2 s/cm, between two orders of magnitude lower than the ordinary aqueous solution conductivity, this limits the lithium ion battery discharge rate.
The remedy is to use a thin electrode, from a small battery at room temperature in 2 - continuous discharge
The power of 3 c.
Compared with other high energy secondary battery, lithium ion batteries have significant performance advantages.
