Summary: The study focuses on estimating the future demand for battery metals, such as lithium, cobalt, nickel, and manganese, for the production of electric vehicle battery cathode raw materials. The results indicate that by 2040, the future demand for lithium, cobalt, and nickel for Lithium-Ion Batteries in electric vehicles will exceed current raw material production. The recycling potential for lithium, nickel, and cobalt is more than half of the raw material demand in 2040, indicating the industry's need to scale up resource production and prioritize the recycling of battery metals.

Summary: Mono-solvent DMC electrolyte is used for the first time in contact prelithiation, and the low-organic-content REI formed by this electrolyte is found to be a mixed ion/electron conductor. As a result, electron channels can be maintained even when the Li source is completely wrapped by the DMC-derived REI, leading to outstanding Li source utilization and negligible dead Li yield.

Summary: This article investigates the effect of low-frequency positive pulsed current (PPC) charging on the lifetime and charging performance of Li-ion batteries. Experimental results show that compared to traditional constant current (CC) charging, Li-ion batteries cycled by PPC charging have improved lifetime, maximum rising temperature, and energy efficiency by 81.6%, 60.5%, and 9.1% respectively. Therefore, low-frequency PPC charging should be considered as a promising charging strategy for Li-ion batteries.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
