Stalling oxygen evolution in high-voltage cathodes by lanthurization

Mingzhi Cai et al.

Summary: This study develops a theory to address the oxygen loss and degradation of high-energy-density cathodes in lithium-ion batteries, and proposes a lantharizing process to regulate the near-surface structure of energy materials. Surface passivation, suppressed degradation, and improved electrochemical performance are demonstrated using LiCoO2 as an example. The high-voltage cycling stability has been greatly enhanced, up to 4.8 V versus Li+/Li, including in practical pouch-type full cells.

A tough Janus-faced CEI film for high voltage layered oxide cathodes beyond 4.6 V

Yinping Qin et al.

Summary: In this study, a novel CEI film with high-voltage stability and ultrahigh Young's modulus was constructed by adsorbing SN on electrode particles and electrochemically polymerizing CHB. This film not only prevents electrolyte decomposition and irreversible phase transition on particles surface, but also suppresses particles cracking and Co element dissolution. The cyclic performance of LiCoO2 and LiNi0.8Co0.1Mn0.1O2 cathodes is significantly improved.

Oxygen framework reconstruction by LiAlH4 treatment enabling stable cycling of high-voltage LiCoO2

Pengfei Wang et al.

Summary: By developing a one-step wet chemical coating method at room temperature, this study successfully stabilizes the interface of LiCoO2 under high voltage and achieves excellent cycling performance. The treated commercial samples show a capacity retention of 70.4% even after 1000 cycles. The key to the improvement in electrochemical performance lies in restraining the loss of lattice oxygen, which is effectively achieved by the Al-containing composite layer that stabilizes the interface structure of LiCoO2.

Tailoring electrolyte to enable high-rate and super-stable Ni-rich NCM cathode materials for Li-ion batteries

Fangyuan Cheng et al.

Summary: The study shows that detrimental effects on the electrochemical performances of high-capacity nickel-rich layered oxide cathode LiNi0.8Co0.1Mn0.1O2 can be limited by forming a uniform inorganic/polymer cathode-electrolyte interface (CEI) through in-situ electrochemical oxidation of trace dual additives in traditional carbonate-based electrolytes. This CEI film not only eliminates adverse cathode-electrolyte interface reactions and prevents electrolyte penetration into grain boundaries, but also inhibits the formation of inactive rock salt phase on the material surface.
