Lithium (Li)-ion batteries will play a key role in the electrification of transport, including electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). However, the present energy storage of Li-ion batteries cannot meet the requirements of transportation in terms of driving range and safety. As a kind of potential alternative energy storage devices, rechargeable Li-air batteries have become one of the most attractive candidates for energy storage and EVs. Li-air batteries can provide several times higher energy density/specific energy of the existing battery systems. In this paper, we mainly focus on the research status, especially some progresses made in our lab, existing challenges and their solutions as well as perspective on the future directions on lithium-air batteries.
Lithium-ion betri ni moja ya vifaa vya umeme vya umeme katika sekta ya usafiri, na pia katika sekta ya umeme ya umeme (PHEVs). Hata hivyo, kuhifadhi nishati ya sasa ya Li-ion betri haiwezi kukidhi mahitaji ya usafiri katika suala la kuendesha gari mbalimbali na usalama. Kama aina ya uwezekano mbadala ya kuhifadhi nishati vifaa, rechargeable Li-Air betri kuwa moja ya wagombea kuvutia zaidi kwa ajili ya kuhifadhi nishati na EVs. Li-hewa betri inaweza kutoa mara kadhaa juu ya nishati wiani / nishati maalum ya mifumo ya betri zilizopo. Katika karatasi hii, tunazingatia hasa hali ya utafiti, haswa maendeleo fulani yaliyofanywa katika maabara yetu, changamoto zilizopo na suluhisho zao, na vile vile mtazamo juu ya mwelekeo wa baadaye wa betri za lithiamu-hewa.
