Ushbu maqolada litiy-ion akkumulyatorlarning butun hayotiy siklidagi xomashyo qazib olishdan tortib, ishlab chiqarish, foydalanish va utilizatsiyagacha bo‘lgan bosqichlardagi ekologik ta’siri tahlil qilingan. Ochiq statistik manbalar va ilmiy nashrlar asosida solishtirma issiqxona gazlari chiqindisi (kg /kW·soat), energiya sarfi hamda materiallarni qayta qoplash darajalari bo‘yicha miqdoriy hisob-kitoblar amalga oshirildi. 60 kW·soatlik elektromobil akkumulyatorini ishlab chiqarish misolida CO₂ chiqindisi va energiya balansi hisoblab chiqilgan, shuningdek, litiyni qazib olish va qayta ishlash orqali olishning solishtirma ekologik samaradorligi ko‘rsatib berilgan. Natijalar shuni ko‘rsatadiki, akkumulyatorlarni qayta ishlash xomashyoni birlamchi qazib olishga nisbatan issiqxona gazlari chiqindisini o‘rtacha 70-75% ga kamaytiradi, biroq dunyo bo‘yicha qayta ishlash darajasi hozircha past (taxminan 5-20%) bo‘lib qolmoqda.
