The key to enabling long-term cycling stability of high-voltage lithium (Li) metal batteries is the development of functional electrolytes that are stable against both
Thus, a large amount of batteries is required to reach 200–300 miles driving range. As the energy densities of LIBs head toward a saturation limit, 2 next-generation batteries (with energy densities >750 Wh/L and >350 Wh/kg) that are beyond LIBs are needed to further increase driving range more effectively.
Here, a phase-shifted full-bridge (PSFB) converter with a current doubler rectifier and a voltage multiplier circuit for lithium-ion batteries is proposed. By

Abstract: The need to increase the charging speed of lithium-ion (Li-ion) battery energy storage systems (BESS) has led to the usage of high-voltage (HV) battery packs in e-mobility applications. External short-circuits (ESCs) might lead to high current rates far
Improving the rate capability of lithium-ion batteries is beneficial to the convenience of electric vehicle application. The high-rate charging, however, leads to lithium inventory loss, mechanical effects and even thermal runaway. Therefore, the optimal charging algorithm of Li-ion batteries should achieve the shortest charging interval with
In the past few decades, most researchers have focused on improving the ionic conductivity of SEs and prolonging the long cycle life of solid-state lithium metal batteries (SSLMBs). However, a high-voltage-stable electrolyte is essential, because the energy density (E g) of the batteries is determined by the following equation: E g = V ×
