Handbook of Battery Materials (2nd ed.) by Claus Daniel (ebook)
The absolute best book overall on batteries in general covering both primary and secondary type cells. An excellent reference to have on hand.
Excellent value and thorough coverage of the chemistry of ionics. No stone left unturned here. Publisher: Springer; 2nd edition January 31, Excellent value and thorough coverage of the chemistry of electrodics. Again, no stone left unturned. Publisher: Springer; 2nd edition January 1, Excellent value and thorough coverage of the chemistry of electrodics in chemistry, engineering, biology, and environmental science.

I contribute this web that speaks about the industrial batteries, batteries rectifier and battery chargers. Thin aluminum and copper foils serve as current collectors for the electrodes.

The electrode layers consist to a large extent of active materials lithium ion storage particles which can reversibly host lithium ions. During charge, the lithium ions are transported and intercalated in the anode. During discharge, the lithium ions are accepted by the lattice structure of the Li-transition metal-oxide in the cathode. The amount of lithium ions that can be stored by the active materials determines cell capacity.
In commercial cells, graphite is a common active material for the anode . On the cathode side, lithium metal oxides in various compositions are used. Besides the active materials, the electrode coating also comprises a polymer binder and carbon. The polymer binder for example polyvinylidendifluorid PVDF provides the cohesion of the active materials as well as their adhesion to the metallic current collector.
The better the electrical connectivity, the lower the internal resistance of the electrode layer . Owing to their small size — often only a few nanometers — carbon black particles are embedded in the binder matrix. The binder material itself has a low conductivity, thus oversupply of binder should be avoided. Materials and Methods Two commercial prismatic lithium ion battery cells 3. One cell was investigated in the pristine state, the other cell was subject to a ageing procedure comparable to several years of use in a mobile device.
The cells were discharged and then opened in a glove box under protective argon atmosphere. Subsequently, the electrode foils were separated, washed in dimethyl carbonate DMC , and dried. Small samples were cut from the electrodes and the separator. The samples were placed as obtained on a microscopy stub and secured with a carbon tape as well as molded into an epoxy resin for cross section analysis.
