A heat absorbing pack for a secondary battery module includes a super absorbent matrix and a heat-dissipating structure. The super absorbent matrix is impregnated with water inside the pouch and the heat-dissipating substrate is inserted between the super absorbent matrix and the pouch, so that it can absorb a large amount of heat from the surroundings when heat is generated inside the module. Therefore, it is possible to prevent the ambient temperature of the secondary battery from changing rapidly. Furthermore, the super absorbent matrix can be uniformly exposed to ambient thermal energy to prevent damage to the heat absorbing pack due to heat generation inside the module. Accordingly, the heat absorbing pack provides more stable temperature control inside the module, which can improve the performance and stability of the secondary battery according to the ambient temperature.

A process and system are disclosed for producing lithium oxide from lithium nitrate. In the process and system, the lithium nitrate is thermally decomposed in a manner such that a fraction of the lithium nitrate forms lithium oxide, and such that a remaining fraction of the lithium nitrate does not decompose to lithium oxide. The thermal decomposition may be terminated after a determined time period to ensure that there is a remaining fraction of lithium nitrate and to thereby produce a lithium oxide in lithium nitrate product. The lithium oxide in lithium nitrate product may have one or more transition-metal oxides, hydroxides, carbonates or nitrates added thereto to form a battery electrode. The lithium oxide in lithium nitrate product may alternatively be subjected to carbothennal reduction to produce lithium metal.
