Nano-germanium muaj qhov zoo ntawm qhov sib txawv ntawm qhov nqaim, siab nqus coefficient, thiab kev txav siab. Thaum siv rau cov txheej txheem nqus ntawm lub hnub ci, nws tuaj yeem nthuav dav qhov nqus ntawm infrared band spectrum ntawm lub hnub ci hlwb.

Germanium tau dhau los ua cov khoom lag luam tsis zoo tshaj plaws rau cov roj teeb lithium-ion vim nws lub peev xwm theoretical siab.

Lub peev xwm theoretical ntawm germanium yog 1600 mAh / g, thiab lub ntim muaj peev xwm siab li 8500 mAh / cm3. Tus nqi diffusion ntawm Li + hauv Ge cov khoom yog kwv yees li 400 npaug ntawm Si, thiab cov khoom siv hluav taws xob yog 104 npaug ntawm Si, yog li germanium yog qhov tsim nyog rau cov khoom siv hluav taws xob tam sim no thiab lub zog siab.

Txoj kev tshawb no tau npaj cov khoom siv nano-germanium-tin/carbon composite. Cov khoom siv carbon tuaj yeem txhim kho cov conductivity ntawm germanium thaum hloov mus rau nws qhov ntim hloov. Qhov sib ntxiv ntawm cov tin tuaj yeem txhim kho cov conductivity ntawm cov khoom. Tsis tas li ntawd, ob lub ntsiab lus ntawm germanium thiab tin muaj peev xwm sib txawv rau lithium extraction / insertion. Cov tivthaiv uas tsis koom nrog cov tshuaj tiv thaiv tuaj yeem siv los ua cov matrix los tsis cuam tshuam qhov hloov pauv ntawm lwm cov khoom siv thaum lub sij hawm tus nqi thiab cov txheej txheem tawm, yog li txhim kho cov qauv kev ruaj ntseg ntawm qhov tsis zoo electrode.
