A LIB is an electrochemical device that stores/delivers electrical energy through a reversible intercalation reaction in which Li+ ions are shuttled between two dissimilar electrode materials separated by the Li+ ion conducting electrolyte solution.

Solar Cell vs. Solar Panel

• Solar Cell: One individual PV unit (~0.5V)

• Solar Panel: Many cells connected in series/parallel

Charging Details

• Charge with CC/CV method (constant current, then constant voltage)

• Max voltage per cell: 4.2V

• Common charge rate: 0.5C–1C (C = cell capacity)

Example: 18650, 2500mAh → safe charge current = 1.25A to 2.5A
