What's the Difference between Alkaline Batteries and Lead Carbon Batteries? Alkaline battery definition and application Alkaline battery is also known as alkaline battery, alkaline zinc-manganese battery, and alkaline manganese battery, which is the best performance variety among zinc-manganese batteries. It is applicable for large discharge capacity and long-term use. The internal battery resistance is low, so the current generated is greater than general manganese batteries, and environmentally friendly type only contains 0.025% mercury, no recycling. Main advantage of alkaline battery The main advantage of alkaline battery is durable power, which is usually seven times as the normal battery. In addition, the initial response time is short, making it most suitable for the camera flash. Stable output and there is no leakage. Therefore, some advanced electronic products such as BP machines, remote controls, and electronic cameras are stipulated to use vinnic alkaline battery. Alkaline batteries are generally marked with "non-rechargeable" words, this is for security reasons. Lead carbon battery production principle Lead carbon battery is a capacitor-type lead-acid batteries, which adds activated carbon in lead-acid battery negative electrode. The positive electrode active material of common lead-acid battery is lead oxide (PbO2), and the negative electrode active material is lead (Pb), if replace all of the negative electrode active material Pb with active carbon, the ordinary lead-acid batteries will turn into a hybrid capacitor; if mixed the activated carbon in the Pb anode active material, then the ordinary lead-acid batteries will become lead carbon batteries.
Features of Lead carbon batteries In terms of performance, lead-acid batteries have both carbon battery and capacitor characteristics. The adding of activated carbon enhances the power density of the battery and prolongs the cycle life, and because the activated carbon electrode occupies some space, the lower energy density is reduced, and may also increase the parsing volume of the electrode. In the process, the adding of activated carbon increases the mixing and the pole piece coating difficulty. Overall, lead-carbon battery performance is better than ordinary lead-acid battery, which is an advanced lead-acid battery, and is also the mainstream development direction of the lead-acid battery technology. Carbon batteries have a broad application prospect Carbon batteries are the most advanced technology of lead-acid batteries, and are development focus of new international energy storage industry, which has a very broad application prospect. Lead-carbon batteries, lithium ion batteries and flow battery are three development directions of new energy storage batteries. Among them, the cost of lithium is relatively high, consistency problems still exist; flow battery cost is also high; while lead carbon batteries are relatively practical storage technology roadmap recently. Ordinary lead-acid battery has the low cost advantage, but its drawback of short life cycle results in higher cost of storage per unit. Lead-carbon batteries prevent salinization of the negative phenomena due to the addition of activated carbon, extending battery life, but also reduces the unit cost of using energy storage, which has great development potential in the new energy storage field.
