Wet and vented seems quite common for these.

Litiumbatterien sind aufgrund der verwendeten Elektrolyten üblicherweise stark hygroskopisch und können bei eindringender Feuchtigkeit explodieren. Deshalb werden sie hermetisch dicht verschweist. Diese Gefahr kann bei neueren Typen durch nicht-hygroskopische Elektrolyten eleminiert werden, sodass auch offene Varianten möglich sind. Wesentliches Unterscheidungsmerkmal ist also der feste oder flüssige Elektrolyt.

Eine Lithiumbatterie ist eine Primärzelle, bei der Lithium als aktives Material in der negativen Elektrode verwendet wird. Sie ist im Gegensatz zum Lithium-Ionen-Akkumulator nicht wieder aufladbar, obwohl letztere häufig ebenfalls als Lithiumbatterie bezeichnet werden. 
:
Die hohe Reaktivität von elementarem Lithium (beispielsweise mit Wasser oder bereits mit feuchter Luft) ist allerdings bei der praktischen Umsetzung problematisch. Deshalb können in Lithiumbatterien ausschließlich nicht wässrige, aprotische Elektrolytlösungen, wie zum Beispiel Propylencarbonat, Acetonitril oder Dimethoxyethan, oder Festelektrolyte verwendet werden.

Research has been under way in the area of non-flammable electrolytes as a pathway to increased safety based on the flammability and volatility of the organic solvents used in the typical electrolyte. Strategies include aqueous lithium-ion batteries, ceramic solid electrolytes, polymer electrolytes, ionic liquids, and heavily fluorinated systems.
:
Liquid electrolytes in lithium-ion batteries consist of lithium salts, such as LiPF
6, LiBF
4 or LiClO
4 in an organic solvent, such as ethylene carbonate, dimethyl carbonate, and diethyl carbonate.[57] A liquid electrolyte acts as a conductive pathway for the movement of cations passing from the negative to the positive electrodes during discharge

Aqueous and nonaqueous lithium-air batteries enabled by water-stable lithium metal electrodes
The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for next-generation battery development. However, there are a number of challenging technical hurdles that must be addressed for Li-Air batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg.

A 63 m Superconcentrated Aqueous Electrolyte for High-Energy Li-Ion Batteries
A water-in-salt electrolyte (WiSE) offers an electrochemical stability window much wider than typical aqueous electrolytes but still falls short in accommodating high-energy anode materials, mainly because of the enrichment of water molecules in the primary solvation sheath of Li+. Herein, we report a new strategy in which a non-Li cosalt was introduced to alter the Li+-solvation sheath structure.

Hybrid Electrolyte Bridges Gap Between Aqueous and Non-aqueous Battery Technology

A unique characteristic of this design is that it can be manufactured in open-air.
“Conventional Li-ion batteries, by comparison, require a rigorous moisture-free environment – a dry-room is a must,” Professor Wang explained.
