1. A system for determining a lithium ion concentration in a lithium-containing sample, comprising:
a downhole tool, the downhole tool including:
a vessel disposed in the downhole tool, the vessel configured to contain the lithium containing sample;
one or more neutron sources configured to emit neutrons, the one or more neutron sources disposed in the vessel; and
one or more electron detectors configured to detect electrons, wherein the one or more electron detectors are arranged around a perimeter of the vessel within the downhole tool; and
a control system comprising one or more processors, wherein the control system is configured to:
determine a lithium concentration based on the electrons; and
generate a lithium extraction output based on the lithium concentration.
