaʻina hana hoʻouka a hoʻokuʻu ʻana o ka pākahiko lithium e hilinaʻi nui ʻia i ka neʻe ʻana o nā ion lithium (Li+) ma waena o nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole. I ka wā e hoʻouka ai, 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 waiwai lithium; ʻo ka ʻaoʻao ʻē aʻe ka ʻoiaʻiʻo i ka wā e hoʻokuʻu ai.
ʻO ke kumumanaʻo electrochemical o ka pākahiko lithium-ion
ʻO ke ʻano hana electrode maikaʻi: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
ʻO ke ʻano hana electrode maikaʻi ʻole: C + xLi+ + xe- → CLix
He kiʻekiʻe ka nui o ka ikehu o nā pākahiko Lithium-ion, lōʻihi ke ola a haʻahaʻa ka hoʻokuʻu ponoʻī, a hoʻohana nui ʻia i nā kelepona paʻalima, nā kamepiula lawe lima a me nā kaʻa uila.
Ua māhele nui ʻia nā kahua noi o nā pila lithium-ion i ka mana a me ka mana ʻole. ʻO nā kahua mana o nā noi pila lithium-ion e komo pū ana me nā kaʻa uila, nā mea hana mana, a me nā mea ʻē aʻe; ʻo nā kahua mana ʻole e komo pū me nā mea uila mea kūʻai aku a me nā kahua mālama ikehu, a me nā mea ʻē aʻe.
ʻO ka haku mele ʻana a me ka hoʻokaʻawale ʻana o nā pila lithium
ʻO nā pila Lithium-ion ka mea nui i haku ʻia me ʻehā ʻāpana: nā mea electrode maikaʻi, nā mea electrode maikaʻi ʻole, nā electrolytes a me nā mea hoʻokaʻawale pila. Hoʻopilikia nui nā mea electrode maikaʻi ʻole i ka pono mua a me ka hana pōʻaiapuni o nā pila lithium-ion. Ua māhele nui ʻia nā electrodes maikaʻi ʻole o ka pila Lithium i ʻelua mau ʻāpana: nā mea kalapona a me nā mea ʻaʻole kalapona. ʻO ka noi i hoʻonohonoho nui ʻia i ka mākeke ʻo ia ka mea electrode graphite maikaʻi ʻole i waena o nā mea kalapona, kahi i loaʻa ai nā noi ʻoihana nui o ka graphite artificial a me ka graphite kūlohelohe. ʻO nā electrodes maikaʻi ʻole i hoʻokumu ʻia i ka Silicon ke kikowaena o ka noiʻi e nā mea hana electrode maikaʻi ʻole nui a ʻo ia kekahi o nā mea electrode maikaʻi ʻole hou e hoʻohana nui ʻia ma ka wā e hiki mai ana.
Ua hoʻokaʻawale ʻia nā pila Lithium-ion i nā pila lithium cobalt oxide, nā pila lithium hao phosphate, nā pila ternary, a pēlā aku e like me nā mea electrode maikaʻi;
Wahi a ke ʻano o ka huahana, ua māhele ʻia lākou i nā pila huinaha, nā pila cylindrical a me nā pila palupalu;
Wahi a nā hiʻohiʻona noi, hiki ke hoʻokaʻawale ʻia i nā mea uila mea kūʻai aku, ka mālama ikehu a me nā pila mana. I waena o lākou, hoʻohana nui ʻia nā pila lithium mea kūʻai aku i nā huahana 3C; hoʻohana nui ʻia nā pila mālama ikehu i ka mālama ikehu o ka home a me ka mālama ikehu ʻōnaehana mana kūʻokoʻa i hoʻokaʻawale ʻia e like me ka ikehu lā a me ka hana mana makani; hoʻohana nui ʻia nā pila mana i nā kaʻa uila like ʻole, nā mea hana uila a me nā kaʻa ikehu hou.

E hoʻomau ʻo Heltec i ka hoʻonui ʻana i ka ʻike ʻepekema kaulana e pili ana i nā pila lithium. Inā makemake ʻoe, hiki iā ʻoe ke hoʻolohe iā ia. I ka manawa like, hāʻawi mākou iā ʻoe i nā pā pila lithium kiʻekiʻe no ʻoe e kūʻai ai a hāʻawi i nā lawelawe i hana ʻia e hoʻokō i kāu mau pono.
ʻO Heltec Energy kāu hoa hilinaʻi i ka hana ʻana i nā pā pila. Me kā mākou nānā mau ʻana i ka noiʻi a me ka hoʻomohala ʻana, me kā mākou laulā piha o nā mea pono pā pila, hāʻawi mākou i nā hopena kū hoʻokahi e hoʻokō i nā pono e ulu nei o ka ʻoihana. ʻO kā mākou kūpaʻa i ka maikaʻi loa, nā hoʻonā i hana kūikawā ʻia, a me nā pilina ikaika o nā mea kūʻai aku e hoʻolilo iā mākou i koho koho no nā mea hana a me nā mea hoʻolako pā pila ma ka honua holoʻokoʻa.
Inā he mau nīnau kāu a makemake paha e ʻike hou aku, mai kānalua e leka uila mai iā mākoue hoʻokaʻaʻike mai iā mākou.
