A lithium battery comprising a plurality of electrochemical cells assembled together and a rigid casing forming an enclosure. The plurality of electrochemical cells includes: at least one first electrochemical cell, at least one second electrochemical cell; and at least one third electrochemical cell disposed between the at least one first electrochemical cell and the at least one second electrochemical cell. The at least one first electrochemical cell is disposed between a first wall of the casing and the at least one third electrochemical cell. The at least one second electrochemical cell is disposed between a second wall of the casing and the at least one third electrochemical cell. The first and second walls provide a heat sink path to dissipate excess heat generated by the plurality of electrochemical cells. The at least one first and second electrochemical cells are more capacitive than the at least one third electrochemical cell.

Battery with variable electrochemical cells configuration

A lithium battery comprising a plurality of electrochemical cells assembled together, the electrochemical cells assembled with electrochemical cells of different characteristics to compensate the heat loss through heat sinks in the battery.

Battery with electrochemical cells having variable impedance

The invention disclosed is a method for decreasing the internal resistance or impedance of a battery or electrochemical cell is described which comprises the step of discharging the battery or cell until it reaches an overdischarge condition and maintaining the battery or cell in the overdischarge condition for a period of time sufficient to effect a diminution of the internal resistance or impedance of a battery or electrochemical cell; and a battery or electrochemical cell having a reduced impedance.

Electrochemical cell or battery with reduced impedance and method for producing same

An electrode and an electrode material for lithium electrochemical cells are disclosed. The electrode material is in powder form and has a particle size distribution wherein the measured particle size distribution of the electrode material has a median size Dranging from 1.5 &#x3bc;m and 3 &#x3bc;m, a D&#x2267;0.5 &#x3bc;m, a D&#x2266;10.0 &#x3bc;m, and a calculated ratio (D/D)/D&#x2267;3.0 which is indicative of a peak of the measured particle size distribution on the left of the median Dwhich improves the loading and energy density of the electrode produced with this electrode material powder.
