Non Rechargeable Lithium Iron Disulfide Battery Introduction

From:CTECHI GROUP Limited     Release time:2018-09-25

Overview:All one-off batteries generate a small amount of hydroxide gas on discharge and battery-powered devices must have vents. Pressure generated in the cell can break the seal and cause corrosion. This is visible in form of a feathery crystalline structure that can develop and spread to neighboring parts in the device and lead to damage.

Non rechargeable lithium iron disulfide battery ( non rechargeable Li-FeS2 battery ) is a newcomer to the one-off battery family and offers improved performance compared to alkaline. Lithium batteries normally deliver 3 volts and higher, but non rechargeable Li-FeS2 battery has 1.5 volts to be compatible with the AA and AAA formats. It has a higher capacity and a lower internal resistance than alkaline. This enables moderate to heavy loads and is ideal lithium iron disulfide batteries for digital camera. Further advantages are improved low temperature performance, superior leakage resistance and low self-discharge, allowing 15 years of storage at ambient temperatures.

The disadvantages of the Li-FeS2 are higher cost and transportation issues due to the lithium metal content in the anode. In 2004, the US DOT and the Federal Aviation Administration (FAA) banned bulk shipments of primary lithium batteries on passenger flights, but airline passengers can still carry them on board if the allotted lithium content is not exceeded the standard. Each AA-sized non rechargeable lithium iron disulfide battery has 0.98 grams of lithium; the air limitation of primary lithium batteries is 2 grams (8 grams for rechargeable Li-ion). This restricts each passenger to two cells, but exceptions have been made in which 12 sample batteries can be carried.

The Li-FeS2 includes safety devices in the form of a positive thermal coefficient (PTC) that limits the current at high temperature and resets when normal. The Li-FeS2 cell cannot be recharged as is possible with NiMH in the AA and AAA formats. Recharging, putting a cell in backwadrs, mixing in a depleted cell or adding a foreign cell could cause a leakage or explosion.
