oyi na-emetụta batrị steeti siri ike?

otú oyi si emetụta batrị steeti siri ikena ihe a na-eme maka ya:

Gịnị mere oyi bụ ihe ịma aka

1. Obere ion conductivity

   • Ndị electrolytes siri ike (ceramics, sulfides, polymers) na-adabere na ion lithium na-agbapụ site na kristal siri ike ma ọ bụ ihe owuwu polymer.

   • Na obere okpomọkụ, nke a hopping slows ala, otú ahụesịtidem mgbochi na-abawanyena nnyefe ike dara ada.

2. Nsogbu interface

   • Na batrị steeti siri ike, kọntaktị dị n'etiti electrolyte siri ike na electrodes dị oké mkpa.

   • Okpomọkụ oyi nwere ike imebi ihe na ọnụego dị iche iche, na-ekeobere ogherena interfaces → na-eme ka ion na-asọba njọ.

3. Nchaji siri ike

   • Dị ka batrị lithium-ion mmiri mmiri, na-ebufe n'ihe egwu dị oke alalithium plating(lithium ọla na-akpụ na anode).

   • Na steeti siri ike, nke a nwere ike ịka njọ ebe ọ bụ na dendrites (nkedo lithium dị ka agịga) nwere ike ịgbawa electrolyte siri ike.

Tụnyere lithium-ion oge niile

• Lithium-ion nke mmiri electrolyte: Oyi na-eme ka mmiri dị ukwuu (na-adịghị eduzi), na-ebelata oke na ịgba ụgwọ ọsọ.

• Lithium-ion siri ike: Nke dị nchebe na oyi (enweghị mmiri oyi na-agbapụta / na-agbapụta), manaka tụfuru conductivityn'ihi na ihe siri ike anaghị ebuga ion nke ọma na obere oge.

Ihe ngwọta dị ugbu a na nyocha

1. Sulfide electrolytes

   • Ụfọdụ electrolytes siri ike dabere na sulfide na-eme ka arụmọrụ dị elu dị elu ọbụna n'okpuru 0 Celsius.

   • Na-ekwe nkwa maka EV na mpaghara oyi.

2. Polymer-seramiiki ngwakọ

   • Ijikọta polymers na-agbanwe agbanwe na irighiri seramiiki na-eme ka ion na-erugharị na obere oge na-echekwa nchekwa.

3. Injinia interface

   • A na-emepụta akwa mkpuchi ma ọ bụ ihe nchekwa iji mee ka kọntaktị electrode-electrolyte kwụsie ike n'oge okpomọkụ na-agbanwe.

4. Sistemụ ikpo ọkụ tupu EV

   • Dịka EV nke taa na-ekpo ọkụ batrị mmiri tupu ịchaji, EVs steeti siri ike n'ọdịnihu nwere ike iji.njikwa okpomọkụidobe mkpụrụ ndụ n'ọnọdụ dị mma (15-35 Celsius C).

Nchịkọta:
Oyi na-emetụta batrị steeti siri ike n'ezie, ọkachasị n'ihi nrụpụta ion dị ala yana nguzogide interface. Ha ka dị nchebe karịa lithium-ion mmiri mmiri n'ọnọdụ ndị ahụ, manaarụmọrụ (oke, ọnụego ụgwọ, mmepụta ike) nwere ike ịdaba nke ọma n'okpuru 0 Celsius. Ndị na-eme nchọpụta na-arụsi ọrụ ike na electrolytes na atụmatụ ndị na-adịgide adịgide n'oge oyi, na-achọ maka ojiji a pụrụ ịdabere na ya na EV ọbụna n'oge oyi.
