The traditional battery configuration incorporates a negative electrode, or anode, which acts as a host insertion material for alkali metal ions. This host anode is necessary due to the unstable metal plating chemistry, especially for lithium, in known electrolyte media. In this talk, I will discuss our recent efforts to develop the anode-free battery, or a full-cell battery configuration...
There are a number of opportunities to increase Li-ion battery energy density. At the negative electrode, Si alloys can store much more lithium than graphite, which is currently in use. As a result, utilizing Si alloys in Li-ion cells has been shown to increase energy density by about 20%. However, there are many challenges for the utilization of Si alloys in practical Li-ion batteries. ...
An in-situ technique for monitoring the pressure evolution of volumetrically constrained Li-ion pouch cells has previously been introduced by Louli et al.[1] When constrained, changes in cell volume cause a pressure response that is measured. A reversible pressure change is observed due to the reversible electrode volume expansion and contraction during charge and discharge of the cell.[1] ...
There is a continual push to improve the energy density of lithium-ion batteries, but this is becoming increasingly difficult as it is believed that many of the best electrode materials have been found and optimized. In order to achieve higher energy densities to meet future storage demands it may be necessary to move “beyond lithium-ion”.
Recent research efforts have focused on reviving the...
