Description

¿79Û9542~8 10 15 20 25 aktiva massan Z hållas åtskilda från varandra med hjälp av en separator 3 av mikroporös polypropenfilm och av ett glas- fiberskikt 4, som innehåller elektrolyten.
Cellens totaldimensioner är en höjd av 2,5 mm och en diameter av ZS mn.Den aktiva ytan är approximativt 3 cmz.
Den positiva aktiva massan har följande sammansättning: Kopparvismutat (Bi2Cu04) 77 % Polytetrafluoreten 4 % Blypulver (inert elektronisk ledare) 19 % Mängden aktiv massa är 1,2 gram, vilket teoretiskt mot- svarar 363 mAh. Mängden litium väljes att teoretiskt mot- svara 400 mAh. Elektrolyten utföres av en 2 M lösning av litiumperklorat i dioxolan. p På detta sätt konstruerade celler har utsatts för ur- laddning genom en resistans på 100 ohm, vilket utgör ett strängtitestvillkor.
I fig. 2 visas urladdningskurvan för en cell av detta slag, varvid urladdningen C (i mAh) är avsatt utefter ab- skissan och cellens klämspänning V (i volt) utefter ordinatan. fSåsom framgår av figuren erhålles 313 mAh om urladdningen stoppas vid en spänning om 1,2 volt. Cellen har således en verkningsgrad av 86 %, Uppfínningen är givetvis inte begränsad till den ovan beskrivna utföringsformen. Speciellt förtjänar att påpekas, att den med föreliggande aktiva material försedda cellen kan ha någon annan, lämplig konfiguration. linux
