The Analysis Of Capabilities At The Ex-Laptop 18650 Lithium Ion Battery

Abstract

The lithium ion battery has Lots used in device electronics, including laptops. However, as time goes by, the performance battery can decrease. Battery the often thrown away and become a problem environment Because own substances are dangerous and challenging to unravel. A more environmentally friendly and economical choice if we can reuse it in various projects. This study aims to The Analysis of Capabilities at The Ex-Laptop 18650 Lithium Ion Battery. This research method is descriptive research, namely carrying out current investigations that solve existing problems, namely carrying out observations, data collection and measurements on 18650 lithium-ion batteries. The results measuring the highest battery capacity are 2.015 AH, and the lowest battery capacity is 0.031 AH with an average capacity of 1.063 AH. In contrast, the internal resistance is 16 mΩ to 125 mΩ, with an average of 41.55 mΩ. Lithium-ion 18650 batteries used for laptops experience a decrease in capacity and resistance in use and recharge cycles, contributing to battery capacity degradation.
