The plastic ring you mentioned is really called insulating ring, which is only the outermost structure of the visible part of the whole special-shaped ring technology. One of the differences between the second generation and 1 generation lies in the improvement of the power of the second generation. By optimizing the internal structure and materials, fine graphite and zinc powder with high specific surface area are fused by high-energy anode ring, which improves the conductivity, further reduces the discharge loss, increases the effective reaction area, and realizes the improvement of electricity under the condition of constant capacity.

High-strength steel casing and high-density energy-gathering materials have also made great contributions to the overall energy-gathering of the battery. In short, the energy-gathering ring technology = energy-gathering inner ring (sealing ring+negative electrode bottom+insulating ring)+energy-gathering outer ring (three high-purity manganese rings+high purity graphite)+high-strength steel shell+high-density energy-gathering material. The upgrade of the energy gathering ring is a comprehensive upgrade of all components.

In addition to increasing the power consumption by 25%, the second-generation Fu Nan Shaped Ring used a brand-new brand of "Shaped Ring 2" battery in appearance, and the production date was changed from near the negative electrode to near the positive electrode. The words "n answer: NFU" were added to the head of the positive electrode of the battery, and the second generation shaped charge ring batteries were produced and replaced one after another from 20 18 12. The second-generation batteries of shaped charge ring are all used, so the Fu Nan batteries without lettering after the production date of 20 19 1 are fakes!
