Ib qho kev piav qhia ntawm Lithium Polymer roj teeb thiab yuav ua li cas lawv tau dhau los ua ib qho chaw siv roj teeb.

Cov roj teeb lithium-ion tau nyob ib puag ncig 40 xyoo thiab lawv tseem sawv cev rau cov kev xaiv nrov tshaj plaws ntawm cov roj teeb hauv ntau txoj hauv kev, los ntawm smartphones mus rau lub tsheb fais fab. Lithium muaj cov khoom uas ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov, tab sis ib qho downside yog tias nws tsis pom zoo kom nqus tau thiab yuav tsum muab pov tseg kom zoo. Ib txoj hauv kev zoo tuaj yeem yog lithium polymer roj teeb uas muaj kev nyab xeeb dua, tus phooj ywg ib puag ncig, thiab tuaj yeem ua nrog cov sib xyaw sib txawv dua li cov lithium-ion ib txwm muaj. Cov hom tshiab ntawm cov roj teeb no yuav nthuav tawm xyoo 2020 rau lub tsheb hluav taws xob tab sis yuav zoo li yuav pib nthuav dav thoob plaws kev lag luam los ntawm 2025.

Tam sim no, cov roj teeb lithium ion yog qhov kev xaiv nrov tshaj plaws rau kev lag luam kev lag luam vim tias lawv yog:

1. Lub zog siab tshaj plaws ntawm txhua lub roj teeb rechargeable.

2. Lub teeb hnyav heev thiab me me muab lawv lub peev xwm. Piv txwv li, lub roj teeb smartphone hnyav 20g tab sis muaj peev xwm ntawm 6Ah thiab 1000mAh. 3. Muaj peev xwm raug them rau ntau txoj kev (xws li, xaim, hnub ci) yog li kev them nyiaj ntau yam 4. Muaj lub zog siab tshaj plaws lub ntsiab lus lawv tuaj yeem muab cov dej ntws siab thaum tseem tuav tau qhov tsim nyog voltage 5. Lub neej ntev - nws yuav siv li 400- 500 cycles kom ncav cuag 50% muaj peev xwm

Txawm li cas los xij, muaj qee qhov tsis zoo thiab:

1. Chemistry thiab kev tsim khoom tau kim heev.

2. Lawv tsis yog ib puag ncig zoo vim yog cov pov tseg uas muaj tshuaj lom uas lawv tsim nrog rau lawv cov pov tseg.

3. Lawv tsis muaj cov ntaub ntawv kev nyab xeeb zoo piv rau cov roj teeb ib txwm muaj - lawv ntes hluav taws yooj yim dua, lawv tawg, thiab lwm yam.

4. tuaj yeem raug puas tsuaj tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv sib sib zog nqus tawm cycling - tam sim ntawd poob rau hauv voltage tuaj yeem rhuav tshem lawv.

5. Cov khoom siv hluav taws xob yog cov nplaim taws hauv lawv daim ntawv qhuav thiab tawg hauv lawv daim ntawv anode.

6. Lawv tsis tuaj yeem them rov qab zoo li lithium ion roj teeb

Txawm li cas los xij, cov roj teeb tshiab no tuaj yeem hloov pauv txhua yam los ntawm:

1. Ua los ntawm cov ntaub ntawv muaj kev nyab xeeb (lithium hlau phosphate thiab lithium sulfur)

2. Siv txoj kev ruaj ntseg ntawm kev tsim khoom - lub cathode yog tsim los ntawm polymer es tsis txhob siv hlau thiab nws muaj nyob rau hauv cov ntaub ntawv yas kom muaj kev nyab xeeb ib puag ncig rau lub roj teeb (ceeb toom: qhov no kuj txhais tau tias nws tuaj yeem siv tau sai dua li li-ion tsoos. roj teeb)

3. Muaj lub zog tsawg heev - 30-45Wh / kg piv rau 200Wh / kg rau cov roj teeb li-ion tsoos

4. Muaj peev xwm tsawg heev - 0.8-1Ah/kg piv rau 5-10Ah/kg rau cov roj teeb li-ion tsoos

5. Muaj lub zog tsawg heev - 0.01Wh / kg piv rau 5Wh / kg rau cov roj teeb li-ion tsoos

6. Ua tus phooj ywg ib puag ncig: lub cathode yog ua los ntawm hlau phosphate uas tuaj yeem siv tau thiab cov electrolyte yog ib qho eco-friendlier version ntawm lithium polymer.
