Key direct health indicators include State of Health (SOH), Coulomb efficiency (CE), and charging/discharging times (CCCT/CVCT). These metrics provide insights into how well a battery retains charge over time and its overall efficiency during operation.
Based on the material density of a lithium battery, Kushnir and Sandén (2012) estimate that 200 g of lithium per kWh of battery capacity is a reasonable approximation of lithium required in current designs for BEV batteries. With progress, 160 g of lithium per kWh may be a reasonable medium term estimate (Kushnir and Sandén, 2012). Currently
Lithium-ion batteries should not be charged or stored at high levels above 80%, as this can accelerate capacity loss. Charging to around 80% or slightly less is recommended for daily use.

Generally, lithium-ion batteries become vulnerable to thermal runaway at temperatures above 80°C (176°F). Once this threshold is crossed, the risk of chemical reactions leading to thermal runaway increases significantly. Understanding this temperature limit is crucial for safe battery design and usage.
