Lithium metal batteries (LMBs) comprising Li anode and high-voltage cathode could exhibit high capacity and power density. However, stable electrolytes to tolerate the oxidation on the cathode at high cut-off voltage are urgently needed. Herein, we present an armor-like inorganic-rich cathode electrolyte interphase (CEI) strategy for exploring oxidation-resistant electrolytes for sustaining 4.8 V Li||LiNi0.6Co0.2Mn0.2O2 (NCM622) batteries with pentafluorophenylboronic acid (PFPBA) as the additive. In such CEI, the armored lithium borate surrounded on CEI up-layer represses the dissolution of inner CEI moieties and also improve the Li+ conductivity of CEI while abundant LiF is distributed over whole CEI to enhance the mechanical stability and Li+ conductivity compared with polymer moieties. With such robust Li+ conductive CEI, the Li||NCM622 battery delivered excellent stability at 4.6 V cut-off voltage with 91.2% capacity retention after 400 cycles. The excellent cycling performance was also obtained even at 4.8 V cut-off voltage.

Armor-like Inorganic-rich Cathode Electrolyte Interphase Enabled by Pentafluorophenylboronic Acid for High-voltage Li||NCM622 Batteries.

The application of solid polymer electrolytes (SPEs) in all-solid-state(ASS) batteries is hindered by lower Li+-conductivity and narrower electrochemical window. Here, three families of ester-based F-modified SPEs of poly-carbonate (PCE), poly-oxalate (POE) and poly-malonate (PME) were investigated. The Li+-conductivity of these SPEs prepared from pentanediol are all higher than the counterparts made of butanediol, owing to the enhanced asymmetry and flexibility. Because of stronger chelating coordination with Li+, the Li+-conductivity of PME and POE is around 10 and 5 times of PCE. The trifluoroacetyl-units are observed more effective than -O-CH2-CF2-CF2-CH2-O- during the in-situ passivation of Li-metal. Using trifluoroacetyl terminated POE and PCE as SPE, the interfaces with Li-metal and high-voltage-cathode are stabilized simultaneously, endowing stable cycling of ASS Li/LiNi0.6Co0.2Mn0.2O2 (NCM622) cells. Owing to an enol isomerization of malonate, the cycling stability of Li/PME/NCM622 is deteriorated, which is recovered with the introduce of dimethyl-group in malonate and the suppression of enol isomerization. The coordinating capability with Li+, molecular asymmetry and existing modes of elemental F, are all critical for the molecular design of SPEs.

Influencing Factors on Li-ion Conductivity and Interfacial Stability of Solid Polymer Electrolytes, Exampled by Polycarbonates, Polyoxalates and Polymalonates.

Building better solid‐state batteries with silicon‐based anodes

Alloy-type anodes are one of the most promising classes of next-generation anode materials due to their ultra-high theoretical capacity (2~10 times that of graphite). However, current alloy-type anodes have several limitations: a huge volume expansion, a high tendency to fracture and disintegrate, an unstable solid-electrolyte interphase (SEI) layer, and low Coulombic efficiency. Efforts to overcome these challenges are ongoing. This review details recent progress in the research of batteries based on alloy-type anodes and discusses the direction of their future development. We conclude that improvements in structural design, the introduction of a protective interface, and the selection of suitable electrolytes are the most effective ways to improve the performance of alloy-type anodes. Furthermore, future studies should direct more attention toward analyzing their synergistic promoting effect.

Alloy-type Anodes for High-performance Rechargeable Batteries.

Power batteries are a crucial component of electric vehicles and other electric equipment. Their long-term high-rate discharge generates a lot of heat, which can lead to battery failure, shortened battery life, and even safety accidents if not managed properly. Due to its high thermal conductivity, the heat pipe can quickly conduct heat away from the battery and separate the heat source from the heat sink. In addition, due to its excellent isothermal performance, the heat pipe can also achieve the characteristics of low-temperature preheating and high-temperature cooling of the power battery by reducing the inhomogeneity of the battery temperature field to reduce the temperature difference. In this paper, we review the current state of the art in thermal management of automotive lithium-ion battery, and highlight the current state of thermal management of batteries based on the combination of nanofluids and heat pipes. Finally, the development of nanofluidic heat pipes in lithium-ion battery heat management systems is prospected.

This article mainly analyzes the ice slurry cold storage system in solar refrigerated vehicles, calculates and studies the thermal properties of the ice slurry, the cold load of the refrigerated vehicle, and the solar photovoltaic panels, and calculates the fuel savings of using solar power generation. Study the demand for ice slurry in ice slurry storage systems under different energy utilization efficiencies, analyze the economy of solar ice slurry generation systems, and calculate the recovery period of the system in this paper. The daily power generation of solar photovoltaic panels can run the electric motor for 2.93 hours. The solar refrigerated truck can save 7.91 liters of oil per day and reduce carbon dioxide emissions by 1.25×107 liters per day. The average annual electricity cost savings are 4026.67 CNY. Based on the total cost of the photovoltaic energy storage hybrid quality system, it will take 3.89 years to recover the cost. Calculate the density and enthalpy of the ice slurry based on the thermophysical model of the ice slurry, and provide different utilization amounts for the ice slurry mass generated by the ice slurry generation system at different efficiencies. Calculate the total weight of the ice slurry system.
