Nanga bwanji ngati titagwiritsanso ntchito mphamvu yotsala kuchokera ku mabatire otayidwa?Tsopano asayansi akudziwa momwe angachitire

Mabatire a alkaline ndi carbon-zinc amapezeka pazida zambiri zodzipangira okha.Komabe, batire ikatha, sichitha kugwiritsidwanso ntchito ndikutayidwa.Akuti pafupifupi mabatire 15 biliyoni amapangidwa ndikugulitsidwa padziko lonse lapansi chaka chilichonse.Zambiri zimathera m’malo otayirako nthaka, ndipo zina zimakonzedwa n’kukhala zitsulo zamtengo wapatali.Komabe, ngakhale kuti mabatirewa ndi osagwiritsidwa ntchito, nthawi zambiri amakhala ndi mphamvu zochepa zomwe zimatsalira mkati mwake.Ndipotu, pafupifupi theka la iwo ali ndi mphamvu 50%.
Posachedwapa, gulu la ofufuza ochokera ku Taiwan linafufuza kuti n'zotheka kuchotsa mphamvuzi kuchokera ku mabatire otayika (kapena oyambirira).Gulu lotsogozedwa ndi Pulofesa Li Jianxing wa ku Yunivesite ya Chengda ku Taiwan lidayang'ana kafukufuku wawo pankhaniyi ndicholinga cholimbikitsa chuma chozungulira pamabatire a zinyalala.
Pakafukufuku wawo, ofufuzawo apereka njira yatsopano yotchedwa Adaptive Pulsed Discharge (SAPD) yomwe ingagwiritsidwe ntchito kudziwa mayendedwe oyenera a magawo awiri ofunikira (kuthamanga kwafupipafupi komanso kuzungulira kwa ntchito) kuti:batire lotayidwa.Batiri.Mwachidule, kutulutsa kwakukulu kumafanana ndi mphamvu zambiri zobwezeretsedwa.
"Kubwezeretsanso mphamvu yotsalira yotsalira kuchokera ku mabatire apanyumba ndi chiyambi chochepetsera zinyalala, ndipo njira yowonjezera mphamvu yowonjezera mphamvu ndi chida chothandizira kugwiritsanso ntchito mabatire ambiri otayidwa," adatero Pulofesa Li, pofotokoza zifukwa za kafukufuku wake. .lofalitsidwa mu IEEE Transactions on Industrial Electronics.
Kuphatikiza apo, ochita kafukufukuwo adapanga chojambula cha Hardware cha njira yawo yomwe akufuna kubwezeretsanso mphamvu yotsalira ya batire yomwe imatha kugwira mabatire asanu ndi limodzi mpaka 10 osiyanasiyana.Anatha kupezanso mphamvu 798-1455 J ndi kuchira kwa 33-46%.
Kwa maselo oyambirira otulutsidwa, ofufuzawo adapeza kuti njira ya short circuit discharge (SCD) inali ndi chiwongoladzanja chachikulu kwambiri kumayambiriro kwa kutulutsa.Komabe, njira ya SAPD inasonyeza kuchuluka kwa kutulutsa kwakukulu kumapeto kwa nthawi yotulutsa.Pogwiritsa ntchito njira za SCD ndi SAPD, kubwezeretsa mphamvu ndi 32% ndi 50%, motero.Komabe, njirazi zikaphatikizidwa, 54% ya mphamvuyo imatha kubwezeredwa.
Kuti tipitirize kuyesa kuthekera kwa njira yomwe takambiranayi, tinasankha mabatire angapo otayidwa AA ndi AAA kuti abwezeretse mphamvu.Gululo litha kuchira bwino 35-41% ya mphamvu kuchokera ku mabatire omwe adagwiritsidwa ntchito."Ngakhale zikuwoneka kuti palibe ubwino wogwiritsa ntchito mphamvu zochepa kuchokera ku batri imodzi yomwe yatayidwa, mphamvu zobwezeretsedwa zimawonjezeka kwambiri ngati mabatire ambiri otayidwa akugwiritsidwa ntchito," anatero Pulofesa Li.
Ofufuzawo akukhulupirira kuti pakhoza kukhala mgwirizano wachindunji pakati pa kukonzanso bwino komanso mphamvu yotsala ya mabatire otayidwa.Ponena za momwe ntchito yawo idzakhudzire mtsogolo, Pulofesa Lee akuwonetsa kuti "mitundu yopangidwa ndi ma prototypes atha kugwiritsidwa ntchito pamitundu ya batri kupatula AA ndi AAA.Kuphatikiza pa mitundu yosiyanasiyana ya mabatire oyambira, mabatire omwe amatha kuchangidwanso monga mabatire a lithiamu-ion amathanso kuphunziridwa.kuti apereke zambiri zokhudza kusiyana kwa mabatire osiyanasiyana.”
