The demand for higher performance and enriched user experience in mobile devices has steadily increased their power consumption over the past few years, a trend that rapidly outpaced the evolution of the Li-ion battery technology whose energy density simply could not keep up with the ever-increasing power demand.
The demand for higher performance and enriched user experience in mobile devices has steadily increased their power consumption over the past few years, a trend that rapidly outpaced the evolution of the Li-ion battery technology whose energy density simply could not keep up with the ever-increasing power demand.
Therefore, Li-ion battery needs to have high power density, quick charging speed and long lifetime over thousands of cycles in HEV. In comparison with HEV, batteries within PHEV could be also charged through plugging into an external electricity source. The battery here generally presents much larger capacity to enable PHEV to drive fully electric for a short …
