리튬 배터리에 대한 차가운 지식 공개: 휴대전화부터 우주까지, 세상을 어떻게 바꿀까? Posted by batterymanufactory.com
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. Application King Electric vehicles: 2025 Zeekr 001 has a range of 1,032 kilometers, and NIO ET7 semi-solid-state batteries support 1,000 kilometers + battery replacement, and a range of 550 kilometers at minus 20℃. Energy storage field: In 2024, the scale of China's electrochemical energy storage market will be 266.1 billion yuan...
