Reagents for battery researchReagent for battery research
Kanto Chemical have a range of electrolyte and dehydrated solvents that can beused as battery research. The field of battery research, including lithium-ion
batteries, sodium-ion batteries and potassium-ion batteries, is attracting increasing
attention as an important area for achieving carbon neutrality.
In addition to lithium-ion batteries using flame-retardant ionic liquids and solid
electrolytes, research and development is also being conducted on sodium-ion
batteries and potassium-ion batteries as candidates for new secondary batteries toreplace lithium-ion batteries.
Kanto Chemical offer a full range of peripheral reagents to meet the needs of ourcustomers. We also handle mixed solvents, so please contact your local sales
office for further information.

Electrolytes
The electrolyte acts as a source of metal ion(M+), which are essential for
charging and discharging the battery.
(Lithium ion batteries: Li+, sodium ion batteries: Na+, potassium ion batteries :K+)
Typical anion species

The structural formulae of commonly used electrolytes are given below.

Tetrafluoroborate saltsHexafluorophosphate salts

Bis(fluorosulfonyl)imide salts

Perchlorate salts

Trifluoromethanesulfonic acid salts

Bis(trifluoromethanesulfonyl)imide salts

As for the lithium salts on the next page, in addition to low moisture values, they
are offered with standard guarantees for metals and other substances.
In addition, the glass containers are filled with argon gas and packaged in lamizip (argon-filled) with desiccant as outer packaging. (After use, the container andthe lami-zip should be replaced with inert gas to avoid air contamination.)
Please use the product not only as a reagent for battery research, but also in awide range of applications from precursors for ionic liquids to applications wherehigh purity is required

Mixture Solvent 【for electrochemistry】
The electrolyte used in lithium-ion batteries is generally a mixture of cyclic carbonates such as
ethylene carbonate (EC) and chain carbonates such as dimethyl carbonate (DMC) and ethyl
methyl carbonate (EMC). We offer a wide range of mixed solvent products. Please contact yourlocal sales office for customized formulations and other requirements.
