Tulee supercapacitors na batrị, dị ka egosiri na elu-mgbasa ozi batrị nwere electrode ọkpụrụkpụ atọ dị iche iche, ma nnukwu ike njupụta, na elu ike njupụta. Isi Iyi: Ebee ka American Chemistry Society dị, ọ dị ka ọganiihu na teknụzụ batrị, mana ọ bụghị batrị. Ụgwọ nke ụlọ ọrụ Nanotekinstruments, Inc.

na ndị enyemaka ya, Angstronmaterials, Inc. nke Ohton, mepụtara nkọwapụta ọhụrụ, nke a na-eji emepụta akụrụngwa nchekwa ike, dabere na ngwa ngwa ngwa ngwa nke ọnụ ọgụgụ dị ukwuu nke ion lithium na electrode, electrode a nwere nnukwu graphene. Ngwaọrụ nchekwa ike a nwere ike ịba uru nke ukwuu maka ụgbọ ala eletrik, nke nwere ike ibelata oge nchaji, belata site na ihe na-erughị otu nkeji site na awa.

Ngwa ndị ọzọ nwere ike ịgụnye nchekwa ike mmeghari ohuru (dịka ọmụmaatụ, nchekwa anyanwụ na ike ikuku) yana grid smart. Ndị nchọpụta ahụ kwuru na ngwaọrụ ọhụrụ a bụ batrị mgbanwe lithium ion maka ọrụ graphene n&39;elu, ma ọ bụ karịa, batrị mgbasa ozi elu (SMCS: Surface-Mediatedcells). Ọ bụ ezie na akụrụngwa dị ugbu a na-eji ihe na akụrụngwa emepeghị emepe, ha nwere ike karịa batrị lithium-ion na nnukwu ike.

Ngwaọrụ ọhụrụ a nwere ike ịnye 100 kilowatts kwa kilowatt nke batrị, 100 ugboro dị elu karịa batrị lithium-ion azụmahịa, 10 ugboro dị elu karịa supercapacitor. N&39;ịdị elu ike njupụta, ngwa ngwa nnyefe ike na-agba ọsọ (nwere ike ịkpata ọsọ ọsọ ọsọ). Na mgbakwunye, batrị ọhụrụ a nwere ike ịchekwa njupụta ike nke 160 watts kwa kilogram nke batrị, nke yiri batrị lithium-ion nke a na-ere ahịa, ugboro 30 dị elu karịa nnukwu ike omenala.

Ka ike njupụta dị ukwuu, ka enwere ike ịchekwa ike karị, ka a na-echekwa ike karịa (na ogologo oge ịnya ụgbọ ala eletrik). Ọ bụrụ na e nwere otu ngwá arọ, na nke ugbu a elu-mediated batrị na lithium-ion batrị nwere ike ji mee ihe maka electric ụgbọ ala, na nchoputa nke Nano Instrument na Angerstron Materials Company Joint nchoputa Jiang Bauz (Borz.jang) Ọ na-kwuru na anyị elu-mediated batrị yiri nke ugbu a lithium-ion batrị, nwere ike n&39;ihu na-amụba ya ike density.

Otú ọ dị, n&39;ụkpụrụ, enwere ike ịcha batrị na-agbanye n&39;elu n&39;ime nkeji ole na ole (nwere ike ọ gaghị erughị otu nkeji), karịa awa, dịka batrị lithium-ion nke eji na ụgbọ ala eletrik. Jiang Bauldz na onye otu ya na Nanotechnology Instrument Co., Ltd.

na Angersmia Material Company ebipụtala ọmụmụ ihe a, nke bụ ọmụmụ ihe nchekwa nchekwa ike nke ọgbọ ọzọ, nke e bipụtara na "Nano Express" (Nanoletters) kachasị ọhụrụ. Ụlọ ọrụ abụọ a bụ ọkachamara na ịzụ ahịa nke nanomaterials, Angerstrong bụ nnukwu nano-granite (NGPS: Nanographeneplatelets) na-emepụta. Dịka ndị nyocha na-akọwa na nyocha ha, enwere ike na adịghị ike nke ha na nchekwa ike, batrị na ndị nwere ike.

Ọ bụ ezie na ike njupụta nke lithium ion batrị (120-150 watt / kg) dị nnọọ elu karịa supercapacitor (5 watt / kg), batrị a nwere obere ike njupụta (1 kW / kg batrị) , Tụlee 10 kW / kg batrị). Ọtụtụ ndị otu nyocha agbaala mbọ iji gbakwunye njupụta ike nke batrị lithium-ion, meziwanye njupụta ike nke supercapacitor, mana mpaghara abụọ a ka nwere nnukwu nsogbu. N&39;ihi na a na-enye usoro ọhụrụ, enwere ike iji ya maka ngwaọrụ nchekwa ike, ya mere batrị a na-agbanye n&39;elu na-enye ndị nchọpụta ohere ịgafe ihe ịma aka ndị a.

Zụlite ngwaọrụ nchekwa ike ọhụrụ a, na-ebelata ohere dị n&39;etiti arụmọrụ nke batrị lithium ion na supercapacitor, Jiang Bauz kwuru. Ihe ka mkpa, nke a fundamentally ọhụrụ kpuchie maka n&39;ichepụta ike nchekwa ngwaọrụ, na-enyere ndị na-eme nnyocha nweta elu ike njupụta, ma elu ike njupụta, na-enweghị na-achụ otu n&39;ihi na ọzọ. Igwe ọkụ batrị na-agbanye n&39;elu nwere nnukwu ebe dị elu, nke mere na ọnụ ọgụgụ buru ibu nke ions na-ebugharị ngwa ngwa, na-eweta oge nchaji ngwa ngwa.

Isi mmalite: Isi ihe na-arụ ọrụ batrị na-arụ ọrụ n&39;elu nke American Chemistry, bụ cathode na anode nwere nnukwu elu graphene. Mgbe ị na-emepụta batrị, ndị na-eme nchọpụta na-etinye lithium metal (n&39;ụdị nke irighiri ma ọ bụ ígwè foil) na anode. Na okirikiri mbupu nke mbụ, lithium bụ ionized, ọnụọgụ ion lithium wetara karịa na batrị lithium ion.

Mgbe a na-eji batrị eme ihe, ion ndị a na-akwaga na cathode site na mmiri mmiri electrolyte, n&39;ime oghere nke cathode iji ruo nnukwu graphene dị na cathode. N&39;oge usoro ịchaji, nnukwu ọnụọgụ lithium ion na-agba ọsọ ngwa ngwa site na cathode gaa na anode. Ebe dị elu nke electrode dị ukwuu, nke mere na nnukwu ion ion na-ebugharị ngwa ngwa, ike dị elu na ike ike.

Ndị nchọpụta ahụ kọwara na elu nke electrode porous (kama na ngọngọ electrode, dị ka batrị dị na batrị), anaghị eri oge na-ewe usoro ntinye. N&39;oge usoro a, a ghaghị itinye ion lithium n&39;etiti electrodes, nke mejupụtara oge batrị dị mkpa. N&39;ime ọmụmụ ihe a, ọ bụ ezie na ndị na-eme nchọpụta na-eji ọnụ ọgụgụ dị ukwuu nke ụdị graphite dị iche iche, a kwadebere ụdị graphene dị iche iche (oxidized, less single-layer and multi-layer graphene), ma a na-enyocha ihe ndị a na nhazi ndị a ọzọ iji kwalite ngwaọrụ a.

N&39;otu aka ahụ, ndị nchọpụta ahụ na-eme atụmatụ ịmụba ndụ okirikiri nke batrị a. Ka ọ dị ugbu a, ha na-achọpụta na ngwaọrụ ndị a nwere ike ijigide ikike 95% mgbe usoro 1000 gasịrị, ọbụna mgbe 2000 cycles, ọ dịghị ihe na-egosi dendrite. Ndị na-eme nchọpụta na-ezubekwa ịkparịta ụka, usoro nchekwa lithium dị iche iche gbasara arụmọrụ akụrụngwa.

Anyị na-eme atụmatụ na ịzụ ahịa nke teknụzụ batrị na-agbanye elu agaghị enwe nnukwu ihe mgbochi, Jiang Bauz kwuru. Ọ bụ ezie na a na-ere graphene dị ugbu a na ọnụ ahịa dị elu, ụlọ ọrụ Angerstron Materials na-arụsi ọrụ ike na-agbasawanye ike mmepụta nke graphene. A na-atụ anya na n&39;ime afọ 1-3 na-esote, ọnụahịa mmepụta nke graphite ga-ebelata nke ukwuu.
