Maitiro ekuwedzera simba density ye lithium-ion bhatiri 1. Ramba uchivandudza iyo yakanaka electrode zvinhu kune anogamuchira zvinhu (giramu rekuchengetedza simba) mune yakanaka chiitiko chechinhu chinoshanda chinokwanisa. Muchiitiko apo huwandu hwehuwandu hwezvinhu zvakanaka zvinoshanda zvinogara, iyo chete nhamba yepamusoro ye lithium ions inogona kuparadzaniswa kubva kune yakanaka electrode ye thermochemical reactions, nokudaro inogara ichivandudza simba remagetsi.

Naizvozvo, chiyero chekugara kwechigadzirwa cheinobvisirwa lithium ions chakakwira kupfuura chiyero chekugara kwechigadzirwa cheyakanaka electrode inoshanda zvinhu, uye kunaka kwechigadzirwa kugara kweiyo yakanaka electrode inoshanda zvinhu yakakwira kupfuura indekisi yekuchengetedza. 2. Kugara uchiwedzera huwandu hweanode zvinhu chinhu chakajairika.

Haisi budiriro huru musimba rekuchengetedza simba reiyo dynamic lithium ion bhatiri, asi kana ichiwedzera kuvandudza cathode ratio kuchengetedza, anode zvinhu, lithium, inomiririra kunaka kwechigadzirwa, lithium Ions inogona kugarisa zvakanyanya uye zvakanyanya, kuvandudza simba density inoramba ichivandudza. 3. Chinangwa chakakosha chekuenderera mberi nekuvandudza kugara kwezvinhu zvakanaka zvinoshanda Ramba uchiwedzera mugove wezvinhu zvinoshanda mu electrode yakanaka ndeyekuramba uchiwedzera chikamu che lithium.

Mune imwecheteyo bhatiri kemikari indasitiri michina, kuumbwa kwe lithium kunowedzera nyowani (mamwe mamiriro anodiwa asina kuchinjika), uye iyo simba density inogara ichiwedzerwa. Naizvozvo, pasi pehumwe vhoriyamu uye huremu hwakazara, iwe unoda kuve nezvakawanda zvinoshanda zvinhu, zvakawanda. 4.

Convergence yekuwedzera chikamu chezvinhu zvinoshanda muiyo negative electrode Iyi dhizaini ndeyekufananidza zvirinani zvinhu zvine magetsi zvinoshanda, uye zvinowedzera zvisina kunaka zvemagetsi zvinoshanda zvinhu kuti zvigadzirire zasi kwerukova lithium ions kuchengetedza kinetic simba. Kana pasina zvakakwana zvinhu zvinoshanda mu electrode yakaipa, yakawandisa lithium ions inodonha uye yakaturikidzana pamusoro peiyo negative electrode, pane kupinda mukati me electrode. Inverse thermochemical reaction uye bhatiri kushaya simba zvinowanzoitika.
