Q: what cause macbook pro battery swelling? Apple battery packs contain a set of 6 lithium Ion (Li-Ion) cells (the metal covered envelopes), connectivity circuitry, and a small logic board. The main cause for battery cell swelling is what is known as thermal runaway. If a cell reaches a certain temperature then a chemical in the cell (usually Cobalt Oxide for Lithium Ion batteries) starts an unintended reaction which is exothermic in nature (i.e. it creates heat).
Sodium balance. In addition to regulating total volume, the osmolarity (the amount of solute per unit volume) of bodily fluids is also tightly regulated. Extreme variation in osmolarity causes cells to shrink or swell, damaging or destroying cellular structure and disrupting normal cellular function.
