Batteries are a very efficient energy source used in an all-digital environment that adapts to today’s human mobility. The lithium-ion battery is one of the batteries used in various household appliances. There are some problems caused by the anode in terms of utility. This is due to high electrochemical reactivity, which can reduce battery performance. One of the innovations in lithium-ion batteries is anode-free Li-ion battery (AFLB). The working mechanism of this battery is the same as the previous Li-ion battery, but with a smaller anode capacity, so that it can reduce the volume (large) of the battery. The problem that arises is the growth of dendrites that interferes with the battery’s running mechanism, so it needs to be evaluated for its growth. The way that can be done is to modify the copper foil by adding Cu. The innovation of this research is to modify Cu-foil by adding Cu from cable waste. The research method used is leaching Cu from cable waste, followed by reducing Cu powder to form a modified Cu. This study’s data collection techniques include empirical research derived from previous studies and instrumental analysis using SEM, FTIR, and electrochemical performance tests. Electrochemical testing using a cylindrical battery with a current of 1 C (1 C = 430 mA g−1) and a voltage of 2.6–4.3 V obtained ALFB and ALFB Cu-modification batteries with a discharge capacity of 70 and 123 mA h g−1, respectively. |
