Nature Communications, (2023) 14.6407.
    Note: Extreme fast charging of Ampere-hour (Ah)-scale electrochemical energy storage devices targeting charging times of less than 10 minutes are desired to increase widespread adoption. However, this metric is difficult to achieve in conventional Li-ion batteries due to their inherent reaction mechanism and safety hazards at high current densities. In this work, we report 1 Ah soft-package potassium-ion hybrid supercapacitors (PIHCs), which combine the merits of the high-energy density of battery-type negative electrodes and the high-power density of capacitor-type positive electrodes. The full cells (1 Ah) exhibit a cell voltage of up to 4.8 V, high full-cell level specific energy of 140 Wh kg−1 (based on the whole mass of the device) with a full charge of 6 minutes. An 88% capacity retention after 200 cycles at 10 C (10 A) and a voltage retention of 99% at 25 ± 1 °C are also demonstrated.Ampere-hour-scale soft-package potassium-ion hybrid capacitors enabling 6-minute fast-charging

    Note: As healthcare technology advances, there's a growing need for implantable medical devices that are less invasive. Traditional implantable power sources are bulky and can cause issues, limiting the development of smaller devices. This work explores the history of these devices and discusses promising solutions like biodegradable batteries, energy harvesters, and wireless power transfer. These innovations aim to make implantable devices more comfortable and effective for long-term health monitoring and treatment.Minimally invasive power sources for implantable electronics

    Note: Li-CO2 batteries (LCBs) have received extensive attention as a promising alternative to solve both energy crises and CO2 emission issues. In this work, we developed a versatile on-chip electrochemical testing platform to simultaneously achieve efficient catalyst screening and in-situ probing of product chemical composition and morphology evolution of reaction products in LCBs. Following the on-chip platform results, LCB pouch cells were fabricated for practical applications. These results demonstrate the practical competitive advantages of LCBs, and more generally, the demonstrated multimodal platform can be broadly applied to other systems, thereby opening up new opportunities for rapid catalyst screening, mechanism investigation, and the development of practical applications.Developing highly reversible Li–CO2 batteries: from on-chip exploration to practical application

    Note: Solid-state lithium (Li) batteries are considered to be one of the most promising solutions for the future generation of batteries due to their excellent potential energy density and the nonflammability of solid-state electrolytes (SSEs), but the formation and propagation of Li dendrites seriously restrict their practical applications. In this work, we present a conceptual and experimental breakthrough to fundamentally overcome the inevitable dendrite propagation by introducing electronic rectifying interphase on the SSE without compromising the electrochemical reactions.Rectifying interphases for preventing Li dendrite propagation in solid-state electrolytes

    Note: Unlike traditional sensors and circuit chips sandwiched in the lens substrate, this work demonstrates an ultrathin and flexible serpentine mesh sensor layer that could be directly mounted onto a contact lens and maintain direct contact with tears, showing easy assembly, high detection sensitivity, good biocompatibility and mechanical robustness, and not interfering with either blinking or sight of vision. This multifunctional contact lens with ultrathin field-effect transistors can provide diversified signals from the eyes, providing personalised and accurate medical analysis for users. This work attracted widespread attention from the media (BBCThe TimesDaily Mail, etc.) and many investment intentions from industries. integrated contact lens sensor system based on multifunctional ultrathin mos2 transistors

    Note: This work represents a major step towards scalable intracellular recording. This is the first example of semiconductor devices showing the capability to record full amplitude intracellular action from primary neurons and cardiomyocytes, with the advantage of the device being scalable, causing less discomfort and no fatal damage to the cell (cytosol dilation). This device design also allows for multiplexed recording from single cells and cell networks and could enable future investigations of dynamics in the brain and other tissues.

    Note: This work presents the first example of a bioinspired and biomimetic brain-machine interface designed such that the key building blocks mimic the subcellular structural features and mechanical properties of neurons. It is a conceptual and experimental breakthrough that, for the first time, literally blurs the ever-present and clear dissimilarities in critical structural and mechanical properties between man-made and living systems.
