A critical review of thermal issues in lithium-ion batteries

Do lithium-ion batteries have thermal issues?

In this paper, a critical review of the available literature on the major thermal issues for lithium-ion batteries is presented. Specific attention is paid to the effects of temperature and thermal management on capacity/power fade, thermal runaway, and pack electrical imbalance and to the performance of lithium-ion cells at cold temperatures.

Do lithium-ion batteries need thermal management?

Finally, this leads to recognition of critical gaps in lithium-ion battery thermal management research, which are not filled by current thermal management strategies. The performance, life, and safety of lithium-ion batteries are all affected by their operation and/or storage temperatures.

How does temperature affect a lithium ion battery?

Both the higher and lower temperature environments will seriously affect the battery capacity and the service life. Under high temperature environment, lithium-ion batteries may produce thermal runaway, resulting in short circuit, combustion, explosion and other safety problems.

Do temperature and thermal management affect lithium-ion cell performance?

Specific attention is paid to the effects of temperature and thermal management on capacity/power fade, thermal runaway, and pack electrical imbalance and to the performance of lithium-ion cells at cold temperatures. Furthermore, insights gained from previous experimental and modeling investigations are elucidated.

Why do lithium ion batteries have a high temperature sensitivity?

Benefits of cooling technology Lithium-ion batteries have much temperature sensitivity. The optimum range of operating temperature for battery operation is close to about 15°C to 35°C . However, due to high current loading conditions such as fast charging or accelerations, the transient battery can experience unacceptable temperature rise.

How to choose a thermal management system for a lithium ion battery?

The proper choice of thermal management system is essential for LIBs, considering factors such as battery size, lifespan, and charge and discharge rates. Advances in new materials, such as nanometer PCMs, and advanced cooling and heating techniques are improving the efficiency and safety of these systems.
