Wanem samting i narakain namel long wanpela 'lithium' na 'alkaline' bateri?
Mi kisim wanpela kol las winta long wanpela 'procurement manager' long wanpela 'cold storage' operesen long Wisconsin. Em i bin lusim 8-pela envairomen monitoring sensa bikos long bagarap bilong bateri, na em i bel hevi bikos em i no inap painimaut wanem samting i bin rong. Tim bilong em i bin yusim ol Duracell ProCell alkalines, na ol i bin ranim wanpela kwata riplesmen sediul we i mas i stap gut inap. Ol i bin skelim ol sensa bilong ol bateri, ol i bin raitim ol taim bilong lukautim ol samting, na olgeta samting i luk stret long pepa.
Hevi em i tempereja. Long -18 digri, we em i standet bilong putim ol ais samting, ol alkaline bateri i no save wok olsem ol datasit bilong ol i tok. Kapasiti i go daun long ating 10-20% bilong mak, na taim ol 'alkaline cells' i stap nating long ol ples we i kol, ol i save lik. Potassium hydroxide electrolyte i bin kaikaim ol 'sensor contacts' insait long sampela wik. Long taim wanpela i opim ol yunit bilong mekim wok mentenens, 'corrosion' i go insait long ol 'circuitry'. Olgeta lus, klostu long $12,000.
Em i bin mekim matematiks long ol yunit kos, sekim ol 'compatibility specs', bihainim olgeta nomol step bilong kisim samting. Nogat wanpela bilong ol dispela i kamapim hevi bilong tempereja bikos nogat wanpela man i tingim long askim long kol pefomens taim ol i baim ol AA bateri.
Dispela toktok em i as na mi raitim dispela. Difrens namel long 'lithium' na 'alkaline' i no hat long sait bilong kemistri, tasol ol 'performance implications' i stap aninit long 'generic comparison content' we i no helpim wanpela man long mekim ol disisen bilong baim samting.

Kwikpela tok klia
Sapos yu nidim wanpela kwik bekim: ol 'lithium battery' i gat bikpela pe pastaim tasol i save givim moa pawa taim yu putim planti samting long en, i wok long taim bilong kol, i save stap longpela taim long stoa na i no gat 'leak', na i no gat bikpela pe long olgeta taim sapos yu yusim ol bateri long bikpela volium. Ol 'alkaline battery' i no gat bikpela pe long wanpela yunit na i wok gut long ol masin we i no gat planti wara long en insait long ol ples we i gat gutpela klaimet we yu no save ron long en oltaim.
Longpela vesen i involvim long kliagut long as na ol dispela samting i narapela na wanem taim ol i bikpela samting long ol spesifik aplikesen bilong yu. Planti bilong ol rong bilong baim samting mi lukim i kamap taim ol i putim rongpela kain bateri long wanpela yus kes we ol wiknes bilong en i kamap ples klia.
Kapasiti Aninit long Lod: We Trupela Difrens i kamap
Planti taim ol i save skelim ol bateri na ol i save lukluk long 'energy density' na 'voltage'. Ol dispela namba i bikpela samting, tasol ol i no ples we ol kampani i save lusim mani long en. Hevi we i save afektim ol opereting kos em hamas bilong 'rated capacity' yu ken yusim aninit long 'current draw' bilong divais bilong yu.
Wanpela alkaline AA sel i gat mak bilong 3000mAh. Dispela mak i kam long 'discharge testing' long liklik 'current', planti taim 25mA o liklik. Ol 'hanheld scanner' we planti haus kago i save yusim i save pulim 500-800mA. Ol tu-wei redio i save pulim wankain o antap moa. Long 800mA discharge, dispela 3000mAh alkaline sel i save givim samting olsem 1000mAh bilong eneji we yu ken yusim. Yu baim wanpela kapasiti we yu no inap long kisim.
As bilong dispela em i 'internal resistance'. Wanpela nupela 'alkaline cell' i gat 'internal resistance' klostu long 0.15Ω, we i liklik inap long i no bikpela samting. Tasol 'alkaline chemistry' i gat wanpela pasin we ol i no save toktok planti long en insait long ol wok bilong baim ol samting: 'internal resistance' i go antap taim sel i lusim. Long taim yu yusim 90% bilong 'theoretical capacity', 'internal resistance' i go antap long 0.75Ω o moa. Aninit long bikpela 'current draw', dispela 'resistance' i save senisim bikpela hap bilong eneji i stap yet i go long hat na i no gutpela autput. Bateri i no dai long tingting olsem em i pinis; em i dai pinis long wanem em i no inap long givim karent long gutpela voltej moa.
Litiam kemistri i no gat dispela hevi long wankain mak. Intenel resistens i stap gut long taim bilong 'discharge cycle', we i min olsem wanpela 3500mAh litiam sel i save givim klostu long 3500mAh maski yu pulim 100mA bilong wanpela rimot kontrol o 2A bilong wanpela pawa tul.
Mi bin wok wantaim wanpela distribusen senta las yia we i bin wok long stretim ol hevi bilong ol Zebra TC52 skena we i no wok gut inap planti mun. Spec sheet i tok 8-aua rantaim, ol i kisim 3-pela aua, na olgeta i ting olsem i gat samting i no stret wantaim hardware. Em i kamap olsem ol 'scanner' i orait. Ol 'alkaline' bateri aninit long lod i no save givim 'rated capacity' bilong ol. Ol i senisim i go long Li-ion we yu ken sasim gen, na ol wankain skena i stat long paitim 7+ aua. Difrens i stap long ol bateri.
Pefomens bilong Tempereja
Dispela em i samting we i mekim kampani bilong Wisconsin i kirap nogut, na ating em i samting we ol i no tingim tumas long makim ol bateri bilong ol indastrial aplikesen.
Long rum tempereja, tupela alkaline na lithium i wok klostu long mak bilong ol. Taim tempereja i go daun, spes i op bikpela tru. Alkaline kemistri i save pilim kol tru bikos ol 'electrochemical reactions' i save go daun na 'internal resistance' i save go antap moa yet. Long 0 digri, yu lukluk long 50-70% bilong mak bilong kapasiti. Long -18 digri, we em i wanpela komon setpoint bilong 'frozen storage', 'alkaline' i save holim ating 10-20% kapasiti-i no gat wok long planti aplikesen. Long -40 digri, em i zero tru.
Lithium i holim 70-80% kapasiti long -18 digri na i save givim 50-60% long -40 digri. Ol tes we ol i pablisim long backpackinglight.com i soim olsem 'alkaline' i save stap inap 25 minit long 0 digri F aninit long wankain lod kondisen we 'lithium' i save stap inap 150 minit. Em i 6-pela taim i narapela long 'real-world runtime' long 'temperature' tasol, maski i gat hevi bilong 'capacity-under-load'.
As tingting bilong en: sapos yu wok long ranim ol 'cold chain logistics', ausait infrastraksa, 'refrigerated transport', o wanpela 'facility' long wanpela noten klaimet we ol ikwipmen i ken stap long ples we i kol tru, ol 'alkaline battery' em i no wanpela rot bilong sevim mani. Ol i wanpela hevi bilong 'reliability' we bai kamapim moa mani long ol bagarap, ol imejensi senis, na ol bagarap bilong ol ikwipmen winim ol yunit prais sevings.
Narapela sait tu em i gutpela long tok: sapos yu wok long ol ples we i gat gutpela klaimet na ples i no hat tumas namel long 15-30 digri, bai yu no inap lukim gutpela bilong 'cold tolerance' bilong 'lithium' na i no gat as long baim.
Total Kost bilong Onasip
Ol yunit prais skelim em we planti bateri i save go rong long en. Matematik i luk klia-alkaline AAs i kost $0.50-1.00, ol 'rechargeable lithium equivalents' i kost $5-10, bilong wanem wanpela man bai baim 10× moa long ol bateri?
Long wanem, pe bilong wanwan yunit em i no samting yu baim long taim bilong diploimen.
