| titleOfInvention | Low-temperature lithium battery |
| abstract | The invention discloses a low-temperature lithium battery, which comprises a positive pole piece, a negative pole piece, a diaphragm, electrolyte and a shell, wherein the negative pole material of the negative pole piece comprises the following components in percentage by mass: 1-1.2, wherein the composite graphite is graphite coated by hard carbon, and the mass ratio of the hard carbon to the graphite is 0.01-0.05: 1, the raw material of the plant hard carbon is one of coconut shells and walnut shells; the electrolyte consists of an organic solvent, an electrolytic lithium salt and an additive, wherein the concentration of lithium ions in the electrolytic lithium salt is 0.9-1.0 mol/L, the mass percent of the additive is 3% -4%, and the balance is the organic solvent; the organic solvent comprises the following components in a mass ratio of 10: 1-2 of ethylene carbonate and propylene carbonate, wherein the electrolytic lithium salt comprises the following components in percentage by mass: 1 lithium tetrafluoroborate, lithium dioxalate borate, the additive comprising vinylene carbonate. The invention improves the low-temperature discharge performance of the lithium battery by designing the reasonable negative and positive electrode materials and the electrolyte. |
