Peneliti Ciptakan Baterai Ponsel Anti Meledak Masih ingat kasus hebohSamsung Galaxy Note 7 yang meledak? Dikarenakan baterai yang cacat, ponsel flagship ini harus ditarik dari pasaran, dan menyebabkanSamsung rugi besar.
Sebagaimana diketahui, sebagian perangkat eletronik menggunakan baterai berjenis lithium-ion yang mudah untuk menimbulkan api.
Berkaca dari hal tersebut, para peneliti pun mencoba menciptakan sebuah terobosan.
Berkat terobosan baru yang diciptakan oleh US Naval Research Laboratory (NRL), baterai berbahan nikel-seng ternyata aman dan dapat diisi ulang.
Padahal seng (zinc) biasanya digunakan dalam baterai sekali pakai. Material tersebut biasanya tidak menjadi pilihan yang bagus untukbaterai yang dapat diisi ulang karena dapat menyebabkan hubungan pendek.
Untuk mengatasi hal itu, NRL menggunakan "spons 3D" yang ditaruh pada anoda Seng untuk mendistribusikan arus lebih merata, dan mencegah agar dendrit terbentuk.
Selain memperpanjang umur penggunaan baterai tunggal, NRL menemukan bahwa sel mereka dapat bersaing dengan baterailithium-ion selama lebih dari 100 siklus pengisian ulang.
"Kami sekarang dapat menawarkan alternatif yang relevan dengan energi. Penemuan ini dapat digunakan untuk perangkat portabel, dan kendaraan listrik," kata Jeffrey Long perwakilan NRL. (Engadget)
