Our first consideration when choosing batteries is safety. Lithium iron phosphate batteries are becoming increasingly popular. Are they safe?
This article discusses the safety of lithium iron phosphate batteries.
Part 1. Safety of LiFePO4 Batteries
This section discusses why lithium iron phosphate batteries, also known as LiFePO4 and LFP batteries, are safe.
First of all, the phosphate-oxide bond in LiFePO4 batteries is stable. Even when overcharged, the phosphate-oxide bond will not break down.
Additionally, lithium iron phosphate cells are non-combustible and can withstand harsh conditions, such as freezing temperatures and scorching sunshine.
Moreover, LiFePO4 batteries have a built-in battery management system (BMS) which keeps them from overcharging, overcurrent, short-circuiting, etc.
Part 2. Benefits of LiFePO4 Batteries
There are many other advantages to LFP batteries besides their high safety.
LiFePO4 batteries are lightweight and deliver high energy density while being about 2/3 the weight of lead-acid batteries.
Low Self-discharge Rate
It is possible to leave LiFePO4 batteries standing for months without causing damage since they have a low self-discharge rate of less than 3% per month.
Fast charging reduces the batteries’ downtime and improves their efficiency. LiFePO4 batteries charge much faster than lead-acid batteries.
It is possible to use LiFePO4 batteries for 5,000 cycles at 80% depth of discharge without affecting their performance.
Additionally, LiFePO4 batteries require little maintenance and infrequent replacement, making them an ideal investment for solar energy storage systems, boats, and golf carts.
