Electrical and structural studies of lithium-ion battery (original) (raw)

Lithium ion batteries are lifeline for consumer electronic devices and large scale batteries are grown rapidy for e-mobility, renewable energy, stationary and energy storage solutions due to its superior electrochemical characterstics,multiple chemistries and design as well. Hence, this paper discuss the electrical properties of 18650 cylindrical type of lithium-ion battery for different Crates at ambient temperature. The electrical test results showed that the capacities are found to be 96% and 98.6% for the Crates at 1.0C and 0.1C respectively. The performance of the Lithium-ion battery is closely related to the chemistry of the cathode. The structural studies on the cathode materials were carried out by X-ray diffraction. The structural analysis confirmed the cathode chemistry is lithium cobalt oxide and the electrical results correlated and discusssed to understand safety level of the lithium-ion battery.
