GRAPHENE Smart 12 Volt 100AH Lithium(LFP) Inverter Battery Solar Compatible Backup 180Ah+ Lead-Acid Long Life Upto 30 Years(4000+ Cycles) Works with Any Normal Inverter, 5+2 Years Warranty

Graphene LFP (Lithium Iron Phosphate) batteries are safer than both lead-acid and other lithium-ion battery chemistries.

• Chemistry: LFP is a type of lithium-ion battery, its chemistry differs significantly from other lithium-ion chemistries like NMC (Nickel Manganese Cobalt Oxide) and NCA (Nickel Cobalt Aluminum Oxide).
• Non-hazardous: LFP batteries are free of above-mentioned hazardous chemical substances and have a significantly lower fire risk.
• Inherent stability: The chemical composition of LFP makes it less reactive and more stable compared to other battery chemistries.
• Thermal stability: LFP batteries have excellent thermal stability, meaning they are less likely to overheat and catch fire under extreme conditions. Other lithium-ion chemistries are more prone to thermal runaway.
• No heavy metals: LFP batteries don't contain heavy metals.

Lead-acid batteries contain toxic materials (lead and sulfuric acid) that can cause serious harm if leaked or mishandled.

Corrosive Electrolyte:

• Sulfuric acid: The primary electrolyte in lead-acid batteries is sulfuric acid, a highly corrosive substance that can cause severe burns if it comes into contact with skin or eyes.
• Environmental hazard: Sulfuric acid spills can also damage surfaces and contaminate the environment.
• Fire risk: Lead-acid batteries are less prone to fire compared to some lithium-ion chemistries, but they can still generate sparks and ignite flammable materials under certain conditions.

Explosive Gases:

• Hydrogen and oxygen: During charging, lead-acid batteries produce hydrogen and oxygen gases. These gases can form a flammable mixture that can ignite and cause an explosion if not properly ventilated.
• Confined spaces: Working with lead-acid batteries in confined spaces can increase the risk of explosion due to the accumulation of these gases.

Except LFP, Other lithium-ion contains chemistries like Nickel Manganese Cobalt Oxide & Nickel Cobalt Aluminum Oxide. These are more prone to thermal runaway.

Thermal Runaway:

• Exothermic reaction: Under certain conditions, lithium-ion batteries can undergo a rapid, exothermic reaction that can lead to a fire or explosion. This is often triggered by factors like overcharging, short circuits, or external heat sources.
• Rapid temperature rise: Once thermal runaway starts, the battery's temperature rises quickly, accelerating the reaction and potentially causing a fire.

Fire and Explosion Risk:

• Flammable electrolytes: The electrolytes used in lithium-ion batteries are often flammable, especially in higher energy density cells. These electrolytes can ignite if exposed to a heat source or during thermal runaway.
• Toxic fumes: When lithium-ion batteries burn, they release toxic fumes, including hydrogen fluoride and other harmful substances.
