Vesainzi vakagadzira masero e-sodium-ion (Na-ion) ane electrolyte yakasimba • ELECTRIC CARS

26.05.2022 /

Masayendisiti kubva kuYunivhesiti yeAustin (Texas, USA) vakagadzira masero eNa-ion ane electrolyte yakasimba. Ivo havasati vagadzirira kugadzirwa, asi vanotaridzika vachivimbisa: vakafanana mune mamwe maitiro kune lithium-ion maseru, anomira mazana akati wandei ekushanda uye anoshandisa chinhu chakachipa uye chinokwanisika - sodium.

Asphalt, graphene, silicon, sulfur, sodium - izvi zvinhu uye zvinhu zvichaita kuti zvikwanise kuvandudza zvinhu zvemagetsi mune ramangwana. Vane chinhu chimwe chete vakafanana: ivo vari nyore kuwanikwa (kunze kwegraphene) uye vanovimbisa kuita kwakafanana, uye pamwe zviri nani mune ramangwana, lithium.

Pfungwa inonakidza ndeyekutsiva lithium ne sodium. Zvese zviri zviviri zviri muboka rimwechete remarata ealkali, ese ari maviri akaenzana, asi sodium ndiyo yechitanhatu kuwanda kwechikamu chepasi uye tinogona kuiwana zvakachipa. Mumaseru eNa-ion akagadzirwa muTexas, lithiamu iri muanode inotsiviwa nesodium, uye maelectrolyte anopfuta anotsiviwa nesodium sulfur electrolytes. (kunobva).

Pakutanga, cathode yeceramic yakashandiswa, asi panguva yekushanda (kugamuchira kubhadharisa / kutengesa kutengesa) yakashandura saizi uye yakaputsika. Naizvozvo, yakatsiviwa necathode inoshanduka yakagadzirwa neorganic zvinhu. Sero rakagadzirwa nenzira iyi rakashanda pasina kukundikana kweanopfuura mazana mana ekuchajisa / kubuda, uye iyo cathode yakagamuchira simba density ye 400 kWh / kg (ukoshi uhwu haufanirwe kuvhiringidzwa nehuwandu hwesimba hwesero yese kana bhatiri).

> Tesla Robotaxi kubva 2020. Iwe enda unorara uye Tesla anoenda uye anokugadzirira mari.

Mushure mekuwedzera kwekuvandudzwa kwecathode, zvakakwanisika kusvika pachiyero che 0,587 kWh / kg, iyo inenge inoenderana nemaitiro akawanikwa pamakateti e lithium-ion masero. Mushure memazana mashanu ekuchajisa, bhatiri rakakwanisa kubata 500 muzana yekugona kwayo.iyo inowiriranawo nemiganhu ye [isina simba] Li-ion masero.

Masero eNa-ion anoshanda pamhepo yakaderera pane masero e-lithium-ion, saka anogona kushandiswa kugadzira magetsi anotakurika. Nekudaro, boka reAustin rakafungawo kuenda kune yakakwira voltage kuitira kuti maseru ashandiswe mumotokari dzemagetsi. Sei? Chimwe chezvikamu zvikuru zvemotokari isimba rayo, uye zvakananga zvinoenderana nesimba rezvino uye magetsi pamagetsi.

Zvakakodzera kuwedzera kuti John Goodenough, muvambi we lithium-ion masero, anobva kuYunivhesiti yeAustin.
