Categories Materials Properties Potential environmental pollution
Cathode
material
LiCoO2/LiMn2O4/LiNiO2
/LiNiCoMnO2
Reacts with water, acids, reducing agents or strong
oxidizing agents (hydrogen peroxide, chlorate, etc.)
to produce harmful metal oxides.
Heavy metal pollution raises the
environmental pH
Anode material Carbon material / graphite,
lithium intercalation
in case of fire or high temperature, dust can explode
and react with strong acid and strong alkali to
produce gases such as CO and CO2.
The CO and solid dust particles
produced by the combustion of the
anode material contaminate the air.
Electrolyte LiPF6/LiBF4/LiAsF6It is highly corrosive and can produce HF when
exposed to water, and can be oxidized to produce
toxic substances such as P2O5, Li2O, B2O3
Fluorine pollution changes the pH of
the environment, and the toxic gas
generated pollutes the air and
stimulates the human body through
the skin and breathing.
Electrolyte
solvent
Ethylene carbonate /
Propylene carbonate /
Dimethyl carbonate
The hydrolyzate produces aldehydes and acids,
which can produce CO, CO2, etc.
Organic matter such as aldehydes,
ketones, and methanol
Separator PP/PE Combustion can produce CO, aldehyde, etc. Organic pollution
Binder PVDF、VDF、EPD It can react with fluorine, fuming sulfuric acid, strong
alkali, alkali metal, and decompose by heat to
produce HF.
Thermal decomposition produces HF
and fluorine pollution
