Table 2 Application comparison of various non-embedded temperature sensors
From: Sensing as the key to the safety and sustainability of new energy storage devices
Temperature sensor | Reference | Advantage | Disadvantage |
|---|---|---|---|
Thermocouple | [39] [40] | Accurate measurement. Wide measuring range Strong anti-interference ability | Cumbersome to use Costly Non-linear Not suitable for high volume use |
Thermistor | [41] | Low cost Wide measurement range and high sensitivity to temperature | Poor linearity Small adjustable range |
RTD | High accuracy Stability | Incompatible sensor size and battery design Slow response | |
FBG | [49] [46] [47] [48] | High sensitivity Accurate measurement Fast response time | Exposed optical fiber is fragile Needs to be packaged |
