An electrochemical cell includes an anode composed of a salt, a cathode insulated from the anode and a non-aqueous electrolyte in contact with the anode. The electrolyte may include an organic solvent that comprises at least approximately one percent by volume trimethylene carbonate.

Carbonate solvent for electrolytes in lithium and lithium ion cells

A more efficient LiPFlithium-ion electrochemical system composed of a phosphate free, borate lithium salt electrolyte LiTPTB composed of LiBCFHin a ternary mixed organic solvent containing a 1:1:1 volume ratio of EC, DMC and EMC is provided. The borate salt of the LiTPTB electrolyte decomposes at temperatures above 110&#xb0; C. and does not react with water and also has an oxidation potential of about 4.4 V versus lithium, making it suitable for use in high voltage lithium-ion cells and batteries. A 0.3 to 1.0 M molar concentration of LiTPTB composed of LiBCFHin a ternary mixed organic solvent containing a 1:1:1 volume ratio of EC, DMC and EMC is also provided.

Method for using battery charger adapter for military vehicles

A NATO DC slave plug adapter for use in providing controlled DC power from he battery of a military vehicle to charger devices for recharging Army communication batteries includes an automatic safety switch which cuts off the load on the vehicle battery when the battery voltage falls to a critical level. The critical level may be generally determined by the amount of charge necessary in the vehicle battery to start or reliably operate the vehicle.
