PHI Battery Safety & Green Attributes,
Certifications
This Appendix section covers the PHI Battery safety attributes and certifications, such as the lack of thermal
runaway with fire propagation, off-gassing, UN DOT certification and UL compliance and certification. It also covers
the PHI Battery’s green attributes –
from products to materials to disposal, as well as relevant environmental and
ecological considerations.

Safety Attributes and Certifications
B.1.1
–
Intrinsically Safe Operation and Installation
The PHI Lithium Ferrous Phosphate (LFP) battery cell component is made with an intrinsically safe cathode
material (iron phosphate). This creates a strong molecular bond, which withstands extreme conditions,
prolongs cycle life, and maintains integrity with little or no maintenance over extended periods of time.
There is virtually no danger of Thermal Runaway with fire propagation, as there may be with Lead Acid,
NiCd, and Lithium Cobalt type batteries (NCA, NMC, LCO). No venting or cooling is required. No
precautions or special structural considerations are necessary when installing PHI Batteries.
B.1.2
–
No Safety Hazards due to Off-Gassing, Exposure to
Acids, Thermal Runaway
PHI Batteries do not vent dangerous gasses during normal operation, such as hydrogen and oxygen,
because chemicals contained in Lithium Ferro Phosphate cells’ electroly
te do not electrolyze to any
appreciable extent within the PHI Battery’s operating voltage range. In
contrast, lead acid batteries which
contain water and sulfuric acid experience significant electrolysis into H2 and O2 during normal operation.
There are no dangers of exposure to sulfuric acid because PHI Batteries do not have caustic electrolytes.
Thermal runaway with fire propagation is not an issue with PHI products due to the basic nature of Lithium
Ferro Phosphate cell chemistry utilized in all our power storage products.
B.1.3
–
PHI Battery Control and Protective Circuitry
SimpliPhi Power Inc. utilizes balancing, voltage regulation, thermal and current controls, as well as other
protective measures, in its PHI Battery Management System (BMS). This protective circuitry is embedded in
the architecture of each PHI Battery.
B.1.4
–
UN DOT Certified Cells
The Lithium Ferrous Phosphate (LFP) cells are independently certified to withstand the UN DOT 38.3
testing guidelines with no special circuitry added. These tests include short circuit, over-voltage,
overcharging, extreme temperature, high altitudes, shock and extreme vibration testing.
B.1.5
–
UL Compliance
The Lithium Ferrous Phosphate cells within the PHI Batteries fully comply with the safety testing
parameters of UL 1642.
B.1.6
–
RoHS Compliant
SimpliPhi Power 3.8 Batteries are RoHS compliant. Any RoHS compliant component is tested for the
presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated
biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium,
