Problems solved by technology

On the one hand, when the moisture content in the battery is lower than a certain level, the electrolytic cell will be creamed or even solidified, so that it cannot provide moisture, which will end the discharge process prematurely, and the discharge capacity of the battery will be significantly reduced
On the other hand, because the moisture content is lower than a certain level, the electrolytic cell will be creamed or even solidified, which also limits the concentration of zinc powder added, thereby limiting the battery discharge capacity

Description

technical field [0001] The invention relates to the technical field of alkaline manganese batteries, in particular to an alkaline manganese battery negative electrode additive containing a wetting and dispersing agent. Background technique [0002] Alkaline-manganese battery has become the leading product in the primary zinc-manganese battery series due to its outstanding advantages such as high power, large capacity discharge characteristics, long storage period, and high performance-price ratio. With the development of the economy, various portable electronic products are constantly emerging. Electronic products such as flashlights need to be driven by a large current when they are used. The batteries used are often up to 0.5-15A, which is equivalent to a power of 0.5-2W. Improving the high-current discharge endurance has become a hot spot in the current fierce competition in the alkaline-manganese battery market. [0003] Alkaline-manganese batteries generally have the ...
