Ảnh hưởng của polyethylene glycol (PEG) đến hiệu suất của vật liệu cực dương LiMn2O4 cho pin lithium ion
Tóm tắt
Giai đoạn spinel LiMn2O4 được tổng hợp bằng phương pháp đồng kết tủa có sự hỗ trợ của polyethylene glycol (PEG). Các mẫu được đặc trưng bằng các kỹ thuật nhiễu xạ tia X và kính hiển vi điện tử quét. Các mẫu LiMn2O4 được tổng hợp có hình thái tương tự và kích thước đồng đều khoảng 150–350 nm. Các phép đo điện hóa cho thấy mẫu nanoparticle LiMn2O4 được tổng hợp sử dụng PEG có trọng lượng phân tử là 4000 (PEG-4000) cho thấy hiệu suất chu kỳ tốt nhất và khả năng tỷ lệ cao nhất trong số tất cả các mẫu, với dung lượng phóng ban đầu là 133 mAhg−1 và duy trì ở mức 122 mAhg−1 ở 0.5 °C sau 50 chu kỳ. Mất mát dung lượng chỉ là 5,1%. Kiểm soát kích thước hạt của LiMn2O4 là một trong những yếu tố quan trọng cho ứng dụng của nó như một vật liệu cực dương.
