채용 LiNi1/3Co1/3Mn1/3O2작위정겁재료，석묵위부겁재료，제성18650형/1300 mA·h 공솔형원주전지；해류전지5 C 방전용량상당우1 C 방전용량적99%，5 C 순배측시900차후，용량잉여87%이상；경과침자후，전지몰유기화폭작。
The 18650/1300 mA·h Li-ion batteries were prepared with LiNi1/3Co1/3Mn1/3O2 as positive electrode and graphite as negative electrode. The discharge capacity of the batteries at 5 C was about 99% of the capacity obtained at 1.0 C. The capacity was over 87% of the original capacity after 900 cycles. Furthermore, there was no exploding and fire when the batteries were short circuited by puncturing.
