Tesla nyere ikike electrolyte maka sel metal lithium na-enweghị anode. Model 3 nwere ezigbo nso nke 800 km?

Na Mee 2020, ụlọ nyocha na-arụ ọrụ maka Tesla bipụtara akwụkwọ nyocha na cell metal lithium. Mgbe ahụ, ọ bịara pụta na e mepụtara electrolyte pụrụ iche nke mere ka o kwe omume ịbawanye njupụta nke mkpụrụ ndụ ma mee ka lithium dị n'ime ha guzosie ike. Ka etinyela akwụkwọ ikike ikike maka ya.

Lithium metal bụ ọdịnihu. Onye na-achịkwa ihe mejupụtara a ga-emeri.

  • Tesla Model 3 nwere ezigbo ụgbọ elu nke 770 km? Ikekwe otu ụbọchị, tupu Semi ma ọ bụ Cybertruck

Ụlọ nyocha nke Jeff Dan, otu n'ime ndị ọkachamara na-ahụ maka lithium-ion n'ụwa na-arụ ọrụ na Tesla, ebipụtala nsonaazụ nke nnwale na mkpụrụ ndụ ngwakọ. Ndị a bụ sel lithium-ion kpochapụwo, nke, agbanyeghị, graphite anode ejirikwa lithium kpuchie ya. A na-edobe igwe (metal plating, ebe a: lithium) na-ejigide ụfọdụ lithium, nke na-ebelata ikike cell. Otu electrolyte pụrụ iche gbanwere ọnọdụ ahụ.

Dahn kwuru na site na nrụgide ziri ezi, ọ nwere ike ịdọpụ ígwè ahụ na graphite, na-ekwe ka ikike cell dịkwuo elu (ebe ọ bụ na ọnụọgụ lithium atom nke nwere ike ịkwaga n'etiti electrodes). E tinyela patent maka electrolyte a..

Tesla Model 3 nwere ezigbo ụgbọ elu nke 770 km? Ikekwe otu ụbọchị, tupu Semi ma ọ bụ Cybertruck

Ma ọ bụghị naanị nke ahụ. Ọrụ nyocha egosila na Enwere ike iji electrolyte a na cell metal lithium na-enweghị anode. (nke mbụ site n'aka ekpe na foto a, AF / no anode). Ha na-enye 71 pasent karịa ikike kwa liter nke olu (1,23 kWh / L, 1 Wh / L) karịa sel lithium-ion kpochapụwo (230 kWh / L, 0,72 Wh / L), nke pụtara na na Tesla Model 720 batrị nwere ike. nabata batrị 3 kWh.

Ike a ga-ezuru iji nweta 770km nke ezigbo oke. Nke a karịrị kilomita 500 n'okporo ụzọ awara awara!

Otú ọ dị, atụla anya na Tesla ga-esi ọnwụ na ịgbasa ụgbọ ala eletrik ya dị ọnụ ala, ọbụlagodi na mbụ. Ụdị 3 bụ ugbu a onye isi ahịa na mkpuchi. Ụdị ụgbọ ala dị ogologo kwesịrị ịkpuchi ihe ruru kilomita 450 n'ezie, ebe ndị asọmpi yiri ya anaghị erute kilomita 400.

Yabụ ị nwere ike iche nke ahụ Selụ metal lithium na-enweghị anode ga-ebu ụzọ banye n'ụdị S na X maka ebumnuche nyocha, wee banye na Cybertruck na Semi.bia Model 3/Y n'ọdịnihu.

Na nke a ga-eme naanị mgbe Ụlọ nyocha ahụ ga-edozi nsogbu nke obere ọrụ ndụ nke cell metal lithium. Ugbu a, ha nwere ike idi ihe ruru 50 chaja cycles, na na ngwakọ mbipute na a lithium mkpuchi graphite anode, ruo 150 zuru arụ ọrụ cycles. Ka ọ dị ugbu a, ọkọlọtọ ụlọ ọrụ dịkarịa ala 500-1 cycles.
