Pākuhi Lithium Polymer

pākahi lithium polymer

Lithium-ion a me ka lithium polymer mau ʻano pākaukau rechargeable i loaʻa ka lithium ma ke ʻano he mea hana electrochemical. ʻO nā pākahi Li-ion kekahi o nā ʻano kelepona kaulana loa o ka honua no ka uila uila. I kēia mau makahiki i hala iho nei, ua hoʻoulu ʻia ka hana nui o kēia mau cell e ka noi no nā kaʻa uila plug-in a me nā noi mālama ʻana.

ʻO nā pākahi Lithium-ion ka mua o ka pāʻoihana kūleʻa hoʻihoʻi hou ʻana o nā ʻano āpau, e ʻike nui ʻia ai lākou. Ua lanakila lākou i ka mākeke uila uila ma muli o ko lākou kiʻekiʻe kiʻekiʻe o ka ikehu, ka hoʻouka wikiwiki a me ka nele o ka hopena hoʻomanaʻo. ʻO ka puka kiʻekiʻe o kēia manawa o nā mea hana mana lithium-ion e kūpono iā lākou no nā noi e like me ka hana lāʻau, wili a me ka wili.

ʻO nā ʻōlima polimer lithium he ʻuʻuku, pā pālahalaha i loaʻa i nā mea anode interleaved a me nā mea cathode i hoʻokaʻawale ʻia e kahi polymer electrolyte. Hiki i ka polymer electrolyte ke hoʻohui i ka maʻalahi i ka pākaukau, e maʻalahi i ka hoʻopili ʻana i nā wahi liʻiliʻi ma mua o nā pā lithium-ion.

ʻO ke ʻano maʻamau o ka pākaukau lithium polymer e hoʻohana ana i kahi anode lithium ion a me kahi electrolyte organik, me kahi electrode maikaʻi ʻole i hana ʻia me ke kalapona a me ka anode composite cathode material. ʻIke ʻia kēia ma ke ʻano he lithium polymer primary cell.

ʻO ke ʻano maʻamau o ka pākaukau lithium-ion e hoʻohana ana i kahi anode metala lithium, kahi cathode ʻeleʻele kalapona a me kahi electrolyte organik. ʻO ka electrolyte kahi hopena o kahi mea hoʻoheheʻe organik, ka paʻakai lithium a me ka polyvinylidene fluoride. Hiki ke kūkulu ʻia ka anode mai ke kalapona a i ʻole graphite, hana maʻamau ka cathode mai ka manganese dioxide.

Hana maikaʻi nā ʻano ʻokoʻa ʻelua i nā haʻahaʻa haʻahaʻa akā ʻoi aku ka kiʻekiʻe o nā pākahi lithium polymer ma mua o ka nui like o ke kelepona lithium-ion. Hāʻawi kēia i nā pahu liʻiliʻi liʻiliʻi a me nā ʻeke kaumaha māmā no nā polokalamu uila uila e hoʻohana ana i ka 3.3 volts a i ʻole ka liʻiliʻi, e like me nā eReaders a me nā kelepona.

ʻO ka volts nominal no nā pūnaewele lithium-ion he 3.6 volts, aʻo nā pā lithium polymer e loaʻa ana mai ka 1.5 V a hiki i ka 20 V. He ʻoi aku ka nui o ka ikehu o ka lithium-ion ma mua o ka nui like lithium polymer pākahiko no ko lākou anode liʻiliʻi. ʻoi aku ka pilina ma loko o ka anode.
