\"Eliiy\"<\/a>                         L<\/span><\/strong>es \u00e9nergies alternatives \u00e9oliennes ou solaires pr\u00e9sentent un grave d\u00e9faut: elles sont intermittentes et bien souvent impr\u00e9visibles. Il existe donc tout un pan d’activit\u00e9s de R&D qui se penche sur le stockage d’une partie de l’\u00e9nergie g\u00e9n\u00e9r\u00e9e, afin de pouvoir la mobiliser lorsque la source primaire fait d\u00e9faut. C’est le cas en l’absence de vent ou lors d’une temp\u00eate pour l’\u00e9olien, les soirs, les matins, la nuit ou par temps nuageux pour le solaire. Ces moyens de mise en r\u00e9serve vont du stockage adiabatique d’air comprim\u00e9 et chaud dans les poches souterraines, \u00e0 l’utilisation d’immenses r\u00e9serves de sels fondus<\/a>. Pour les micro stockages concernant un foyer disposant de panneaux solaires par exemple, une possibilit\u00e9 est d’utiliser des batteries en tampon qui vont se charger durant la journ\u00e9e et vont se d\u00e9charger d\u00e8s qu’il n’y a plus d’ensoleillement suffisant pour alimenter le foyer. <\/p>\n

                    Une start-up japonaise veut se lancer dans ce cr\u00e9neau.<\/p>\n

                        Sharp, fabricant mondial de panneaux solaires, Dai Nippon Printing qui poss\u00e8de les proc\u00e9d\u00e9s de productions d’\u00e9lectrodes au Japon et Daiwa House Industry qui est dans la construction immobili\u00e8re ont pris des parts dans une start-up japonaise Eliiy Power qui dit avoir d\u00e9velopp\u00e9 une batterie de type Lithium-Ion, de 18 kWh, \u00e9nergie suffisante pour alimenter un foyer \u00e9quip\u00e9 de panneaux solaires. En effet les panneaux fournissent environ les 3\/4 des 12 kWh n\u00e9cessaires au bon fonctionnement d’un foyer Japonais. Cette batterie serait \u00e9quip\u00e9e de tous les dispositifs de s\u00e9curit\u00e9 ad hoc et son co\u00fbt serait insensible aux cours des mat\u00e9riaux on\u00e9reux \u00e0 base d’oxydes de Cobalt, de Nickel ou de Mangan\u00e8se classiquement utilis\u00e9s dans les batteries Lithium-Ion; mais la composition des \u00e9lectrodes n’est pas pr\u00e9cis\u00e9e. La batterie pourrait \u00eatre vendue pour moins de 500 mille yens (3000 euros). Eliiy Power aurait l’intention, d’apr\u00e8s le Nikkei Business daily, de construire une usine de production \u00e0 Kawasaki pour pouvoir fournir les premi\u00e8res batteries en 2009\/2010. <\/p>\n

                        Le principal challenge est de pouvoir fabriquer ce produit sophistiqu\u00e9 \u00e0 moins d’un euro les 6 Wh. Cela suppose une production de masse standardis\u00e9e, n’utilisant que des composants \u00e9conomiques.<\/p>\n

                        En France, le projet Solion<\/a>, coordonn\u00e9 par la SAFT, dans le cadre du p\u00f4le de comp\u00e9titivit\u00e9 Tenerdis<\/span> travaille sur un sujet analogue.<\/p>\n","protected":false},"excerpt":{"rendered":"
