May 30 2025Case: Improper use of lithium iron phosphate battery cells poses safety risks
Executive Summary
A user directly installed the lithium iron phosphate battery cell in a home energy storage system in an exposed environment without any protective facilities. No protective battery box was installed, and it was exposed to the open outdoor environment for a long time. Only half a year later, the battery had the following problems:
1.Shell corrosion and short circuit risk : Rainwater infiltration caused serious corrosion of the battery shell, oxidation of the battery contact point, causing local short circuit, and the battery capacity dropped by 30%;
2.Temperature runaway : The battery surface temperature exceeded 60℃ under the sun in summer, and the low temperature in winter (-10℃) caused the electrolyte activity to decrease, and the charging and discharging efficiency was reduced by 40%;
3.Physical damage : Strong winds carried sand and stones to hit the battery shell, causing the battery structure to loosen, and there was a risk of thermal runaway;
4.System downtime : Due to the lack of protection, the battery failure caused the entire energy storage system to shut down, and the user's daily additional electricity bill increased by $20.
Summary of the hazards of long-term exposure of battery cells:
Shortened lifespan: The lifespan of lithium iron phosphate batteries in an open environment drops sharply from the nominal 8 years to 2-3 years;
Safety hazards: The risk of corrosion, short circuit, and thermal runaway increases, which may cause fire or electric shock accidents;
Loss of economic efficiency: The cost of frequent battery replacement far exceeds the initial investment.

Solution: The core advantages of battery boxes
Using Xiho lithium iron phosphate battery box can systematically avoid the above risks and achieve:
1.All-weather protection: IP67/IP68 waterproof and dustproof design, prevent rain and dust from intruding, and extend the battery life to more than 10 years;
2.Temperature control optimization: integrated heat dissipation fins and insulation layer, cooling 15℃ in summer and 5℃ in winter, maintaining the best working temperature of the battery cell (20-35℃);
3.Structural reinforcement: metal frame + anti-seismic buffer design, impact resistance level up to IK10, adapt to extreme environments such as strong winds and heavy rains along the coast;
4.Intelligent management: built-in BMS (battery management system), real-time monitoring of voltage and temperature, automatic balance of battery cell status, avoid overcharge and over discharge.
Application scenario adaptation:
Home energy storage system: 5KWh wall-mounted battery box perfectly matches rooftop photovoltaic + household electricity needs;
Solar energy storage system: 15KWh stacked/vertical battery box supports off-grid residential or off-island microgrid deployment;
Commercial and industrial energy storage: Flexible capacity expansion, adaptable to solar + wind hybrid energy system.
