The capacity of the 21V lithium battery is 5000 mAh.
The rated current of the 21V lithium battery is 5000mA. When the 21V lithium battery is charged with a charger, the input current is higher than its rated current, between 5000-6500mA. When the 21V lithium battery discharges, the output current is lower than the rated current, which is between 4500 and 50 O0 mA, so the current of the 21V lithium battery is between 4500 and 6 500mA.
Battery overview
Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Cell phones and laptops use lithium-ion batteries, commonly known as lithium batteries. Batteries generally use lithium-containing materials as electrodes and are representative of modern high-performance batteries. Real lithium batteriesum are rarely used in daily electronic products due to their high risk.
Lithium-ion batteries were first developed by the Japanese company Sony Corporation in 1990. It integrates lithium ions into carbon (petroleum coke and graphite) to form a negative electrode ( traditional lithium batteries use lithium or lithium alloy as the negative electrode). The commonly used cathode materials are LixCoO2, LixNiO2 and LixMnO4, and the electrolyte is LiPF6 + diethylene carbonate (EC) + dimethyl carbonate (DMC).
Petroleum coke and graphite are used as negative electrode materials, which are non-toxic and have sufficient resources. Lithium ions are integrated into carbon, which overcomes the high activity of lithium and solves the safety problems of traditional systems. Lithium batteries. The LixCoO2 positive electrode is chargedand discharged. The performance and service life can reach a higher level, which reduces the cost. In short, the overall performance of lithium-ion batteries is improved. Lithium-ion batteries are expected to occupy a significant market in the 21st century.
