Yintoni umahluko phakathi kwe-21700 kunye ne-18650?
- Ubungakanani kunye nomthamo iibhetri ze-21700 zihlulwe ikakhulu ngamacandelo amabini: iibhetri ze-lithium iron phosphate kunye neebhetri ze-ternary lithium. Iqokobhe langaphandle yi-cylinder yentsimbi enobubanzi obuyi-21mm kunye nobude obungama-70mm. Umthamo udla ngokuba ngaphezulu kwe-4000mAh. Iibhetri ze-18650 zikwahlulahlulwe ngamacandelo amabini: iibhetri ze-lithium iron phosphate kunye neebhetri ze-ternary lithium-ion. I-diameter yi-18mm, ukuphakama yi-65mm, kwaye umthamo udla ngokuba yi-2500-3600mAh.

Ubuninzi bamandla kunye nobomi bebhetri Ngokubhekiselele kubuninzi bamandla, ukuba i-21700 kunye ne-18650 ziibhetri ezenziwe ngezixhobo ezifanayo zeekhemikhali, ubuninzi babo bamandla bufana. Ngokuchasene noko, ukuba i-21700 kunye ne-18650 ayenziwanga ngemathiriyeli ekrwada yeekhemikhali ezifanayo, ukuxinana kwamandla abo kuya kwahluka. Ngokomzekelo, umthamo wamandla weyunithi yeebhetri ze-lithium iron phosphate ungaphantsi kuneebhetri ze-ternary lithium. Ngokubhekiselele kubomi bebhetri, ukuba i-21700 kunye ne-18650 iibhetri zohlobo olufanayo, ngoko iibhetri ze-21700 zinomthamo omkhulu kunye nomthamo ophezulu kuneebhetri ze-18650, kunye neebhetri ze-21700 zinokunika ubomi obude bebhetri. Ukuba i-21700 kunye ne-18650 ziintlobo ezahlukeneyo zeebhetri, ubomi babo bebhetri bunokuthi busondele ngokufanayo, oko kukuthi, iibhetri ze-18650 zisebenzisa iibhetri eziphezulu zamandla, kwaye umthamo webhetri wemveliso yabo unokuba mkhulu, mhlawumbi ube kufutshane nomthamo we-21700 iibhetri ze-lithium iron phosphate.

Iimeko zesicelo kunye nokusetyenziswa kweebhetri ze-21700 zidla ngokusetyenziswa kwizixhobo ezifuna ukugcinwa kwamandla aphezulu kunye nobomi bebhetri obude, njenge-backup ye-UPS engxamisekileyo izixhobo zombane zeenqwelo zombane kunye nezixhobo ezinkulu zombane. Iibhetri ze-18650 zisetyenziswa kakhulu kwizixhobo ezincinci ezinje ngeetotshi, izixhobo zombane ezincinci kunye nezinye izithuthi zombane.

Umahluko phakathi kwenani leeseli kunye nenani leeseli Ekubeni ububanzi bebhetri ye-21700 bukhulu kwaye bunokusingatha umthamo ongaphezulu, iqokobhe elifunekayo nge-m2 ye-21700 ibhetri yi-33% ngaphantsi kwebhetri ye-18650, ngoko ixabiso leqokobhe le-21700 ibhetri ingaphantsi kwe-18650. Ngelo xesha, ekubeni inani leebhetri ezine-Wh efanayo lincitshiswa ngama-33%, imfuno ye-injection yolwelo kunye nenkqubo yokutywinwa nayo iyancitshiswa. Kwimeko yokwenza ibhetri enkulu, ixabiso liyancitshiswa.

Izixhobo zokuqulunqa kunye nokusebenza kakuhle. Njengoko inani elipheleleyo leebhetri liyancipha, imfuno yezixhobo zokwakheka nayo iyancipha kakhulu, ephucula ukusebenza kakuhle kunye nokunciphisa iindleko. Isishwankathelo, umahluko phakathi kweebhetri ze-21700 kunye ne-18650 ubukhulu becala, ubukhulu, umthamo, ubuninzi bamandla, iimeko zesicelo, ubunzima bokuthengwa kweendleko, izindlu zebhetri kunye nobuninzi bebhetri, izixhobo zokwakheka kunye nokusebenza kakuhle, njl njl. Kubalulekile ukukhetha uhlobo lwebhetri olufanelekileyo kwiimfuno ezithile zesicelo.
