At a time when the wave of technology is sweeping the world, lithium batteries have long become the "energy code" that changes life! From mobile phones at your fingertips to electric cars, from giant energy storage power stations to precision aviation equipment, lithium batteries are everywhere, injecting surging power into modern life. ​

Lithium batteries are like "chemical elevators". Lithium ions shuttle between the positive electrode (lithium iron phosphate/ternary lithium) and the negative electrode (graphite), and electrons form current power supply through external circuits. Ternary lithium batteries have high energy density (Tesla Model S 21700 battery cells reach 333Wh/kg), which is suitable for long-range electric vehicles; lithium iron phosphate batteries are safe and durable (BYD blade batteries have more than 2,000 cycles). It is recommended to keep the power at 30%-80% on a daily basis, and shallow charging and shallow discharge can prolong life.

At the moment when new energy vehicles are popular, the accuracy of battery life directly affects the user's travel experience. As the use time increases, the battery management system (BMS) may deviate from the calculation of power, resulting in the display of battery life and actual battery life not matching. At this time, it is particularly important to calibrate the battery charge. Below, we will introduce the fast charging calibration steps and precautions for lithium iron phosphate batteries and ternary lithium batteries in detail to help you regain accurate battery life. ​

Lithium batteries are everywhere in smartphones, electric cars, and even aerospace equipment. Like an "energy heart", they drive the high-speed operation of modern technology. But have you ever wondered why this tiny battery has become a "star" in the energy industry? How does it work? What unknown secrets does it hide? Let's unveil the mystery of lithium batteries together.

In today's era of rapid technological development, lithium batteries, as a key energy storage device, have long been deeply integrated into all aspects of our lives, from daily mobile phones and laptops to electric vehicles that lead the trend of green travel, to energy storage systems that power homes. Lithium batteries are indispensable. Did you know that the lithium battery family actually has many members, and different types of lithium batteries have their own advantages in performance, characteristics and application scenarios. Today, let us go deep into the world of lithium batteries and explore the mysteries of common lithium batteries. ​

At a time when new energy technologies are developing rapidly, ternary lithium-ion batteries and lithium iron phosphate batteries, as two major mainstream technology routes, have shined in different fields with their own unique advantages.

The ternary lithium battery, also known as a lithium-ion battery, is a common type of rechargeable battery. Its working principle relies on the intercalation and deintercalation of lithium ions between the positive and negative electrodes to complete the charging and discharging process. This type of battery, due to its high energy density and good cycle life, is widely used in fields such as electric vehicles and portable electronic devices.

Lithium iron phosphate batteries, a type of lithium-ion batteries, utilize lithium iron phosphate (LiFePO4) as the cathode material, typically employ graphite as the anode, and use a combination of organic solvents and lithium salts as the electrolyte.

Ternary lithium-ion batteries have several notable advantages. They possess a high energy density, a long cycle life, and are resistant to low temperatures. However, they exhibit insufficient stability at high temperatures. Ternary lithium-ion batteries can achieve the highest energy density, but their performance at high temperatures is relatively poor. For pure electric vehicles with requirements for driving range, they are the mainstream choice, and they are also suitable for the weather in northern regions, as the batteries are more stable in low temperatures. Tesla's Model 3, which was announced, uses Panasonic's 21700 type ternary cylindrical batteries.

Ternary lithium-ion batteries and lithium iron phosphate batteries are currently two widely used types of lithium-ion batteries. They each have some advantages and disadvantages, and the choice can be made according to specific application scenarios.
