Energy Capacity
Energy capacity is one of the LIB''s key performance indicators and an active area of research. The required capacity of a LIB depends on its final application (e.g. portable electronic, EVs, storage unit) [63].As shown in Table 3, only a few papers have used DoE to study the effect of electrode physical properties (e.g. thickness, volume
