6 FAQs about [Battery protection against high temperature]

How to cool batteries under high temperature conditions?

For the batteries working under high temperature conditions, the current cooling strategies are mainly based on air cooling , , liquid cooling , and phase change material (PCM) cooling , . Air cooling and liquid cooling, obviously, are to utilize the convection of working fluid to cool the batteries.

Does high temperature affect battery performance?

The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .

Why do batteries need a higher operating temperature?

The increase in operating temperature also requires a more optimized battery design to tackle the possible thermal runaway problem, for example, the aqueous–solid–nonaqueous hybrid electrolyte. 132 On the cathode side, the formation of LiOH will eliminate the attack of superoxide on electrodes and the blocking of Li 2 O 2.

How can thermal safety of lithium batteries be improved?

The thermal safety of lithium batteries is greatly improved by regulations of internal thermal-responsive components including electrolytes, separators, and cathode materials. 1. Introduction

How does temperature affect battery safety?

When temperature abnormally rises to a certain value, PTC materials rapidly transform into insulator state, cutting off the current flow to the electrode, preventing further heat generation and possible runaway reactions, which are considered promising avenues to ameliorate battery safety issues.

Why is thermal management important for lithium ion batteries?

Considering that Li–air batteries or other metal–air batteries are likely to be developed under high-temperature operating conditions (80–180°C) in the future, it is also important to tackle the thermal management issues in relation to their use to ensure the battery performance and safety.
