Lithium-ion polymer battery charging secrets: revealing the scientific code of the optimal voltage and current In an era when the fast charging power of smartphones exceeds 200W, people often only focus on the charging speed, but ignore the scientific logic behind the charging parameters. As the power heart of modern electronic devices, the charging management of lithium-ion polymer batteries can be called a precise human surgery - it is necessary to ensure energy delivery efficiency and maintain battery health. This article will deeply analyze the setting principle and practical value of its optimal charging parameters. I. Charging voltage: the electrochemical code behind 4.2V The standard charging termination voltage of lithium-ion polymer batteries is 4.2V±0.05V, and this value is determined by the physical limit of the electrode material. The crystal structure of the positive electrode lithium cobalt oxide (LiCoO₂) will collapse irreversibly when it exceeds 4.25V, ...
