The working principle of a lithium-ion battery is shown in the diagram below
In the discharge process, the anode (Anode) loses electrons while the lithium ions migrate from the electrolyte to the cathode (Cathode). Conversely, there is a charging process. The charging and discharging process is a process of de-lithiuming and embedding lithium. This is why lithium-ion batteries, also commonly known as rocking-chair batteries, are used.
Graphite as the negative electrode
lithium cobaltate as the positive electrode "lithium battery" electrode materials negative electrode materials are divided into three categories.
(1) Insertion-responsive negative electrodes are typically represented by graphite and lithium titanate.
(2) Alloy reaction type anode
3) Transformation-responsive anodes mainly include metal oxides, metal sulphides, etc.
Common cathode materials include laminates and spinel structured materials.
Due to the demand for high specific capacity batteries, ternary cathode materials have become the focus of attention.
When charging "Li-ion batteries", care should be taken: doing so at the right multiplier will help extend the battery life.
Lithium batteries" have had a huge impact on our daily lives.
The electronic devices we have today are inseparable from lithium-ion batteries, and the new electric vehicles are partly powered by lithium-ion batteries. The safety and stability of lithium-ion remains the most important research hot issue, and how to avoid the accident of the Samsung mobile phone is a work in progress for some time to come.
