Lid-Asid Batri Pozitiv Ilɛktrod Aktiv Matirial ɛn Ripa Mɛtɔd: Wan Kɔmplit Gayd

1. Lid-Asid Batri Pozitiv Aktiv Matirial: Prɔpati ɛn Rol fɔ Lid Dayɔksayd (PbO2)

1.1 Kɔmpozishɔn ɛn Strukchɔ

Lid dayɔgzayd (PbO2) na di praymar aktv matirial fɔ di pɔzitiv ilɛktrɔd in batri dɛn we gɛt lid-asid . Na dak brawn sɔlid wit tu men kristal fɔm dɛn:

α-PbO2 (Orthorhombic) : I gɛt wan dense strɔkchɔ, we de gi lɔng bateri layf bɔt rili wik dischaj pefɔmɛns.

β-PbO2 (Tetragonal): I de sho hכy riaktiviti εn bεtε dischaj pεrformεns bכt i de mכr pron fכ sכft εn shed, we na kכmכn fεil mכd na batri.

1.2 Ilɛktrokɛmikɛl Riakshɔn Mɛkanism

di chaj εn dischaj prכsεs dεm na di positifu εlektrod involv rivεrsibl kεmikכl riakshכn dεm:

Dischaj (Ridyushɔn): .

PbO2 + SO22 + 4H+ + 2e− → PbSO2 + 2H2O

Chaj (Ɔksidɛshɔn): .

PbSO4 + 2H2O → PbO2 + SO22 + 4H+ + 2e−

Dɛn riakshɔn ya de ɔnda di bateri in ɛnaji stɔrɔj ​​ɛn rilis.

1.3 Di men tin dɛn we pɔsin kin du

di hכy כksidayzin Abiliti: PbO2 na strכng כksidayzεr εn i nid asid invayroment (sכlfyurik asid εlektrolayt) fכ stebul.

Prone to Shedding: Volyum chenj we yu de saikl de mek di aktif matirial sof ɛn shed, we kin mek di kapasiti lɔs ɛn di bateri nɔ wok.

Poor Conductivity: PbO2 insɛf gɛt limited ilɛktrik kɔnduktiviti, so i de dipen pan lid-bɛs grid alɔy (lid-kalsiɔm ɔ lid-antimoni) fɔ ilɛktron kɔndukshɔn ɛn mɛkanikal sɔpɔt.

1.4 Failure Modes ɛn Ripa Chalenj dɛn

Softening/Shedding: Bɔku tɛm, i nɔ kin chenj, i kin nid fɔ chenj di bateri ɔ plet.

Sulfation: fכmeshכn fכ kכs PbSO4 kristכl dεm we de inkrεs intanεt rεsistεns; pat pan di ripa de posbul tru disulfation mεtכd dεm.

Ripa Limitations: Bɔku tɛm, siriɔs pɔsitiv ilɛktrɔd damej kin nid fɔ riples di bateri bikɔs i nɔ kin izi fɔ mek di aktiv matirial intɛgriti kam bak.

2.2 Praktikal Ripa Mɛtɔd dɛn

Fizik Ripa (Sɔlfeshɔn, Wata Lɔs):

Men wan fɔ di wata we dɔn flɔd batri dɛn we gɛt lid-asid lɛk batri dɛn we de stat motoka. Chek ɛn rifil ilɛktrɔlayt lɛvɛl wit Lid-Asid Batri Rɛstɔrɔshɔn Sɔlwɛshɔn, klin di sɔlfeshɔn dipɔsit dɛn jisnɔ, dɔn du kɔntrol chaj/dischaj saykl fɔ mek di kapasiti kam bak.

Pulse Disulfayshɔn: .

Yuz ay-frikyuɛnsi ilɛktrik puls fɔ brok dɔŋ lid sɔlfɛt kristal dɛn. Rikways spɛshal puls disulfator ikwipmɛnt we mach to bateri vɔlɔt. If yu yuz am pasmak, dat kin pwɛl di plet dɛn, so i fayn fɔ tek tɛm.

Di tin dɛn we dɛn kin yuz fɔ ad di tin dɛn we dɛn kin yuz fɔ mek kemikal:

If yu ad tin dεm we de sכlv sכlfεt lεk EDTA כ sכdiכm sכlfεt i kin εp fכ sכlv sכlfεt. Bɔt if yu nɔ yuz am di rayt we, dat kin mek di plet dɛn rɔtin ɛn i kin mek di batri layf shɔt.

Dip Sayklin fɔ Mild Sɔlfeshɔn:

Dischaj di bateri to lɛk 10.5V (fɔ 12V bateri), dɔn du slo chaj na 0.1C fɔ 12+ awa, ripit 2-3 saykl fɔ mek di kapasiti yɔŋ bak.

Ilɛktrolayt Riplesmɛnt:

Fɔ kɔntamin ɔ ol, dreyn ol ilɛktrɔlayt, rins wit distil wata, ful-ɔp bak wit fresh ilɛktrɔlayt (spɛsifi k graviti 1.28–1.30), ɛn richaj. Best suited fɔ di wan dɛn we wata dɔn flɔd batri dɛn we gɛt lid-asid.
