Imec: peb muaj cov khoom siv hluav taws xob electrolyte, lub zog tshwj xeeb 0,4 kWh / liter, them 0,5 ° C

Lub Belgian Imec tau khav theeb tias nws muaj peev xwm tsim cov khoom siv hluav taws xob electrolyte nrog lub zog ntom ntom ntawm 0,4 kWh / liter uas tuaj yeem them tus nqi ntawm 0,5 C. Rau kev sib piv: 21700 (2170) lithium-ion hlwb siv hauv Tesla Model 3.Reach txog 0,71 kWh / liter thiab tuaj yeem them rau lub sijhawm luv luv nrog lub zog siab dua 3 C.

Thaum lub roj teeb tsis zoo dua li Panasonic ua rau Tesla, kev tshaj tawm tau txhawb nqa. Cov hlwb imec muaj cov khoom siv-state nanocomposite electrolytes (qhov chaw). Lawv muaj kev nyab xeeb dua thaum muaj xwm txheej thiab yuav tsum tso cai rau koj kom ua tiav lub zog them nyiaj ntau dua yam tsis muaj kev cuam tshuam pom. Yam tsawg kawg hauv kev xav.

Ntawm lub zog ceev ntawm 0,4 kWh / L, qhov them nyiaj yuav tsum yog 0,5 ° C, uas yog ib nrab ntawm cov roj teeb muaj peev xwm (20 kW rau 40 kWh, thiab lwm yam). Ntawm no, cov chaw tsim khoom kuj xav kom muaj kev txhim kho tseem ceeb hauv xyoo tom ntej. Lub tuam txhab npaj kom ncav cuag 2 ° C nrog kev nce ntxiv ntawm lub zog tshwj xeeb txog 1 kWh / l. Thiab hauv 2024 nws xav kom ncav cuag qhov ceev ntawm 3 C.

Xws li lub zog nyob rau hauv classical lithium-ion hlwb suav hais tias siab heev thiab siv rau lub sijhawm luv luv. Twb tau 2 ° C zoo li qhov tsim nyog txwv, saum toj no cov cell decomposition accelerates.
