Highly reversible Li₂RuO₃ cathodes in sulfide-based all solid-state lithium batteries

Abstract

The practical application of high-capacity lithium-rich cathode materials in lithium-ion batteries has been largely restricted by severe side reactions with electrolytes. Herein, we report a highly stable lithium-rich Li2RuO3 cathode...

Spontaneous gas–solid reaction on sulfide electrolytes for high-performance all-solid-state batteries

“…S22, ESI †), which show gradient distribution across the interface of the LiCoO 2 /LPSC. [41][42][43] The thickness of the CEI layer measured by the EELS line scanning is roughly consistent with the HR-TEM observation. The thickness of Li 2 CO 3 layer is reduced from original 42.3 nm (Fig.…”

Synergistic Strategy Using Doping and Polymeric Coating Enables High-Performance High-Nickel Layered Cathodes for Lithium-Ion Batteries

“…Human energy consumption is rising annually as industrialization picks up speed, and the energy crisis has increasingly become the major obstacle restricting countries worldwide from achieving technological breakthroughs. − Due to the sustainability of energy transmission and distribution, electrical energy storage (EES) has gained recognition as a technology that can successfully address these challenges. Lithium-ion batteries (LIBs) are being developed increasingly in the direction of high-performance battery systems with high specific energy, high power density, high safety, and long cycle life as an emerging high-efficiency and clean energy storage device. − The cathode material, which is a crucial component of LIBs, is what primarily determines the electrochemical performance of LIBs, including energy density, cycling stability, and preparation cost.…”

The nature and suppression strategies of interfacial reactions in all-solid-state batteries

“…Our previous work has demonstrated that the uncoated LRO coupled with LPSCl exhibits excellent cycling performance (90% capacity retention after 1000 cycles), benefiting from the passivated interphase layer. 75 To further demonstrate the reliability of our calculation results, we also made a systematic comparison of the electrochemical performance of the common cathodes in combination with different types of SSEs (Table S5, ESI†). Its shows that the discharge capacity and capacity retention of cathodes coupled with LPSCl/LGPS/LPS also agrees well with our calculation results.…”
