This pioneering battery exhibited higher energy density value up to 130 Wh kg −1 (gravimetric) and 280 Wh L −1 (volumetric). The Table 1 illustrates the energy densities of initial rechargeable LIBs introduced commercially, accompanied by the respective company names .
The maximum endurable current density of lithium battery cycling without cell failure in SSLMB is generally defined as critical current density (CCD). Therefore, CCD is an important parameter for the application of SSLMBs, which can help to determine the rate‐determining steps of Li kinetics in solid‐state batteries.
The energy density of LIBs is crucial among the issues including safety, capacity, and longevity that need to be addressed more efficiently to satisfy the consumer’s demand in the EV market. Elevated energy density is a prime concern in the case of increasing driving range and reducing battery pack size.
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
Energy is calculated by multiplying the discharge power (in Watts) by the discharge time (in hours). Like capacity, energy decreases with increasing C-rate. Cycle Life (number for a specific DOD) – The number of discharge-charge cycles the battery can experience before it fails to meet specific performance criteria.
As shown in Table 1, the current density of 35LTO35Si at 1 C is about 4 times that of 65LTO5Si for the same C-rate, which makes current density a useful parameter as opposed to the commonly used C-rate to analyze such composite electrodes. Figure 4 shows the relationship between capacity and current density for each sample.
At a current density of j eq ≈ 0.15 mA cm −2, theoretically, Li could be expected to plate out at an approximate rate of 12 nm/min (or 2.5 μAh cm −2 min −1).
