Understanding Lithium-Ion Batteries

Why Are Lithium Ion Batteries Used Everywhere?

We see how the world changed in the past 30 years, and the li ion battery, which revolutionized portable power sources, is responsible for many modern advances. We witness its impact daily in technology, because over 90% of electronics use these batteries: smartphones and wearables, cars, toys, Bluetooth speakers, medical equipment – you name it. High energy density transformed device capabilities significantly. BAK Technologies is a lithium -ion battery company. ⚡

How does a Lithium Ion Battery work?

At the fundamental level, electrochemistry drives functionality. The lithium ion battery operates via ion migration. Lithium ions traverse between anode and cathode materials. This ion movement occurs during charge and discharge cycles. The anode typically uses graphite or silicon materials. The cathode comprises lithium metal oxides like LCO or NMC. 

During charging, lithium ions leave the cathode lattice. They migrate through the electrolyte to the anode. Electrons flow externally to balance the charge. This process stores electrical energy efficiently. Discharging reverses this mechanism completely. Lithium ions return to the cathode structure. Electrons flow back, delivering power to devices. 

Electrolytes facilitate ion transport internally. Separators prevent direct contact between electrodes. This approach effectively avoids dangerous internal short circuits. The design of a lithium- ion battery takes into account two main aspects that must be balanced. On one hand its the Li Ion battery performance, on the other hand – it’s safety. One of the critical aspects is material selection.
