Ndị otu Mahadum Nankai wepụtara iji usoro nhazi eji akọ rụọ ọrụ iji dozie ihe mgbochi ndị a.
**Ngwọta Ọhụrụ: g-C₃N₄ Ihe mkpuchi Carbon nwere oghere**
Ndị otu nyocha ahụ mepụtara ihe akpọrọ **CN@HCS**. Nke a na-anọchi anya graphitic carbon nitride (g-C₃N₄) nke ekpuchiri n'elu **Hollow Carbon Spheres (HCS)**.
Nhazi a bụ klaasị nano{0}} injinia:
1. **Oghere Carbon Sphere (HCS) Isi:** Na-enye nnukwu oghere maka mmekọrịta sodium{1}} ion (Na⁺) ma na-ebelata ụzọ mgbasa ion, na-eme ka chaja ngwa ngwa.
2. **g-C₃N₄ Electron{2}}Inert Layer:** Ihe mkpuchi a bụ isi ihe na-eme ka nkwụsi ike. Ọ na-arụ ọrụ dị ka ọta nhọrọ, na-egbochi mmeghachi omume akụkụ na-achọghị n'etiti electrode na electrolyte nke ọma.

Ọmụmụ ihe a na-enye nghọta miri emi n'ihe kpatara ihe a ji arụ ọrụ nke ọma:
* **Stable SEI Formation:** The g-C₃N₄ oyi akwa na-amịkọrọ nke ọma ma na-ebelata FEC (ihe mgbakwunye electrolyte nkịtị), na-akwalite nguzobe nke uwe, oke, na inorganic{1} ọgaranya Solid Electrolyte Interphase (SEI). SEI a siri ike na-eri obere electrolyte ma gbochie mmebi na-aga n'ihu.
* ** Transportgbọ njem ngwa ngwa:** Sistemụ elektrọn jikọtara ọnụ na g{{1}C₃N₄ na-enye ụzọ awara awara maka njem eletrọn na ion ngwa ngwa, na-enye ike ** dị elu -oke ọnụego**.
** Nchekwa adịghị mma: *** Mkpuchi ahụ na-ebelata ikpughe nke saịtị ntụpọ electrochemical na-arụ ọrụ n'elu carbon, na-egbochi mmeghachi omume parasitic.
**Ntụle nnwale: Otu esi eme Anode**
Maka ndị na-agụ teknuzu anyị, usoro njikọ ahụ bụ nke a:
1. ** PPy / PMMA Precursor Synthesis: ** Pyrrole monomer na a PMMA template bụ polymerized site na iji ammonium persulfate (APS) na n'okpuru 5 ogo.
2. ** HCS Synthesis:** Ihe mmalite bụ carbonized na ogo 700 na ikuku inert iji mepụta oghere carbon oghere.
3. **CN@HCS Synthesis:** A na-agwakọta HCS na urea wee kpoo ọkụ ruo ogo 500, na-eme ka urea mebie nke ọma wee mepụta ag-C₃N₄ mkpuchi n'elu oghere carbon.
