  • Publication number: 20240429459
    Abstract: Improved battery separators are disclosed herein for use in various lead acid batteries, and in particular lead acid battery strings. The improved separators, batteries, battery strings, methods, and vehicles disclosed herein provide substantially increased battery life, substantially reduced battery fail rate, and substantially higher voltage uniformity among the various batteries in a battery string. The improved battery strings may be advantageously employed in high depth of discharge applications such as electric bicycles, golf carts (or golf cars), uninterrupted power supply (UPS) backup power battery strings, and the like.

  • Patent number: 11761063
    Abstract: Disclosed is a method for preparing a high-entropy alloy composites reinforced by diamond particles, belonging to the technical field of metal composites preparation. A vacuum coating preparation equipment equipped with an in-situ heating sample stage is used to perform a treatment of high-entropy alloy metallizing coating on the surface of diamond particles to generate modified diamond particles, where the alloy of the coating includes any four, five or six elements among seven elements of Ti, Zr, Hf, Nb, Ta, W and Mo in an equal atomic proportion. The obtained coating generates carbide film in-situ with the surface layer of diamond particles, while the high-entropy alloy covers the carbide film, ensuring a strong bond with the diamond, and the high-entropy alloy composites reinforced by diamond particles are finally prepared.

  • Patent number: 11299433
    Abstract: A manufacturing method of a low heat-conducting magnesium-aluminium spinel brick includes: (1) evenly mixing sintered magnesia, fused magnesia, magnesium-aluminium spinel and corundum to prepare flame retardant coating raw material mixed powder, adding naphthalene binder to the flame retardant coating raw material mixed powder to prepare the flame retardant coating raw materials after evenly mixing; (2) evenly mixing forsterite, fayalite and magnesia, adding the naphthalene binder to the mixed powder, moulding, drying, and then burning to obtain aggregate composite hortonolite raw materials; adding the naphthalene binder to the aggregate composite hortonolite having granularity ?5 mm to prepare the thermal insulating layer raw materials after evenly mixing; (3) spacing and loading the flame retardant coating raw materials and the thermal insulating layer raw materials in a mold, pressing into green bricks, keeping the green bricks at a temperature of 110° C.
