DOE, Stanford researchers bring “dead” lithium batteries back to life

Electrek

The lithium-ion batteries found in most modern EVs and hybrids tend to lose energy capacity as they cycle (get charged, get spent, and get re-charged). That happens because small bits of lithium can be cut off from the battery’s electrodes during the charging process.

Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates. Sasaki et al.

Berkeley Lab researchers shed light on how lithium-rich cathodes work, opening the door to higher capacity batteries

Green Car Congress

The traditional design paradigm for Li-ion battery cathodes has been to create compounds in which the amount of extractable Li + is well balanced with an oxidizable transition metal (TM) species (such as Mn, Fe, Co or Ni) to provide the charge-compensating electrons, all contained in an oxide or sulfide host.
