Lead-acid batteries are the earliest commercialized secondary batteries, with a history of over 160 years. They use lead dioxide as the positive electrode, lead as the negative electrode, and sulfuric acid as the electrolyte, with a working voltage of 2V. Lead-acid batteries have advantages such as low cost, mature technology, and good high-rate discharge performance, Lead-Acid Batteries: Upholding Tradition While Driving Innovation

Lithium iron phosphate (LiFePO₄) batteries use lithium iron phosphate as the cathode material and carbon (graphite) as the anode material, with a nominal cell voltage of 3.2V and a charge cut-off voltage of 3.6-3.65V. Its key advantages include very high thermal stability (decomposition temperature around 600°C), long cycle life (2000-7000 cycles), excellent safety (not prone Technical characteristics of lithium iron phosphate batteries

Lithium-ion batteries achieve the conversion between electrical energy and chemical energy through the reversible migration of lithium ions between the positive and negative electrodes. During charging, lithium ions are released from the positive electrode material (e.g., LiCoO₂) and travel through the electrolyte. They pass through the separator and embed into the graphite structure of the Basic Working Principle of Lithium-ion Batteries

This is a 3D exploded-view diagram of a battery. The LiFePO₄ battery pack consists of an aluminum shell, epoxy boards​ for insulation, and a sophisticated BMS. The black part is the battery’s outer casing, providing structural support and protecting the internal components. The middle section consists of battery cells, typically connected in series or parallel via busbars to LiFePO₄ Battery Pack: A 3D Exploded View of Core Components

As a consumer searching for “robot vacuum battery selection tips,” the most important considerations are battery life, safety, and compatibility. Take the popular SMARTEC 14.8V 10AH battery as an example: it uses ternary lithium cells with an energy density of 280Wh/kg, supporting a single cleaning session for an apartment of 200㎡—far exceeding the 150㎡ limit How to Choose a Battery for a Robot Vacuum? A Beginner’s Guide for 2025

Cathode Slurry Mixing: Mix the cathode active material, conductive agent, and binder evenly to make a slurry. Anode Slurry Mixing: Using the same process, prepare a uniform anode slurry. Coating: Evenly coat the cathode and anode slurries on metal foil current collectors. Calendering: Press the electrode sheets with a heavy rollers to increase energy density.
