A uniform and high-voltage stable LiTMPO₄ coating layer enabled high performance LiNi_0.8Co_0.15Mn_0.05O₂ towards boosting lithium storage

Abstract

LiTMPO4, such as LiNiPO4, can maintain structural stability and Li+ transport activity up to 4.8 V, showing great potential to stabilize layered nickel rich cathode at high voltage. But how...

Converting a Commercial Separator into a Thin‐film Multi‐Layer Hybrid Solid Electrolyte for Li Metal Batteries

“…Second, the anode and cathode themselves are modified by applying coatings on the Li metal to improve electro-deposition/dissolution to form an artificial solid electrolyte interphase (SEI), or by applying thin coatings on the cathode material to protect the electrolyte or cathode material from degradation by forming an artificial cathode electrolyte interphase (CEI). [25][26][27][28][29][30][31][32][33][34][35] These approaches require an additional coating process by means of atomic layer deposition (ALD), sputtering, casting, or chemical deposition of the electrodes. Therefore, an alternative third SE multi-layer approach has attracted attention recently.…”

“…However, these bulk electrolyte modifications are mainly for a specific purpose and often lack synergetic multifunctional applications. Second, the anode and cathode themselves are modified by applying coatings on the Li metal to improve electro‐deposition/‐dissolution to form an artificial solid electrolyte interphase (SEI), or by applying thin coatings on the cathode material to protect the electrolyte or cathode material from degradation by forming an artificial cathode electrolyte interphase (CEI) [25–35] . These approaches require an additional coating process by means of atomic layer deposition (ALD), sputtering, casting, or chemical deposition of the electrodes.…”
