6 FAQs about [Battery energy loss]

How is energy lost in a battery?

A portion of the energy is either lost through the inevitable heat generation during charge/discharge or retained as irreversible electrochemical energy in the battery through parasitic chemical/electrochemical reactions of electrolyte and formation of side products.

What causes battery losses?

Battery losses are due to several factors, among which are undesired electrochemical reactions within a battery, bad battery condition management by a battery management system (BMS), and cell warming due to internal resistance . Accounting for such losses from a theoretical point of view is beyond the scope of this paper.

How does battery degradation affect EV operation?

The battery degradation causes gradual increasing of battery internal resistance and decreasing of battery charging/discharging efficiency, which results in increasing of unit energy consumption and GHG emissions during EV operations.

What happens to battery energy at the end of life?

The battery energy at the end-of-life depends greatly on the energy status at the as-assembled states, material utilization, and energy efficiency. Some of the battery chemistries still can have a significant amount of energy at the final life cycle, and special care is needed to transfer, dispose of, and recycle these batteries.

What is the energy eficiency of a battery?

Figure 1. Evolution of the energy of various types of batteries at the statuses of as-assembled, maximum charge, and recycling/disposal (fully discharged after reaching 80% capacity retention). energy input of a battery is the energy eficiency.

What happens if a battery is degraded?

Besides, the battery degradation will also lead to required battery replacement, which will add 88.9 GJ equivalent of energy and 5760 kg CO 2,eq GHG emissions (Supplementary Figures 4, 5) based on a cradle-to-gate analysis of a 24 kWh LMO–graphite battery pack 35, 36, 37.
