48V 20ATernary lithium batteryThe weight is approximately 17 kg.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912.
In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.
Early R&D
Lithium batteries were first used in pacemakers. Lithium batteries present the frontsages an extremely low self-discharge rate and gentle discharge voltage, allowing pacemakers implanted in the human body to work for a long time without recharging. Lithium batteries typically have a voltage rating above 3.0 volts and are best suited for use as an integrated circuit power supply. Manganese dioxide batteries are widely used in calculators, digital cameras and watches.
In order to develop more efficient varieties, various materials were researched to create unprecedented products.
In 1992, Sony successfully developed lithium-ion batteries. Its practicality has significantly reduced the weight and volume of portable electronic devices such as cell phones, laptops and calculators.
The weight is approximately 30 to 45 kg.
The energy density of the Li batteryCurrent ternary polymer thium is 150-200 WH per kilogram, so the weight of ternary lithium battery is 30-40 kg if it is lithium iron phosphate battery. The energy density of lithium iron phosphate battery is smaller, only 135 WH per kilogram, so the weight of lithium iron phosphate battery should be 45 kilograms.
