Address: BAK industry park, Kuichong Street, Longgang District, Shenzhen City, Guangdong Province, China Telephone: +86-755-89770063 Section 2 Composition/Information on Ingredients
Weight Percentage/％ Molecular formula Lithium cobalt oxide Carbon（such as hexaflurophosphate Organic carbonates Nickel, PVDF, others Section 3 Hazards Identification
The lithium ion cells are not hazardous when used according to the instructions of manufacturer under normal conditions. In case of abuse, there's a risk of rupture, fire, heat, leakage of internal components, which could cause casualty loss. Abuses include but not limited to the following cases: charge for a long time, short circuit, put into fire, whack with hard object, puncture with acute object, crush, broken. Section 4 First-aid Measures
The lithium cells are not hazardous with eye and skin contact under normal circumstance. In case of fire or rupture, the leakage of internal hazardous substance and formation of hazardous substance would occur, take the following measures if contact with it: Eye : Check for and remove any contact lenses. Immediately flush with plenty of clean water for File No./Rev.:MSDS-061/D

at lest 15 minutes, seek medical assistance; Skin: Immediately flush with plenty of clean water for 15 minutes; seek medical assistance if Inhalation: If inhaled, remove to fresh air immediately, seek medical assistance, and ventilate the contaminated area. Ingestion: Rinse mouth with clean water immediately, activate vomit under the direction of expert, and seek medical assistance. Section 5 Fire-fighting Measures
Extinguish with plenty of water, dry powder extinguishers, sands, earth. Combustion products and decomposed products by contact of water or air with internal substance include: carbon monoxide, carbon dioxide, hydrogen fluoride, phosphorus fluoride. Section 6 Accidental Release Measures
When leakage of cells happens, liquid could be absorbed with sands, earth or other inert substance, and the contaminated area should be ventilated meantime. Section 7 Handling and Storage
Don't handle and store cells with metalwork. Store and use far away from heat, sparks, open flame, or any other ignition source, and under room temperature (<30℃) in ventilating and dehumidifying environments. Section 8 Exposure Controls/Personal Protection
There is no need for protect under normal conditions. In engineering aspect, ventilation equipment should be installed. Gas mask, blinkers, gloves enduring chemical erosion and exposure suit are required when dealing with fire and leakage. Section 9 Physical and Chemical Properties
Cells are not single chemical material; there are no specific physical and chemical properties such as melting point and boiling point. Main purpose of lithium cells: used in notebook computers. Section 10 Stability and Reactivity
Cells are safe under normal conditions. The following substance might appear after catching fire or leakage: organic carbonate, hydrogen fluoride, carbon monoxide, carbon dioxide, phosphorus Section 11 Toxicological Information
Cells are not hazardous when used properly. If the cells catch fire or the internal substance leaks, combustion products and decomposed products might have irritation and toxicity to skin, eye and respiratory systems. Toxicity data of some substance are listed following: Hydrogen fluoride: Extremely toxic, May be fatal if inhaled or ingested. Readily absorbed through the skin contact may be fatal. Possible being mutagen. LCLO: 50 ppm/30m (human beings)，LC50： 1276 ppm/1h File No./Rev.:MSDS-061/D

Carbon and graphite: It is slightly hazardous in case of skin contact (irritant), ingestion, or inhalation and cause chronic damage to upper respiratory tract and cardiovascular system. Dust may cause respiratory irritation. LD50: 3.5 mg kg-1(mouse). There is no hazard. Dust may be harmful to respiratory system. LD50:30mg/kg（rat）. Section 12 Ecological Information
There is no influence to ecology and environment when used properly. Section 13 Disposal
Deserted cells couldn't be treated as ordinary trash. Be put to garbage box which recycle batteries after being placed into plastic bags or be dealt as special trash. Couldn't be thrown into fire or placed in high temperature. Couldn't be dissected, pierced, crushed or treated similarly. The package and plastic box which contain cells could be treated as ordinary trash. Best way is Section 14 Transport Information
For the international transport of lithium batteries, they must comply with these regulations: the International Maritime Dangerous Goods (IMDG) Code by International Maritime Organization (IMO), Dangerous Goods Regulations (DGR) by International Air Transport Association (IATA) and Technical Instructions for the Safe Transport of Dangerous Goods by Air (TI) by International Civil Aviation Organization (ICAO). These regulations are based on the UN Recommendations on the transport of Dangerous Goods, Manual of Tests and Criteria. Lithium batteries which meet the requirements of UN38.3 (UN Manual of Tests and Criteria, Part III, subsection 38.3) could be transported by air and by sea as ordinary goods, otherwise should be transported according to Class 9, Packing Group II hazardous goods. As the published of the UN Recommendations on the transport of Dangerous Goods, 51th edition (2010), all these regulations have added some new contents to regulate the transport of lithium ion batteries. And they should be complied since 1 January 2009. 1. For lithium ion batteries, UN ID number is 3480. For lithium ion batteries contained in equipment or lithium ion batteries packed with equipment, UN ID number is 3481. 2. The consignment should be fully described by proper shipping name and packed, marked and in proper condition for carriage by air. The consignment is not classified as dangerous under the current edition of the IATA 51th Effective, Dangerous goods regulation and all applicable carrier and government regulations. 3. For transported by air, Lithium-ion Cells/Batteries shipped as "Not Restricted" Cargo: Must comply with SECTION Ⅱ of P1965-P1967 accordingly; For cells, the Watt-hour rating File No./Rev.:MSDS-061/D

should not be more than 20Wh; For batteries, the Watt-hour rating should not be more than 100Wh. Watt- hour rating must be marked on the outside of the battery case (marked by manufacturer). (Except those that were manufactured before 1 January 2010, which may be transported without this marking until 31 December 2011). 4. Each consignment must be accompanied with a document such as an air waybill with an indication. For those Lithium ion cells/ batteries contained in equipment, the equipment must be equipped with an effective means of preventing accidental activation. 5. Quantity per package shall not exceed 10kg. 6. Each package must be capable of withstanding a 1.2m drop test in any orientation without damage of cells or batteries contained therein. 7. Lithium batteries which meet the requirements of A154 could be transported by air, and the batteries manufactured by BAK meet these requirements.( A154 Lithium batteries identified by the manufacturer as being defective for safety reasons, or that have been damaged, that have the potential of producing a dangerous evolution of heat, fire or short circuit are forbidden for transport. ) 8. Cells and batteries must be protected so as to prevent short circuits. This includes protection against contact with conductive materials within the same packaging that could lead to short Section 15 Regulatory Information
There is no regulation on lithium batteries management. Section 16 Other Information
This information is not effective to all the cells manufactured by BAK. This information comes from reliable sources, but no warranty is made to the completeness and accuracy of information contained. BAK doesn't assume responsibility for any damage or loss because of misuse of cells. Users should grasp the correct use method and be responsible for the use of cells. File No./Rev.:MSDS-061/D
