Efficient Operation - The Preferred Material For Extending Battery
Life: Phase Change Materials For 45℃ Batteries
Product Introduction:
- 45℃ battery special phase change material is a kind of functional
material specially designed and developed for battery thermal
management system. It is mainly composed of substances with
specific phase transition temperature properties, and its core
phase transition temperature is precisely set at about 45°C.
- At room temperature, it exhibits a specific physical form and
chemical stability. When the battery generates heat during charging
and discharging, causing the temperature to rise to 45°C, the phase
change material will rapidly undergo phase change.
- For example, from solid to liquid, in the process of absorbing a
lot of heat, so as to effectively prevent the battery temperature
from further climbing, to avoid the battery due to overheating and
performance decline, shorten life and even cause serious problems
such as thermal runaway.
- When the temperature of the battery is reduced, the phase change
material in the liquid state will reverse phase change back to the
solid state, releasing the heat stored before, playing a certain
role of insulation, so that the battery is maintained in a more
suitable working temperature range, reducing the adverse effects of
low temperature caused by the battery charging and discharging
efficiency, internal resistance increase and so on.
Product advantages:
1. Precise temperature control
- It can accurately absorb or release heat at about 45°C, so that the
battery is always kept in a relatively stable operating temperature
range, and avoid adverse effects on battery performance due to too
high or too low temperature.
- For example, high temperature leads to shortened battery life and
reduced performance, and low temperature reduces battery charging
and discharging efficiency, effectively extending the service life
of the battery.
2. Efficient energy storage
- During the phase transition process, it can absorb or release a
large amount of latent heat, and the energy storage density is
large. Compared with traditional sensible heat storage materials,
it can store more heat under the same volume or mass, so as to
achieve efficient heat storage and release, which helps to improve
energy utilization efficiency and reduce energy waste.
3. High security
- When the battery temperature reaches 45°C, the phase change
material will actively absorb the heat of the battery cell,
preventing the battery temperature from further rising, reducing
the risk of thermal runaway of the battery.
- When the battery damage temperature is momentarily too high, the
phase change material can also absorb a lot of heat into liquid
state, prevent the battery from fire, explosion and other
accidents, and provide a more reliable safety guarantee for the use
of the battery.
4. Passive thermal management
- No additional power components or complex control system to drive
its work, relying on its own phase change characteristics can
achieve the adjustment of battery temperature, system structure is
simple, low cost, and reliable operation, reducing the complexity
and cost of battery thermal management system.
5. Improve battery performance consistency
- The temperature of each cell in the battery string is more uniform,
reducing the temperature difference, improving the performance
consistency of the battery string, avoiding the overall battery
string performance degradation caused by the temperature
inconsistency of the battery string, and improving the charging and
discharging efficiency and output power of the battery string.
Product application scenarios:
1. Thermal management of power battery
- In the power battery pack of electric vehicles, 45℃ battery special
phase change materials can be used to maintain the operating
temperature of the battery.
- When the battery generates heat in the charge and discharge
process, and the temperature rises to 45°C, the phase change
material undergoes a phase change to absorb heat, prevent the
battery from overheating, avoid problems such as shortened battery
life, reduced performance and thermal runaway caused by high
temperature, extend the service life of the battery, and improve
the safety and reliability of electric vehicles.
2. Power grid energy storage
- In the power grid energy storage system, a large number of energy
storage batteries need to work stably under different environmental
conditions.
- Special phase change materials for 45℃ batteries can effectively
adjust the temperature of the battery, ensure that the battery
maintains good performance during the charging and discharging
process, improve the efficiency and reliability of the power grid
energy storage system, enhance the stability and flexibility of the
power grid, and promote the large-scale access and consumption of
renewable energy.
3. Space vehicle power supply system
- Battery is one of the important power sources in space vehicle.
- Phase change materials can provide effective temperature control
for space batteries, prevent batteries from being damaged by
extreme temperature changes in space, ensure the stable performance
of batteries during launch and in-orbit operation, and ensure the
smooth progress of space missions.
