Features and Benefits of Alkaline Batteries Other varieties, such as those made from nickel and cadmium, are rechargeable, though not as reliably as lithium. Most standard alkaline batteries use zinc for the anode and manganese dioxide as the cathode. As ions move from the anode to the cathode, the battery will lose voltage as it drains, and the system can’t be recharged. ![]() Some examples of products that benefit the most from lithium batteries include:Īlkaline batteries work the same as lithium models, but they only transfer ions in one direction. For example, a compact model may work well in a digital camera, while a large piece of portable medical equipment requires a larger battery solution.īecause of their consistent output, lithium batteries work best in applications where a loss of power is unacceptable. While alkaline batteries come in standard sizes, lithium batteries can be built to fit different needs. While older models can be less efficient, the electrical output should be the same whether the battery is fully charged or nearly empty. Since the lithium ions can move back and forth between both electrodes, these batteries don’t lose voltage as they work. These batteries typically have a shelf life of two to three years, regardless of how often they’re used. Unlike most alkaline batteries, lithium products can be charged and reused. Features and Benefits of Lithium Batteries When charging a lithium battery, the ions return to the anode for reuse. This transfer generates electricity until all the ions have moved from one side to the other. ![]() When the battery operates, charged lithium ions move from anode to cathode. Lithium Batteries – An OverviewĪll batteries, including lithium models, use an anode (negative terminal), cathode (positive terminal), electrolyte (conductive material), and a separator to keep the two electrodes apart. This page will break down these batteries, how they function, the advantages that they bring, and their ideal application scenarios. Before buying batteries, it helps to understand these variables so that you can make the right choice for your needs. ![]() The two most common battery types-alkaline and lithium-have some critical differences that make each better suited to specific situations. When it comes to portable energy, batteries help make the world go round.
