    • Advancements in 2s LiPo Battery Pack Technology: 7.4V Models Stepping up the Pace

      With the expanding market for portable electronic devices, the demand for high-performance and safe batteries is increasing. Against this backdrop, 2s LiPo (Lithium Polymer) battery packs are emerging as the focal point of the market due to their superior performance and wide range of applications. Specifically, 7.4V 2s LiPo battery packs, with their high energy density, long cycle life, and rapid charging capabilities, have garnered consumer favor.

    • What is the difference between polymer lithium battery and ternary lithium

      In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

    • Which is better between polymer lithium battery and 18650 lithium battery

      1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

    • How to make the battery safer? Industry: gradual improvement is more reliable than subversion

      According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come
