Litiyumu-ion ya batiri yimyitwarire yubushyuhe hamwe nigishushanyo mbonera cyo gucunga ubushyuhe

Hamwe no kwiyongera kugurisha no gutunga ibinyabiziga bishya byingufu, impanuka zumuriro zimodoka nshya nazo zibaho rimwe na rimwe.Igishushanyo cya sisitemu yo gucunga amashyuza nikibazo kibangamira iterambere ryimodoka nshya.Gutegura uburyo buhamye kandi bunoze bwo gucunga ubushyuhe ningirakamaro cyane mukuzamura umutekano wibinyabiziga bishya byingufu.

Li-ion ya batiri yerekana ubushyuhe ni ishingiro ryubuyobozi bwa Li-ion.Muri byo, guhererekanya ubushyuhe biranga kwerekana no kwerekana ubushyuhe buranga ibintu ni ibintu bibiri byingenzi byerekana amashanyarazi ya litiro-ion.Mu bushakashatsi buriho bwo kwerekana imiterere yo kohereza ubushyuhe bwa bateri, bateri ya lithium-ion ifatwa nkaho ifite ubushyuhe bwa anisotropique.Niyo mpamvu, bifite akamaro kanini kwiga ingaruka zimyanya itandukanye yo guhererekanya ubushyuhe hamwe nubushyuhe bwo hejuru yubushyuhe ku gukwirakwiza ubushyuhe hamwe nubushyuhe bwumuriro wa bateri ya lithium-ion kugirango hategurwe uburyo bunoze kandi bwizewe bwo gucunga amashyanyarazi ya bateri ya lithium-ion.

Akagari ka batiri 50 A · h lithium fer fosifate yakoreshejwe nkigikoresho cyubushakashatsi, kandi imiterere yimyitwarire yo kohereza ubushyuhe yasesenguwe ku buryo burambuye, maze hashyirwaho igitekerezo gishya cyo gucunga amashyuza.Imiterere y'akagari yerekanwa ku gishushanyo cya 1, kandi ibipimo by'ubunini byihariye bigaragara mu mbonerahamwe ya 1. Imiterere ya batiri ya Li-ion muri rusange irimo electrode nziza, electrode mbi, electrolyte, itandukanya, icyuma cyiza cya electrode, icyerekezo cya electrode mbi, hagati ya terefone, kubika ibikoresho, umutekano wumutekano, coefficient nziza yubushyuhe (PTC) (Ubushyuhe bwa PTC/Ubushyuhe bwo mu kirere) thermistor na bateri.Itandukanyirizo rishyizwe hagati yibice byiza nibibi bya pole, naho intangiriro ya bateri ikorwa no kuzunguruka cyangwa itsinda rya pole rikorwa na lamination.Koroshya imiterere ya selile igizwe nuburyo bugizwe nuburinganire bumwe, kandi ukore ubuvuzi bungana kubintu bya termofiziki ya selile, nkuko bigaragara ku gishushanyo cya 2. Ibikoresho bya selile ya batiri bifatwa nkigice cya cuboid gifite imiterere ya anisotropique yumuriro wa anisotropique , hamwe nubushuhe bwumuriro (λz) perpendicular yerekeza kumurongo werekeza kuba ntoya kurenza ubushyuhe bwumuriro (λ x, λy) ugereranije nicyerekezo cyo gutondekanya.
