➀ Researchers from China have proposed adding a soluble catalyst to lithium-air batteries to improve their performance and lifespan.
➁ The new imidazolyl-iodide salt (DMII) acts as a redox mediator that facilitates charge transport and prevents electrode passivation.
➂ Tests show promising results with reduced overpotential, high cycle stability, and reversible formation/decomposition of Li2O2 without side reactions.
➀ Yamaichi is developing a board-to-flexi connector for monitoring multi-cell batteries, featuring a two-part design with a push-button locking mechanism.
➁ The new Y-Lock V4 connector includes a dual-locking system with lateral hooks and a central locking mechanism for added security.
➂ The connector offers options such as gold or tin plating, a CPA lock for additional security, and various contact spacings to meet different clearance and creepage distance requirements.
➀ Researchers from KERI have developed lithium-sulphur battery prototypes with high energy density, eight times higher than lithium-ion batteries.
➁ The team used single-walled carbon nanotubes treated with oxygen to stabilize the electrodes and reduce sulfur loss.
➂ A 1000mAh prototype measuring 50x60mm retained 85% of its charge after 100 charge/discharge cycles.
➀ Researchers at TUM have developed a covalent organic framework (COF) material called 'TpBD-2F' to prevent dendrite formation and anode corrosion in zinc-ion batteries.
➁ The COF self-assembles on the surface of metallic zinc, creating a thin, porous layer that allows zinc ions to plate evenly while blocking water access.
➂ This breakthrough could enable zinc-ion batteries to replace lithium-ion batteries in large-scale energy storage applications, such as those paired with solar or wind power plants.
➀ 国际工程师和材料科学家团队开发了一种新型锂硫电池，该电池在25,000次充放电循环后仍能保持80％的充电容量。
➁ 研究人员通过设计一种具有多孔原子结构的固体硫基电极，解决了硫在充放电过程中易膨胀和离子损失的问题。
➂ 这项突破性的技术不仅提高了电池的快速充电性能，还增强了其耐用性。然而，研究人员表示还需要进一步开发以提高能量密度并探索替代材料。
