Lithium cells charge-discharge rate

Two electrochemical lithium/carbon cells were made for each of the pyrolyzed materials. We used currents of 18.5 mA/g (20-hour rate) for the fust three charge-discharge cycles and 37 mA/g (10-hour rate) for the extended cycling test. 

The characteristics of the 50-Ah LTO cell from Altaimano used in the fast charging tests are given in Table 3.6. The cell had a resistance of about 0.9 mO resulting in a Cr value of 0.045, which is typical for lithium cells, but not particularly low for an LTO cell (see Table 3.2). The Ah capacity of the cell varied little with discharge rate up to 6C. Based on the test results in Section 3, it is reasonable to expect that the 50-Ah cell would have good fast charging characteristics.
