摘要
采用Li Ni1/3Co1/3Mn1/3O2作为正极材料,石墨为负极材料,制成18650型/1300 m A·h功率型圆柱电池;该类电池5 C放电容量相当于1 C放电容量的99%,5 C循环测试900次后,容量剩余87%以上;经过针刺后,电池没有起火爆炸。
The 18650/1300 mA＆#183;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.
