Anyị na-enye ntụ zirconia dị ọcha nke ukwuu, nke enwere ike iji n'ọtụtụ oge, dịka ihe cathode nke batrị lithium, nhazi TZP, ezé, azụ ekwentị mkpanaaka, ihe dị ka zirconia, n'etiti ha:

Ejiri ya mee ihe dị mma:

Ntụ ntụ zirconia nke anyị nyere nwere njirimara nke nha dị mma, nkesa nha nha otu, enweghị njikọta siri ike, na ezigbo sphericity. Ịtinye ya n'ime ihe cathode nke batrị lithium nwere ike ime ka arụmọrụ okirikiri batrị ahụ ka mma ma melite arụmọrụ ọnụego ya. Site na iji conductivity ya, enwere ike iji ntụ ntụ zirconia dị ọcha dị elu maka imepụta elektrọd na batrị siri ike dị elu. Enwere ike iji ntụ ntụ zirconia (99.99%) dị ka ihe anode maka batrị lithium, dị ka nickel cobalt lithium manganate (NiCoMn) O2), lithium cobaltite (LiCoO2), lithium manganate (LiMn2O4).

Maka ndị otu nhazi:
